Description
The HD49351BP/HBP is a CMOS IC that provides CDS-PGA analog processing (CDS/PGA) suitable for CCD camera
digital signal processing systems together with a 10-bit A/D converter and timing generator in a single chip. HD49351
has deleted the stripe mode, pd_mix mode, and added the 5 – 6 pulse and H_msk2 - 4 as contrasted with HD49335.
There are address map and timing generator charts besides this specification. May be contacted to our sales department
if examining the details.

Internal Functions
Functional Description
• CDS input
 CCD low-frequency noise is suppressed by CDS (correlated double sampling).
 The signal level is clamped at 14 LSB to 76 LSB (set by resister: 5 bit 2 LSB step controls) during the OB
period. *1
 Gain can be adjusted using 8 bits of register (0.132 dB steps) within the range from –2.36 dB to 31.40 dB. *2
• ADC input
 The center level of the input signal is clamped at 512 LSB (Typ).
 Gain can be adjusted using 8 bits of register (0.01784 times steps, register settings) within the range from 0.57
times (–4.86 dB) to 5.14 times (14.22 dB). *2
• Automatic offset calibration of PGA and ADC
• DC offset compensation feedback for CCD and CDS
• Pre-blanking
 Digital output is fixed at clamp level
• Digital outputs enable function
Note: 1. It is not covered by warranty when 14 LSB settings
2. Full-scale digital output is defined as 0 dB (one time) when 1 V is input.

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 + 0.132 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 40,000 clock cycles (when fclk = 40.0 MHz, 1.0 ms, fclk = 20.0 MHz, 2.0 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
DC offset compensation per 1 H (LSB) = 0.0039 × Offset error (LSB)
Note: There is a maximum value in the above-mentioned amount of offset errors.
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 4 times, 8 times, 16
times, or 32 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 CDS input operation is separated and protected from the large input signal. The
ADC digital output is fixed to clamp data (14 to 76 LSB).

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.

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 outputs 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

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
: Transfer Reset bit = 0 of address H'F2.
(4) Reset=H of CDS part
: Transfer Reset bit = 1 of address H'F2. (Reset release)
(5) Other data of CDS part
: 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.

Values are sensor CLK = when 18 MHz.
HD49351BP/HBP
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 23).
13. Ripple noise of DC/DC converter which generates the voltage of analog part should set under –50 dB with power
supply voltage.
