Product details
Overview
VSP2262Y/2K from Texas Instruments is a mixed-signal CCD signal processor IC for digital cameras, integrating correlated double sampling (CDS), programmable gain amplifier (–6 dB to +42 dB), 12-bit ADC with 20 MHz conversion rate, 79 dB SNR, and operates from 2.7 V to 3.6 V single supply.
For engineers reviewing the VSP2262Y/2K datasheet, VSP2262Y/2K pinout, VSP2262Y/2K application, or VSP2262Y/2K equivalent, this device serves as a complete analog front-end for CCD image sensors in portable imaging systems requiring low-power, high-SNR signal conditioning and digitization.
Technical Context
The VSP2262Y/2K implements a dedicated CCD signal chain: CDS extracts pixel video while rejecting reset noise; digitally controlled PGA provides linear-in-dB gain adjustment across illumination conditions; black level clamping uses optical black (OB) pixels for accurate DC restoration.
It features on-chip reference voltage generation, preblanking timing control, serial interface for configuration, and latched 12-bit parallel digital output. The architecture supports fast black level recovery after gain changes and includes input clamp, offset correction, and stable analog signal paths optimized for CCD sensor outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCD signal processing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9826ASTZ | 14-bit ADC, 25 MSPS, requires external reference and clock; no integrated CDS or OB clamping. | Used in higher-resolution scientific imaging where external timing control is preferred. | Choose AD9826ASTZ when higher resolution and external flexibility outweigh integration benefits of VSP2262Y/2K. |
| TDC1000 | Ultrasonic AFE, not CCD-optimized; lacks CDS, OB clamping, and CCD-specific timing controls. | Designed for time-of-flight sensing, not optical image capture. | Not functionally equivalent; only consider TDC1000 if migrating to ultrasonic sensing architecture. |
Compared with AD9826ASTZ and TDC1000, the VSP2262Y/2K uniquely integrates CDS, OB clamping, and CCD-timed PGA in a single 48-pin LQFP, eliminating external timing logic and reference circuitry required by alternatives.

FAQ
What is the primary function of the VSP2262Y/2K in a digital camera system?
The VSP2262Y/2K serves as the complete analog front-end for CCD sensors, performing correlated double sampling (CDS), programmable gain amplification (–6 dB to +42 dB), optical black clamping, and 12-bit analog-to-digital conversion. Its integrated architecture eliminates the need for discrete CDS and ADC stages, making it central to image quality and power efficiency in compact digital cameras.
Is the VSP2262Y/2K pin-compatible with other members of the VSP226x family?
Yes, the VSP2262Y/2K shares the same LQFP-48 package and pinout as the base VSP2262Y, including identical signal assignments for CCDIN, B[11:0], SHP, SCLK, and power terminals. This allows direct substitution within existing PCB layouts designed for the VSP2262Y, provided firmware and timing configurations remain consistent.
Does the VSP2262Y/2K support both progressive and interlaced CCD sensors?
The VSP2262Y/2K is optimized for interline-transfer CCD sensors with standard preblanking and optical black timing requirements. It does not natively support frame-transfer or full-frame CCD architectures requiring extended vertical blanking or dual-output timing, and its timing control logic is not configurable for interlaced field sequencing.
What is the significance of "NRND" status for the VSP2262Y/2K?
"NRND" (Not Recommended for New Designs) indicates that Texas Instruments no longer promotes the VSP2262Y/2K for new projects but continues manufacturing to support existing customer designs. Aetrix Electronics maintains active inventory and supply chain continuity for the VSP2262Y/2K, including traceable lots and lifecycle coordination for ongoing production needs.
Can the VSP2262Y/2K operate from a 2.5 V supply?
No, the VSP2262Y/2K has a specified minimum supply voltage of 2.7 V per its absolute maximum ratings and functional operation limits. Operation below 2.7 V may result in degraded CDS performance, incomplete ADC code coverage, or failure to meet the 79 dB SNR specification. Systems must maintain VCC within 2.7 V to 3.6 V for guaranteed VSP2262Y/2K functionality.
