VSP2210Y

Overview

The VSP2210Y is a mixed-signal CCD signal processor IC designed for digital cameras. It provides signal conditioning and analog-to-digital conversion for CCD array outputs. The device features a Correlated Double Sampler (CDS), a Programmable Gain Amplifier (PGA) with –6 to +42dB gain range, and a 10-bit Analog-to-Digital Converter (ADC) operating at up to 20MHz. It includes two general-purpose 8-bit Digital-to-Analog Converters (DACs). The unit operates on a single 2.7V to 3.6V supply, consuming 97mW in normal mode and 6mW in standby. It is housed in an LQFP-48 package.

Feature Summary

• Integrated Correlated Double Sampling (CDS) circuitry for noise reduction and video information extraction from CCD signals.
• Digitally controlled Programmable Gain Amplifier (PGA) providing linear gain ranging from –6dB to +42dB.
• Built-in Optical Black level clamp loop for accurate black reference recovery and offset correction.
• On-chip dual 8-bit Digital-to-Analog Converters (DACs) for generating analog control voltages.

Applications

• Digital still cameras
• Video cameras
• Security cameras

Procurement Notes

Verify the specific ordering suffix when sourcing components. The base model VSP2210Y is available in tray packaging, while the VSP2210Y/2K variant is supplied in tape and reel format containing 2000 devices per reel. Confirm that the received part matches the required package type and quantity specifications before integration into production workflows.

Selection Notes

Select this component for applications requiring integrated CCD signal processing with low-voltage operation. Ensure the system design accommodates the 2.7V to 3.6V supply range and the LQFP-48 thermal characteristics. Verify compatibility with the serial interface timing requirements for PGA gain and clock polarity configuration. Consider the fixed data latency of nine clock cycles during normal operation when designing the host processor synchronization logic.

Part Context

The VSP2210Y belongs to the Burr-Brown Texas Instruments family of CCD signal processors. It serves as a complete solution for digitizing CCD imager outputs by combining analog front-end conditioning with high-resolution conversion. This integration reduces the component count and board space required for digital imaging systems compared to discrete solutions.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material.

FAQ

How is the active polarity of the sampling pulses configured?

The active polarity for SHP, SHD, CLPOB, and CLPDM can be selected via the serial interface. The default setting after power-on is Active LOW, but this must be explicitly set or reset using the RESET pin.

What is the function of the PBLK input pin?

The Preblanking (PBLK) input disconnects the CCDIN signal from the internal CDS stage when driven LOW. This prevents large transient signals during blanking intervals from overdriving the device and causing saturation.

How does the device handle power consumption during idle periods?

The VSP2210 supports a Stand-By mode accessible via the serial interface. In this mode, all functional blocks are disabled, reducing power consumption to 6mW, though it requires approximately 200ms to 300ms to power up again.
