TEST1  
All logic inputs and outputs are compatible with  
TTL/CMOS levels, providing an easy connection to a  
standard microcontroller I/O port.  
FUNCTIONAL DESCRIPTION  
Both transmission and reception stages are controlled  
either by the master clock of the microcontroller or by the  
on-chip reference oscillator connected to a crystal. This  
ensures the accuracy of the transmission carrier and the  
exact trimming of the digital filter, thus making the  
performance totally independent of application  
disturbances such as component spread, temperature,  
supply drift and so on.  
The digital part of the IC is fully scan-testable. Two digital  
inputs, SCANTEST and TEST1, are used for production  
test: these pins must be left open-circuit in functional mode  
(correct levels are internally defined by pull-up or  
pull-down resistors).  
Transmission mode  
The interface with the power network is made by means of  
an LC network (see Fig.18). The device includes a power  
output stage that feeds a 120 dBµV (RMS) signal on a  
typical 30 load.  
To provide strict stability with respect to environmental  
conditions, the carrier frequency is generated by scanning  
the ROM memory under the control of the microcontroller  
clock or the reference frequency provided by the on-chip  
oscillator. High frequency clocking rejects the aliasing  
components to such an extent that they are filtered by the  
coupling LC network and do not cause any significant  
disturbance. The data modulation is applied through  
pin DATAIN and smoothly applied by specific digital circuits  
to the carrier (shaping). Harmonic components are limited  
in this process, thus avoiding unacceptable disturbance of  
the transmission channel (according to CISPR16 and  
EN50065-1 recommendations). A 55 dB Total Harmonic  
Distortion (TDH) is reached when the typical LC coupling  
network (or an equivalent filter) is used.  
To reduce power consumption, the IC is disabled by a  
power-down input (pin PD): in this mode, the on-chip  
oscillator remains active and the clock continues to be  
supplied at pin CLKOUT. For low-power operation in  
reception mode, this pin can be dynamically controlled by  
the microcontroller, see Section “Power-down mode”.  
When the circuit is connected to an external clock  
generator (see Fig.6), the clock signal must be applied at  
pin OSC1 (pin 7); OSC2 (pin 8) must be left open-circuit.  
Fig.7 shows the use of the on-chip clock circuit.

Product specification  
Home automation modem  
TDA5051A  
The DAC and the power stage are set in order to provide  
a maximum signal level of 122 dBµV (RMS) at the output.  
After digital demodulation, the baseband data signal is  
made available after pulse shaping.  
The output of the power stage (TXOUT) must always be  
connected to a decoupling capacitor, because of a DC  
level of 0.5VDD at this pin, which is present even when the  
device is not transmitting. This pin must also be protected  
against overvoltage and negative transient signals.  
The DC level of TXOUT can be used to bias a unipolar  
transient suppressor, as shown in the application diagram;  
see Fig.18.  
The signal pin (RXIN) is a high-impedance input which has  
to be protected and DC decoupled for the same reasons  
as with pin TXOUT. The high sensitivity (82 dBµV) of this  
input requires an efficient 50 Hz rejection filter (realized by  
the LC coupling network), which also acts as an  
anti-aliasing filter for the internal digital processing;  
see Fig.18.  
Data format  
Direct connection to the mains is done through an LC  
network for low-cost applications. However, a HF signal  
transformer could be used when power-line insulation has  
to be performed.  
TRANSMISSION MODE  
The data input (DATAIN) is active LOW: this means that a  
burst is generated on the line (pin TXOUT) when DATAIN  
pin is LOW.  
CAUTION  
Pin TXOUT is in a high-impedance state as long as the  
device is not transmitting. Successive logic 1s are treated  
in a Non-Return-to-Zero (NRZ) mode, see pulse shapes in  
Figs 8 and 9.  
In transmission mode, the receiving part of the circuit is  
not disabled and the detection of the transmitted signal  
is normally performed. In this mode, the gain chosen  
before the beginning of the transmission is stored, and  
the AGC is internally set to 6 dB as long as DATAIN  
is LOW. Then, the old gain setting is automatically  
restored.  
RECEPTION MODE  
The data output (pin DATAOUT) is active LOW; this means  
that the data output is LOW when a burst is received.  
Pin DATAOUT remains LOW as long as a burst is received.  
Reception mode  
The input signal received by the modem is applied to a  
wide range input amplifier with AGC (6 to +30 dB). This is  
basically for noise performance improvement and signal  
level adjustment, which ensures a maximum sensitivity of  
the ADC. An 8-bit conversion is then performed, followed  
by digital band-pass filtering, to meet the CISPR  
normalization and to comply with some additional  
limitations met in current applications.  
Power-down mode  
Power-down input (pin PD) is active HIGH; this means that  
the power consumption is minimum when pin PD is HIGH.  
Now, all functions are disabled, except clock generation.

TDA5051A  
If wave soldering is used the following conditions must be  
observed for optimal results:  
SOLDERING  
Introduction to soldering surface mount packages  
Use a double-wave soldering method comprising a  
turbulent wave with high upward pressure followed by a  
smooth laminar wave.  
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).  
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;  
There is no soldering method that is ideal for all surface  
mount IC packages. Wave soldering is not always suitable  
for surface mount ICs, or for printed-circuit boards with  
high population densities. In these situations reflow  
soldering is often used.  
– 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.  
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.  
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.  
Several methods exist for reflowing; for example,  
infrared/convection heating in a conveyor type oven.  
Throughput times (preheating, soldering and cooling) vary  
between 100 and 200 seconds depending on heating  
method.  
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 reflow peak temperatures range from  
215 to 250 °C. The top-surface temperature of the  
packages should preferable be kept below 230 °C.  
Typical dwell time is 4 seconds at 250 °C.  
A mildly-activated flux will eliminate the need for removal  
of corrosive residues in most applications.  
Wave soldering  
Manual 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.  
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.  
To overcome these problems the double-wave soldering  
method was specifically developed.  
When using a dedicated tool, all other leads can be  
soldered in one operation within 2 to 5 seconds between  
270 and 320 °C.

Notes  
1. 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”.  
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink  
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).  
3. 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.  
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;  
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.  
5. Wave soldering is only suitable for SSOP and TSSOP 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.
