VSP2262Y

Overview

The VSP2262Y is a mixed-signal CCD signal processor designed for digital camera applications. It provides complete signal conditioning and analog-to-digital conversion for CCD array outputs. The device features Correlated Double Sampling (CDS), programmable black level clamping, and a Programmable Gain Amplifier (PGA) with a gain range of -6dB to +42dB. It delivers a 12-bit digital data output at up to 20MHz conversion rate with no missing codes. Operating from a single 2.7V to 3.6V supply, it consumes 83mW typically at 3.0V.

Feature Summary

• Integrated Correlated Double Sampling (CDS) circuitry for extracting video information from pixels
• Programmable Gain Amplifier (PGA) offering linear gain control ranging from -6dB to +42dB
• Built-in black level clamping mechanism for accurate reference recovery after gain changes
• 12-bit Analog-to-Digital Converter (ADC) ensuring high-resolution digital output without missing codes

Applications

• Digital cameras requiring CCD signal processing
• Portable imaging devices needing low voltage operation
• Systems utilizing CCD arrays for image capture

Procurement Notes

Verify the current marketing status before design implementation. This component is classified as Not Recommended For New Designs (NRND). While production continues to support existing customers, Texas Instruments does not recommend its use in new designs. Ensure compatibility with legacy systems and confirm long-term availability requirements align with the NRND status.

Selection Notes

Select this component only for maintaining or upgrading existing designs that already utilize the VSP2262 architecture. Evaluate if modern alternatives offer better performance or longer lifecycle support. Consider the specific interface requirements and power constraints associated with older CCD sensors when determining suitability for the target application.

Part Context

The VSP2262Y belongs to the VSP2262 family of CCD signal processors manufactured by Texas Instruments. It is housed in an LQFP-48 package. The device integrates essential functions like CDS, PGA, and ADC into a single chip, simplifying the design of CCD-based imaging systems by reducing external component count and board space requirements.

Replacement Considerations

Texas Instruments explicitly states this part is Not Recommended For New Designs. No official substitute part numbers are provided in the documentation. Designers should consult TI's current product portfolio for newer CCD signal processors or integrated camera solutions suitable for new development projects.
