TDA9964

12-bit, 3.0 V, 30 Msps analog-to-digital interface for CCD
cameras

Rev. 03 — 16 January 2001

Objective specification

Description

The TDA9964 is a 12-bit analog-to-digital interface for CCD cameras. The device
includes a correlated double sampling circuit, PGA, clamp loops and a low-power
12-bit ADC together with its reference voltage regulator.

The PGA gain and the ADC input clamp level are controlled via the serial interface.

An additional DAC is provided for additional system controls; its output voltage range
is 1.0 V p-p, which is available at pin OFDOUT.

Features

■

Correlated Double Sampling (CDS), Programmable Gain Amplifier (PGA), 12-bit
Analog-to-Digital Converter (ADC) and reference regulator included

■

Fully programmable via a 3-wire serial interface

■

Sampling frequency up to 30 MHz

■

PGA gain range of 24 dB (in steps of 0.1 dB)

■

Low power consumption of only 175 mW at 2.7 V

■

Power consumption in standby mode of 4.5 mW (typ.)

■

3.0 V operation and 2.5 to 3.6 V operation for the digital outputs

■

All digital inputs accept 5 V signals

■

Active control pulses polarity selectable via serial interface

■

8-bit DAC included for analog settings

■

TTL compatible inputs, CMOS compatible outputs.

Applications

■

Low-power, low-voltage CCD camera systems.
