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 SPBLK pulse, buffered by the SHAMP, then provided to the CDSAMP. The signal level is directly sampled at C2 by using the SPSIG pulse, and 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 SPBLK pulse validation period. During the PBLK period, the above sampling and bias operation are paused. Rev.1.0, Apr.05.2004, page 6 of 19 HD49330AF/AHF 2. PGA Circuit The PGAMP is the programmable gain amplifier for the latter stage. The PGAMP and the CDSAMP set the gain using 10 bits of register. The equation below shows how the gain changes when register value N is from 0 to 1023. In CDSIN mode: Gain = (-2.36 dB + 0.033 dB) x N (LOG linear). In ADCIN mode: Gain = (0.57 times + 0.00446 times) x 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 Setting The DAC DC voltage added to the output of the PGAMP is adjusted by automatic offset calibration. The data, which cancels the output offset of the PGAMP and the input offset of the ADC, and the clamp data (56 LSB to 304 LSB) set by register are added and input to the DAC. The automatic offset calibration starts automatically after the RESET mode set by register 1 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 x C3) (fclk: ADCLK frequency, C3: SHAMP external feedback capacitor) Example: When fclk = 20 MHz and C3 = 1.0 F, 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 64 LSB, the high-speed lead-in operation continues, and when the offset error is 64 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. See table 2.

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 (56 to 304 LSB).

Rev.1.0, Apr.05.2004, page 16 of 19 HD49330AF/AHF 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 F or more and an electrolytic capacitor of 10 F 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. Analog +3.0V Digital +3.0V Noise filter AVDD DVDD HD49330AF/AHF AVSS DVSS Noise filter DVDD Example of noise filter AVDD HD49330AF/AHF DVSS 100 H 0.01 F 0.01 F AVSS 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 16).
