TEA5880TS
Integrated FM stereo radio IC for host processor tuning in
handheld applications
Rev. 02 — 26 April 2004
Preliminary data sheet
1. General description
The TEA5880TS stereo FM radio IC dramatically reduces the printed-circuit board area
(only 100 mm2) needed to integrate FM radio functionality into portable devices. This
makes it invaluable for any application where space is at a premium.
Relying on a system host processor for radio tuning, the TEA5880TS is ideally suited for
powerful devices such as PDAs, notebooks, portable CD and MP3 players.
2. Features
■ No alignments necessary
■ Complete adjustment-free stereo decoder; no external crystal required
■ Fully integrated MPX VCO circuit
■ Fully integrated low IF selectivity and demodulation
■ The full integration level means no or few external components required
■ No external FM discriminator needed due to full integration
■ Built-in adjacent channel interference total reduction (no 114 kHz, no 190 kHz)
■ The level of the incoming signal at which the radio must lock is software programmable
■ Due to new tuning concept, the tuning is independent of the channel spacing
■ Very high sensitivity due to integrated low noise RF input amplifier
■ RF Automatic Gain Control (AGC) circuit
■ Standby mode for power-down, no power switch circuitry required
■ 2.7 V minimum supply voltage
■ MPX output for RDS
■ 3-wire bus
■ In combination with the host, fast, low power operation of preset mode, manual search,
automatic search and automatic store are possible
■ Host can be in Sleep mode after tuning; a minute retuning is recommended to
compensate for temperature and voltage fluctuations
■ Covers all Japanese, European and US bands.

Depending on the antenna design the filter components at pins 1 and 2 may not be necessary. The only two remaining coils connected to pin
17 to 20 can be replaced by printed-circuit board traces that will fit underneath the TEA5880TS resulting in a design without any external
components; see Section 14 for details on the printed-circuit board coils.

FC[7:0]
FM capacitor bank switches for adjusting the FM (RF) frequency in big
steps. Every bit, when set, will switch on a capacitor with a weight
according to its position i.e. bit 0 has weight 1, bit 1 has weight 2, bit 2
has weight 4 etc, bit 6 has weight 64, except for bit 7, which also has the
same weight as bit 6; there is thus only 71⁄2 effective bits; this means
that the value range 0 to 127 will switch on different capacitors the value
range 128 to 191 switches on the same capacitors as range 64 to 127,
the value range 192 to 255 will switch on different capacitors (an
overlapped range of 64 values caused when FC[7:6] = 01b or 10b)
[1] The frequency is decreased when increasing the content of this register (more capacitors).

Integrated FM stereo radio IC for host processor tuning
8.2 Accessing the TEA5880TS
Access to the TEA5880TS can be achieved via the 3-wire bus. At the host side, the R/W
and CLOCK are output signals, while the DATA signal is bidirectional.
When powered up, the host should initialize the 3-wire bus in the host read mode as
follows:
1. Set (at host side) the DATA line into input mode
2. R/W set to LOW
3. CLOCK set to LOW.
Note: Use the following sequence for changing read/write mode:
1. To change from host read mode to host write mode proceed as follows:
a. Keep the CLOCK signal LOW
b. Set the R/W signal to HIGH (write mode)
c. Set the DATA pin (of the application controller) into output mode.
2. To change from host write mode to host read mode proceed as follows:
a. Keep the CLOCK signal LOW
b. Set the DATA pin (of the application controller) into input mode
c. Set R/W to LOW (input mode).
8.3 Writing to the TEA5880TS
Writing to the TEA5880TS is achieved with a 15-bit data pattern:
• D[14:11]: 4-bit register address
• D[10:0]: 11-bit register data.
The data pattern is sent serially to the TEA5880TS as follows:
1. Drive R/W pin HIGH to set the TEA5880TS in input mode
2. Drive the DATA pin to correct level
3. Generate positive edge of CLOCK (driving CLOCK into LOW-to-HIGH transition)
4. Delay some time to meet the data hold time requirement
5. Driving CLOCK into HIGH-to-LOW transition
6. Repeat step (2) to (5) 15 times to shift the 15-bit data pattern into the TEA5880TS
7. Drive R/W pin LOW; this signals the TEA5880TS to latch the data into the correct
register.
Note: The application should shift the LSB out first.

