Description

The HD49335NP/HNP 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.

There are address map and timing generator charts besides this specification. May be contacted to our sales department

if examining the details.

Functions

• Correlated double sampling

• PGA

• Serial interface control

• 10-bit ADC

• Timing generator

• Operates using only the 3 V voltage

• Corresponds to switching mode of power dissipation and operating frequency

Power dissipation: 220 mW (Typ), maximum frequency: 36 MHz (HD49335HNP)

Power dissipation: 150 mW (Typ), maximum frequency: 25 MHz (HD49335NP)

• ADC direct input mode

• QFN 64-pin package

Features

• Suppresses low-frequency noise, which output from CCD by the correlated double sampling.

• The S/H response frequency characteristics for the reference level can be adjusted using values of external parts and

registers.

• High sensitivity is achieved due to the high S/N ratio and a wide dynamic range provided by a PG amplifier.

• PGA, pulse timing, standby mode, etc., is achieved via a serial interface.

• High precision is provided by a 10-bit-resolution A/D converter.

• Difference encoded gray code can be selected as an A/D output code. It is effective in suppression of solarization

(wave pattern). It is patented by Renesas.

• Timing generator generates the all of pulse which are needed for CCD driving.
