Product details
Overview
VSP2262Y from Texas Instruments is a complete mixed-signal CCD signal processor IC for digital cameras, integrating correlated double sampling (CDS), programmable gain amplifier (–6 dB to +42 dB), 12-bit analog-to-digital conversion at up to 20 MHz, 79 dB SNR, and operation from a single 2.7 V to 3.6 V supply in an LQFP-48 package.
For engineers reviewing the VSP2262Y datasheet, VSP2262Y pinout, VSP2262Y application, or VSP2262Y equivalent, key selection considerations include its dedicated CCD signal chain architecture, black level clamping accuracy, stand-by power consumption (6 mW), and compatibility with optical black (OB) pixel calibration in portable imaging systems.
Technical Context
The VSP2262Y implements a full analog front-end for CCD sensors, featuring CDS with input clamping and offset correction, digitally controlled PGA with linear-in-dB gain response, and a high-fidelity 12-bit ADC with no missing codes. Its timing control supports preblanking and optical black level sampling via dedicated pins (PBLK, COB, CLPOB).
It integrates reference voltage generation, serial interface (SCLK/SDATA/SLOAD), reset and clock inputs (RESET, ADCCK, SHP, SHD), and dual power domains (DRVDD/DRVGND and GNDA) to isolate analog and digital noise-critical for maintaining 79 dB SNR in low-voltage portable camera designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | 12-bit with no missing codes ensures monotonicity and precision in digitizing CCD analog video output. |
| Conversion Rate | Up to 20 MHz enables real-time capture of high-frame-rate interlaced or progressive CCD outputs. |
| PGA Gain Range | –6 dB to +42 dB digitally programmable gain accommodates wide illumination dynamic range without external amplification. |
| Signal-to-Noise Ratio | 79 dB SNR preserves image fidelity during low-light CCD readout and analog signal conditioning. |
| Supply Voltage | 2.7 V to 3.6 V single-supply operation simplifies power design for battery-powered digital cameras. |
| Stand-by Power | 6 mW stand-by mode reduces system-level power during idle or preview states in portable imaging devices. |
Pinout & Package
VSP2262Y is housed in a 48-pin LQFP (PT drawing) package with exposed thermal pad, RoHS-compliant green finish (CU NIPDAU), MSL Level-1 rating, and 0.5 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CCDIN | CCD Analog Input | Primary differential input for CCD video signal; connects directly to sensor output with CDS processing path. |
| PBLK, COB, CLPOB | Optical Black Control | Supports OB pixel sampling and black level clamping for accurate DC offset removal and fixed-pattern noise suppression. |
| SHP, SHD, SLOAD | Timing Control Inputs | Accept CCD horizontal/vertical sync and load signals to synchronize CDS, PGA, and ADC sampling windows. |
| ADCCK, RESET | ADC Clock & System Reset | ADCCK drives internal conversion timing; RESET initializes internal registers and analog blocks on power-up or error recovery. |
| B[11:0] | Digital Output Bus | 12-bit parallel CMOS output bus delivering digitized video data synchronized to ADCCK and latch timing. |
Key Features
| Feature | Design Value |
|---|---|
| Correlated Double Sampling (CDS) | Removes reset noise and kTC noise from CCD output, enabling clean video signal extraction before amplification. |
| Black Level Clamping Recovery | Fast black level recovery after PGA gain change maintains consistent DC reference across exposure/gain transitions. |
| Linear-in-dB PGA Control | Ensures predictable, repeatable gain adjustment steps for auto-exposure algorithms without logarithmic interpolation. |
| Integrated Reference Generator | On-chip REFN/REFP and CM pins provide stable, low-noise references for CDS and ADC-reducing external component count. |

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 | 16-bit ADC, 20 MSPS, but lacks integrated CDS and black level clamping circuitry; requires external support components. | Targeted at high-end scientific imaging where resolution >12-bit is critical; not optimized for portable power or OB-based calibration. | Select AD9826ASTZ only when higher resolution and external timing control flexibility outweigh integration and power advantages of VSP2262Y. |
| TDC1000 | Ultrasonic AFE, not a CCD processor; no CDS, PGA, or OB support; incompatible signal chain architecture. | Designed for time-of-flight ultrasonic sensing-not applicable to CCD video signal paths. | VSP2262Y remains the only suitable option among these for CCD-based imaging; TDC1000 is not a functional alternative. |
Compared with AD9826ASTZ and TDC1000, the VSP2262Y delivers fully integrated, power-optimized CCD signal processing-including CDS, OB clamping, and linear-in-dB PGA-in a single LQFP-48 device, whereas alternatives either require external circuitry or serve entirely different sensing modalities.

FAQ
What is the primary function of the VSP2262Y in a digital camera system?
The VSP2262Y serves as a complete analog front-end and ADC for CCD sensors, performing correlated double sampling (CDS), programmable gain amplification (–6 dB to +42 dB), optical black level clamping, and 12-bit digitization at up to 20 MHz. Its integrated architecture eliminates the need for discrete CDS and PGA stages, making it central to image quality and power efficiency in compact digital camera designs using the VSP2262Y.
Does the VSP2262Y support optical black (OB) pixel calibration?
Yes, the VSP2262Y explicitly supports optical black pixel calibration through dedicated pins PBLK, COB, and CLPOB, enabling automatic black level clamping and offset correction. This functionality is confirmed in the device description and block diagram, and is essential for achieving accurate DC restoration and fixed-pattern noise reduction in CCD-based imaging systems using the VSP2262Y.
What is the operating voltage range and power consumption of the VSP2262Y?
The VSP2262Y operates from a single supply of 2.7 V to 3.6 V, with typical power consumption of 83 mW at 3.0 V and 6 mW in stand-by mode. These values are specified in the FEATURES section and align with its target use in battery-powered portable imaging equipment where low-voltage operation and power budgeting are critical design constraints for the VSP2262Y.
Is the VSP2262Y pin-compatible with other members of the VSP226x family?
No documented pin compatibility exists between the VSP2262Y and other VSP226x variants such as VSP2261 or VSP2263. The datasheet provides no pinout comparison or migration guidance, and the VSP2262Y's LQFP-48 package and specific feature set (e.g., OB clamping implementation) are not stated as shared across the family. Engineers must treat the VSP2262Y as a standalone part requiring dedicated layout and validation.
Why is the VSP2262Y marked as "Not Recommended For New Designs" (NRND)?
The VSP2262Y is designated NRND by Texas Instruments per its 2014 Packaging Addendum, indicating it remains in production to support existing customers but is not recommended for new designs due to obsolescence planning. This status reflects TI's strategic shift toward newer CMOS image sensor interfaces and digital back-end solutions; however, the VSP2262Y continues to be supported with full datasheet documentation and traceable sourcing for legacy CCD-based systems relying on the VSP2262Y.