8.4 Reading from the TEA5880TS
Only the status or the counter register can be read from the TEA5880TS.
These are 16-bit registers and can be read serially as follow:
1. Select OS_PISO (parallel in, serial out) as output (control register A,
OUTPUT_SELECT bits)
2. Clear the PISO (control register B, PISO_CLR bit, pulse HIGH-to-LOW transition)
3. Latch the counter register (control register B, L_CNT bit, pulse HIGH-to-LOW
transition) or the status register (control register B, L_STS bit, pulse HIGH-to-LOW
transition) into the PISO
4. Drive R/W pin LOW to set the TEA5880TS in output mode
5. Read the first bit at pin DATA
6. Generate positive CLOCK pulse (LOW-to-HIGH transition)
7. Delay for a period of time to meet the data set-up time requirement
8. Read the data bit at pin DATA
9. Drive CLOCK into HIGH-to-LOW transition
10.Repeat step (6) to (9) 15 times to shift the remaining 15 bits of data out of the chip
Note: The TEA5880TS will shift the MSB out first.
8.5 Measuring frequency with the TEA5880TS
The three frequencies: IF, stereo decoder clock and FM can be measured by using the
counter register and a software timing window. This is achieved as follows:
1. Select the output to be measured (control register A, OUTPUT_SELECT bits, select
OS_STEREO_DEC, OS_IF_OSC or OS_FM_OSC output)
2. Enable measure mode (clear EN_MEAS# bit of control register A)
3. Reset the counter (control register B, CNT_RST bit, pulse HIGH-to-LOW transition)
4. Start the counter on the TEA5880TS (control register B, set CNT1_EN bit); at the
moment the R/W signal goes LOW the counter starts
5. Wait time t
6. To stop the counter, first set the R/W signal HIGH, then disable the counter in the
TEA5880TS (control register B, clear CNT1_EN bit)
7. Read the pulse count n from the counter register of the TEA5880TS
8. Restore the measure mode
9. Restore the output select bits.
Note: The measuring window begins at the moment the R/W signal is driven LOW (point
4) and ends when the R/W signal is driven HIGH (point 6).

Philips Semiconductors
Integrated FM stereo radio IC for host processor tuning
The IF and stereo decoder frequency can be calculated using the equation f = n/t, and the
FM frequency can be calculated using the equation f = (n/t) x 256.
Note: The precision of ‘f’ depends on the following:
• The duration of t. 1 pulse wrong at t = 1 ms results in more deviation than at t = 32 ms
• The precision of the measuring window: calculate with t = 32 ms gives other ‘f’ values
than with t = 32 ms. In the application care should be taken to have an accurate
measuring window t.
8.6 Initialize the TEA5880TS
After power-up, the TEA5880TS needs to be initialized as follows:
• Control register A: STE_PMUTE = 1; DEM_PMUTE = 1; AMUTE = 1; FM = 1; other
bits = 0
• Control register B: CNT_RST = 1; PISO_CLR = 1; MONO = 1; DEEMP = 1 (for
Europe); Bit [8:6] = 100b; other bits = 0
• Control register C: All bits = 0
• VADC register: VADC1 = 26 (decimal), this value should not be changed hereafter;
VADC2 = 18 (decimal), this value should not be changed hereafter
• Calibrate the IF frequency at 110 kHz
• Calibrate the stereo decoder clock at 37.5 kHz (to reduce the initialization time,
calibration of the stereo decoder clock can be postponed until the stereo mode is
selected).

