VSP2232Y

Overview

The VSP2232Y is a mixed-signal processing IC for digital cameras, providing signal conditioning and analog-to-digital conversion for CCD array outputs. It features Correlated Double Sampling (CDS), programmable black level clamping, and a Programmable Gain Amplifier (PGA) with -6-dB to 42-dB gain ranging. The device delivers a 10-bit digital data output at up to 36-MHz conversion rate with no missing codes and a 76-dB signal-to-noise ratio. It operates from a single 2.7-V to 3.6-V supply, consuming 130 mW typically at 3.0 V, with a standby mode of 6 mW. Available in a 48-pin LQFP package.

• Integrated Correlated Double Sampling (CDS) and programmable black level clamping for accurate video extraction
• Digitally controlled Programmable Gain Amplifier (PGA) supporting wide dynamic range illumination conditions
• High-speed 10-bit analog-to-digital conversion with stable linear gain control in decibels
• Low voltage operation with dedicated standby mode for portable camera applications

Applications

• Digital camera systems requiring CCD signal conditioning
• Portable imaging devices utilizing low power consumption
• Mixed-signal processing for optical sensor arrays

Procurement Notes

Verify the current marketing status before procurement, as this component may be classified as Not Recommended For New Designs (NRND). Confirm that the 48-pin LQFP package dimensions match your PCB footprint requirements. Ensure the design supports the specified 2.7-V to 3.6-V single supply voltage range and accounts for the typical 130 mW power dissipation during active operation.

Selection Notes

Select this component when designing systems specifically interfacing with CCD sensors requiring integrated CDS and PGA functionality. Consider the VSP2262Y if a 12-bit resolution or different pinout compatibility is required, noting their pin-to-pin relationship. Evaluate the 36-MHz maximum conversion rate against your specific frame rate and pixel clock requirements to ensure adequate performance margins.
