Figure 1 CDS/PGA Functional Block Diagram
1. CDS (Correlated Double Sampling) Circuit
The CDS circuit extracts the voltage differential between the black level and a signal including the black level. The
black level is directly sampled at C1 by using the SP1 pulse, buffered by the SHAMP, then provided to the
CDSAMP.
The signal level is directly sampled at C2 by using the SP2 pulse, and then provided to CDSAMP (see figure 1).
The difference between these two signal levels is extracted by the CDSAMP, which also operates as a
programmable gain amplifier at the previous stage. The CDS input is biased with VRT (2 V). During the PBLK
period, the above sampling and bias operation are paused.
2. PGA Circuit
The PGAMP is the programmable gain amplifier for the latter stage. The PGAMP and the CDSAMP set the gain
using 8 bits of register.
The equation below shows how the gain changes when register value N is from 0 to 255.
In CDSIN mode: Gain = (–2.36 dB + 0.033 dB) × N (LOG linear).
In ADCIN mode: Gain = (0.57 times + 0.001784 times) × N (linear).
Full-scale digital output is defined as 0 dB (one time) when 1 V is input.

3. Automatic Offset Calibration Function and Black-Level Clamp Data Settings
The DAC DC voltage added to the output of the PGA amplifier is adjusted by automatic offset calibration.
The data, which cancels the output offset of the PGA amplifier and the input offset of the ADC, and the clamp data
(14 LSB to 76 LSB) set by register are added and input to the DAC.
The automatic offset calibration starts automatically after the RESET mode set by register is cancelled and
terminates after 40000 clock cycles (when fclk = 20 MHz, 2 ms).
4. DC Offset Compensation Feedback Function
Feedback is done to set the black signal level input during the OB period to the DC standard, and all offsets
(including the CCD offset and the CDSAMP offset) are compensated for.
The offset from the ADC output is calculated during the OB period, and SHAMP feedback capacitor C3 is charged
by the current DAC (see figure 1).
The open-loop differential gain (∆Gain/∆H) per 1 H of the feedback loop is given by the following equation. 1H is
the one cycle of the OBP.
∆Gain/∆H = 0.078/(fclk × C3) (fclk: ADCLK frequency, C3: SHAMP external feedback capacitor)
Example:When fclk = 20 MHz and C3 = 1.0 µF, ∆Gain/∆H = 0.0039
When the PGAMP gain setting is changed, the high-speed lead-in operation state is entered, and the feedback loop
gain is increased by a multiple of N. Loop gain multiplication factor N can be selected from 2 times, 4 times, 8
times, or 16 times by changing the register settings (see table 1). Note that the open-loop differential gain
(∆Gain/∆H) must be one or lower. If it is two or more, oscillation occurs.
The time from the termination of high-speed lead-in operation to the return of normal loop gain operation can be
selected from 1 H, 2 H, 4 H, or 8 H. If the offset error is over 16 LSB, the high-speed lead-in operation continues,
and when the offset error is 16 LSB or less, the operation returns to the normal loop-gain operation after 1 H, 2 H, 4
H, or 8 H depending on the register settings. (Refer to table 2.)

5. Pre-Blanking Function
During the PBLK input period, the CSD input operation is separated and protected from the large input signal. The
ADC digital output is fixed to clamp data (14 to 76 LSB).

Dummy Clamp
It adjusts the mis-clamp which occurs when taking the photo under the highlight conditions. (Like a sun) Normally it
woks with the OB clamp, however when black level is out of the range caused by hightlight enter to OB part, it changes
to clamp processing by dummy bit level. Resister settings are follows.
D12, D11, D10 of address H'F7 (Dummy CP)
0, 0, 0 ; OFF
D8, D8 of address H'F7 (DMCG)
The amount of feed back current can be
reduced with only dummy clamp.

At CDS_in mode: –2.36 dB + 0.132 dB × N (Log linear)
At ADC_in mode: 0.57 times + 0.01784 times × N (Times linear)
∗: Full-scale digital output is defined as 0 dB when 1 V is input.
Above PGA gain definition means input signal 1 Vp-p to CDS_in, and set N = 18 (correspond 2.36 dB), and then
PGA outputs the 2 V full-range, and also ADC out puts the full code (1023).
This mean offset gain of PGA has 6 dB – 2.36 dB = 3.64 dB, therefore it should be decided that how much dB add

Ripple (pseudo outline made by quantized error) occurres on the point which swithing the ADC output multiple bit in
parallel. When switching the several of ADC output at the same time, ripple (pseudo outline caused by miss
quantization) occurs to the image.
Differential code and gray code are recommended for this countermeasure.
Figure 10 indicates circuit block. When luminance signal changes are smoothly, the number of bit of switching digital
output bit can be reduced and easily to reduce the ripple using this function.
This function is especially effective for longer the settings of sensor more than clk = 30 kHz, and ADC output.

The following describes the above serial data transfer. For details of resistor settings are referred to serial data
function table.
(1) Resistor transfer of TG part : Wait more than 6clk after release the hardware Reset and then transfer
the necessary data to TG part.
(2) DLL data transfer of CDS part : Transfer the phase data of RG, SP1, SP2, ADCLK of CDS part.
(3) Reset=L of CDS part
(4) Reset=H of CDS part
(5) Other data of CDS part
: Transfer Reset bit = 0 of address H'F2.
: Transfer Reset bit = 1 of address H'F2. (Reset release)
: Transfer the SH_SW_fsel and other PGA.
∗ Before transfer the Reset bit = 0, TG series pulse need to be settled, so address
H'00 to H'EF of TG part and H'F4 to H7F7 of CDS part should transfer in advance.

HD49335NP/HNP
Notice for Use
1. Careful handling is necessary to prevent damage due to static electricity.
2. This product has been developed for consumer applications, and should not be used in non-consumer applications.
3. As this IC is sensitive to power line noise, the ground impedance should be kept as small as possible. Also, to
prevent latchup, a ceramic capacitor of 0.1 µF or more and an electrolytic capacitor of 10 µF or more should be
inserted between the ground and power supply.
4. Common connection of AVDD and DVDD should be made off-chip. If AVDD and DVDD are isolated by a noise filter,
the phase difference should be 0.3 V or less at power-on and 0.1 V or less during operation.
5. If a noise filter is necessary, make a common connection after passage through the filter, as shown in the figure
below.

6. Connect AVSS and DVSS off-chip using a common ground. If there are separate analog system and digital system
set grounds, connect to the analog system.
7. When VDD is specified in the data sheet, this indicates AVDD and DVDD
.
8. No Connection (NC) pins are not connected inside the IC, but it is recommended that they be connected to power
supply or ground pins or left open to prevent crosstalk in adjacent analog pins.
9. To ensure low thermal resistance of the package, a Cu-type lead material is used. As this material is less tolerant of
bending than Fe-type lead material, careful handling is necessary.
10. The infrared reflow soldering method should be used to mount the chip. Note that general heating methods such as
solder dipping cannot be used.
11. Serial communication should not be performed during the effective video period, since this will result in degraded
picture quality. Also, use of dedicated ports is recommended for the SCK and SDATA signals used in the
HD49330AF. If ports are to be shared with another IC, picture quality should first be thoroughly checked.
12. At power-on, automatic adjustment of the offset voltage generated from PGA, ADC, etc., must be implemented in
accordance with the power-on operating sequence (see page 24).
13. Ripple noise of DC/DC converter which generates the voltage of analog part should set under –50 dB with power
supply voltage.
