GENERAL DESCRIPTION
The TDA9952 is a 10-bit analog-to-digital interface for CCD cameras. The device consists of a Correlated Double Sampling (CDS) circuit, a digitally Programmable Gain Amplifier (PGA), a black level clamp and a 10-bit Analog-to-Digital Converter (ADC).
An internal CDS input buffer is incorporated in order to avoid using an external buffer that would consume more power and therefore optimizing the application for low noise, low power working.
The PGA gain, the ADC clamp level and other settings are controlled via a 3-wire serial digital interface.
An additional DAC is provided for system controls.
The TDA9952 operates from a single 3 V power supply (2.7 V minimum) and dissipates 135 mW (typical value).

FEATURES
*Sample rate = 25 Msps;10-bit resolution
*Single 3.0 V supply operation (2.2 to 3.6 V operation for the digital outputs)
*Low power consumption: only 115 mW at 2.7 V
*Power consumption in standby mode: 4.5 mW (typical value)
*Programmable gain amplifier : gain range = 36 dB in 0.1 dB steps
*Correlated double sampling
*Internal input buffer for the correlated double sampling
*Fully programmable via a 3-wire serial interface
*8-bit DAC included for external analog settings
*TTL-compatible inputs and CMOS-compatible outputs.

APPLICATIONS
*Video camcorders
*Digital still cameras
*PC-cameras.

Description
The ICX413AQ is a diagonal 28.40mm (Type 1.8) interline CCD solid-state image sensor with a square pixel array and 6.15M effective pixels. Frame readout allows all pixels' signals to be output independently within approximately 1/3.08 second. Adoption of a design specially suited for frame readout ensures a high saturation signal level.
High sensitivity and low dark current are achieved through the adoption of R, G and B primary color mosaic filters and HAD (Hole-Accumulation Diode) sensors.
This chip is suitable for applications such as electronic still cameras, etc.

Features
*Frame readout mode
*High horizontal and vertical resolution
*Square pixel
*Horizontal drive frequency: 25.0MHz
*R, G, B primary color mosaic filters on chip
*High sensitivity, low dark current
