Description

The HD49323AF-01 is a CMOS IC that provides CCD-AGC analog processing (CDS/AGC) suitable for

CCD camera digital signal processing systems together with a 10-bit A/D converter in a single chip.

Functions

• Correlated Double Sampling

• AGC

• Sample hold

• Offset compensation

• Serial interface control

• 10-bit ADC

• 3 V single operation (2.7 V to 3.6 V)

• Power dissipation: 198 mW (Typ)

• Maximum frequency: 20 MHz (Min)

Features

• Good suppression of CCD output low-frequency noise is achieved through the use of S/H type

correlated double sampling.

• A high S/N ratio is achieved through the use of a AGC type amplifier, and high sensitivity is provided

by a wide cover range.

• An auto offset circuit provides compensation of output DC offset voltage fluctuations due to variations

in AGC amplifier gain.

• AGC, standby mode, offset control, etc., is possible via a serial interface.

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

• Version of Hitachi’s previous-generation HD49322BF with improved functions and performance,

including in particular an approximately 3.0 dB improvement in S/N.