14. Printed-circuit board layout for SSOP24 package
The printed-circuit board traces from LL1 to VCC1 and from VCC1 to LR1 as shown in
Figure 10, are to create two inductors, each of approximately 38 nH. These inductors,
together with internal capacitors, form part of the LC oscillator to determine the FM tuning
band. If the value of the inductors becomes much greater than 38 nH, the whole FM
tuning band (normally from 76 MHz to 108 MHz) will be shifted lower. If the value of the
inductors becomes much smaller than 38 nH, the whole FM tuning band (normally from
76 MHz to 108 MHz) will be shifted higher.
If the layout of the two inductance traces is not preferred, two SMD inductors can be used
to replace the two printed-circuit board inductance traces as an alternative. The layout of
the two SMD inductors should be as close to the pins as possible.

Integrated FM stereo radio IC for host processor tuning
17. Soldering
17.1 Introduction to soldering surface mount packages
This text gives a very brief insight to a complex technology. A more in-depth account of
soldering ICs can be found in our Data Handbook IC26; Integrated Circuit Packages
(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface mount IC packages. Wave
soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is recommended.
17.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and
binding agent) to be applied to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement. Driven by legislation and
environmental forces the worldwide use of lead-free solder pastes is increasing.
Several methods exist for reflowing; for example, convection or convection/infrared
heating in a conveyor type oven. Throughput times (preheating, soldering and cooling)
vary between 100 and 200 seconds depending on heating method.
Typical reflow peak temperatures range from 215 to 270 °C depending on solder paste
material. The top-surface temperature of the packages should preferably be kept:
• below 225 °C (SnPb process) or below 245 °C (Pb-free process)
– for all BGA, HTSSON..T and SSOP..T packages
– for packages with a thickness ≥ 2.5 mm
– for packages with a thickness < 2.5 mm and a volume ≥ 350 mm3 so called
thick/large packages.
• below 240 °C (SnPb process) or below 260 °C (Pb-free process) for packages with a
thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages.
Moisture sensitivity precautions, as indicated on packing, must be respected at all times.
17.3 Wave soldering
Conventional single wave soldering is not recommended for surface mount devices
(SMDs) or printed-circuit boards with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering method was specifically
developed.
If wave soldering is used the following conditions must be observed for optimal results:
• Use a double-wave soldering method comprising a turbulent wave with high upward
pressure followed by a smooth laminar wave.
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be
parallel to the transport direction of the printed-circuit board;

Philips Semiconductors
Integrated FM stereo radio IC for host processor tuning
– smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the
transport direction of the printed-circuit board.
The footprint must incorporate solder thieves at the downstream end.
• For packages with leads on four sides, the footprint must be placed at a 45° angle to
the transport direction of the printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
During placement and before soldering, the package must be fixed with a droplet of
adhesive. The adhesive can be applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the adhesive is cured.
Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 °C or
265 °C, depending on solder material applied, SnPb or Pb-free respectively.
A mildly-activated flux will eliminate the need for removal of corrosive residues in most
applications.
17.4 Manual soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage
(24 V or less) soldering iron applied to the flat part of the lead. Contact time must be
limited to 10 seconds at up to 300 °C.
When using a dedicated tool, all other leads can be soldered in one operation within
2 to 5 seconds between 270 and 320 °C.

[1] For more detailed information on the BGA packages refer to the (LF)BGA Application Note (AN01026);
order a copy from your Philips Semiconductors sales office.
[2] All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the
maximum temperature (with respect to time) and body size of the package, there is a risk that internal or
external package cracks may occur due to vaporization of the moisture in them (the so called popcorn
effect). For details, refer to the Drypack information in the Data Handbook IC26; Integrated Circuit
Packages; Section: Packing Methods.
[3] These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no
account be processed through more than one soldering cycle or subjected to infrared reflow soldering with
peak temperature exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package
body peak temperature must be kept as low as possible.

[4] These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the
solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink
on the top side, the solder might be deposited on the heatsink surface.
[5] If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave
direction. The package footprint must incorporate solder thieves downstream and at the side corners.
[6] Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
[7] Wave soldering is suitable for SSOP, TSSOP, VSO and VSOP packages with a pitch (e) equal to or larger
than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
[8] Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered
pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by
using a hot bar soldering process. The appropriate soldering profile can be provided on request.
[9] Hot bar soldering or manual soldering is suitable for PMFP packages.
