VSP2212Y

Overview

The VSP2212Y is a mixed-signal CCD signal processor for digital cameras, providing signal conditioning and analog-to-digital conversion. It features Correlated Double Sampling (CDS), programmable black level clamping, and a Programmable Gain Amplifier (PGA) with –6 to +42dB gain ranging. The device outputs 12-bit digital data at up to 20MHz conversion rate with no missing codes and achieves a 79dB signal-to-noise ratio. It includes two on-chip general-purpose 8-bit digital-to-analog converters. Operating from a single 2.7V to 3.6V supply, it consumes 99mW typically at 3.0V and 6mW in standby mode.

Feature Summary

• Provides complete mixed-signal processing including CDS, PGA, and ADC for CCD array output
• Features a stable linear gain control with quick black level recovery after gain changes
• Includes two on-chip general-purpose 8-bit DACs for generating analog control voltages

Applications

• Digital camera systems requiring CCD signal processing
• Portable imaging devices utilizing low voltage operation
• Consumer electronics integrating CCD image sensors

Procurement Notes

Verify the current marketing status before procurement as this component may be classified as Not Recommended For New Designs or Obsolete.
