VSP10T21PFB

Overview

The VSP10T21PFB is a 3-V, 10-bit, 21-MSPS CCD analog front end designed for digital camera and camcorder applications. It integrates a correlated double sampler (CDS), programmable gain amplifier (PGA), and pipeline ADC to process CCD signals. The device operates on a single 2.7-V to 3.3-V supply with typical power consumption of 109 mW at 2.7 V and 21 MSPS. Key electrical parameters include a full channel differential nonlinearity error of less than ±0.5 LSB and integral nonlinearity error of less than ±1.0 LSB. It features internally programmable CDS timing control and serial register configuration via a 3-wire interface.

Feature Summary

• Integrated 10-bit, 21-MSPS pipeline ADC with <±0.5 LSB DNL and <±1.0 LSB INL
• Programmable Gain Amplifier (PGA) offering 0-dB to 36-dB range in CCD mode and 0-dB to 12-dB in video mode
• Internally programmable Correlated Double Sampler (CDS) timing with adjustable SR and ADCCLK delays
• Single 3-V power supply operation with 1.5-mW power-down mode

Applications

• Digital Still Camera
• Digital Camcorder
• Digital Video Camera

Procurement Notes

Verify the specific suffix PFB corresponds to the 48-terminal TQFP package and –20°C to 75°C operating temperature range as defined in the datasheet. Confirm that the component meets standard warranty specifications per Texas Instruments documentation. Ensure compatibility with 3-Wire serial interface requirements for register configuration.

Selection Notes

Select this component for CCD signal processing requiring integrated analog front-end functions. The PGA gain resolution is 0.047 dB per step. In video mode, the input connects to terminal PIN (31) rather than the differential CCD inputs. The digital interface supply DIVDD supports 1.8 V to 3.6 V, allowing flexibility for different logic levels.

Part Context

The VSP10T21 is part of Texas Instruments' CCD analog front-end processor family. The PFB suffix indicates the 48-lead Thin Quad Flatpack (TQFP) package variant. This device replaces discrete analog processing circuits by integrating clamping, CDS, PGA, and digitization into a single CMOS chip optimized for low-power consumer imaging devices.
