VSP2210YG4

Overview

The VSP2210YG4 is a mixed-signal CCD signal processor IC designed for digital cameras. It provides complete signal conditioning and analog-to-digital conversion for CCD array outputs. The device integrates a Correlated Double Sampler (CDS), a Programmable Gain Amplifier (PGA) with –6 to +42dB gain ranging, and a 10-bit Analog-to-Digital Converter (ADC). It operates from a single 2.7V to 3.6V supply, consuming 97mW in normal mode and 6mW in standby. The unit features two on-chip general-purpose 8-bit Digital-to-Analog Converters (DACs) and utilizes a serial interface for configuration.

Feature Summary

• Integrates Correlated Double Sampling (CDS) and programmable black level clamping for accurate video extraction.
• Includes a Programmable Gain Amplifier (PGA) offering linear dB gain control from –6dB to +42dB.
• Features a 10-bit ADC with up to 20MHz conversion rate and guaranteed no missing codes.
• Contains two general-purpose 8-bit DACs for generating analog control voltages such as CCD imager bias.

Applications

• Digital still cameras
• Video cameras
• Security cameras

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current documentation to confirm compliance status and pinout compatibility. Confirm that the LQFP-48 package marking matches the required revision. Ensure the source component is an authorized distributor to guarantee authenticity and traceability for this legacy part number.

Selection Notes

Select this component when interfacing directly with CCD imagers requiring integrated CDS and ADC functionality. It is suitable for applications needing precise black level recovery and programmable gain adjustment via serial interface. Consider the low-voltage operation and power consumption characteristics for portable or battery-operated imaging systems.

Part Context

The VSP2210 is a Burr-Brown product now under Texas Instruments. It serves as a dedicated signal processor for CCD-based imaging systems. The Y variant denotes the LQFP-48 package. This chip consolidates multiple discrete functions into a single mixed-signal IC, simplifying the design of camera signal chains.

Replacement Considerations

Check for direct substitutes within the VSP22xx family. Verify pin compatibility and register mapping if replacing with other CCD processors. No specific public substitute part numbers are confirmed in the provided datasheet.

FAQ

How is the PGA gain controlled?

The PGA gain is controlled by a 10-bit digital code entered via the serial interface, allowing linear gain ranging from –6dB to +42dB.

What is the function of the COB pin?

The COB pin connects to an off-chip capacitor to set the time constant for the Optical Black Clamp Loop, which establishes the black reference level.

Can the clock polarities be changed?

Yes, the active polarity for SHP/SHD, CLPOB, and CLPDM pulses can be configured as Active HIGH or Active LOW through the serial interface registers.
