VSP5622RSLR

Overview

The VSP5622RSLR is a 16-bit, 70 MSPS four-channel analog front-end (AFE) designed for CCD and CMOS image sensors. It integrates sampling/hold or correlated double sampling circuits, programmable gain amplifiers, and an LED driver for brightness regulation. The device features an integrated timing generator and DAC for offset adjustment. It operates with a 1.65V to 1.95V core voltage supplied by an internal LDO and 3.0V to 3.6V I/O voltage. Data outputs are selectable in LVDS or CMOS modes. The component is housed in a 48-pin HVQCCN package.

Feature Summary

• Four independent 16-bit ADC channels supporting 2, 3, or 4 channel configurations
• Integrated timing generator for sensor control and built-in LED driver
• Programmable gain amplifier for pixel-level offset correction
• Selectable LVDS or CMOS digital output interface

Applications

• Multi-output charge-coupled device (CCD) sensor systems
• Complementary metal-oxide-semiconductor (CMOS) sensor arrays
• High-speed imaging equipment requiring precise analog front-end processing

Procurement Notes

Verify the specific suffix 'RSLR' against the manufacturer's official datasheet to confirm the tape-and-reel packaging and commercial temperature range (0°C to 85°C). Ensure compatibility with the required 3.3V typical power supply and verify that the 48-pin QFN footprint matches the design layout. Confirm RoHS compliance status through the latest production documentation.

Selection Notes

Select this component when a high-speed, multi-channel AFE is required for CCD or CMOS sensors. It is suitable for designs needing integrated timing generation and LED driving capabilities without external discrete components. Consider the 48-pin package size and the specific voltage requirements (1.65V–1.95V core, 3.0V–3.6V I/O) during PCB layout and power budgeting.

Part Context

The VSP5622RSLR belongs to the VSP562x family, which includes variants like the VSP5620 and VSP5621. These devices share similar architectures but may differ in channel counts or specific feature sets. The VSP5622 specifically offers four full channels at 70 MSPS. This series is positioned as a high-performance solution for professional imaging applications requiring low noise and high dynamic range.

Replacement Considerations

The VSP5621RSLR is a related part within the same family. Verify if the application requires all four channels or if a lower channel count variant is sufficient. Cross-reference pinouts and electrical specifications with the official Texas Instruments comparison documents before substitution.
