VSP1021PFBG4

Overview

The VSP1021PFBG4 is a monolithic analog-signal processor and digitizer designed for area charge-coupled-device (CCD) sensors. It integrates input clamp circuitry, correlated double sampling, and a programmable-gain amplifier with a 0-dB to 36-dB range in CCD mode. The device features a 10-bit pipeline ADC operating at 25 MSPS for CCD applications and 28 MSPS for video mode. It operates on a single 2.7-V to 3.3-V supply, consuming 95 mW normally and 1 mW in power-down mode. The component is housed in a 48-terminal TQFP package and functions within an operating temperature range of –20°C to 75°C.

Feature Summary

• Integrated 10-bit pipeline ADC with 25-MSPS throughput for CCD mode and 28-MSPS for video mode
• Programmable-gain amplifier providing 0-dB to 36-dB gain range in CCD mode and 0-dB to 12-dB in video mode
• Dual internal DACs for automatic or programmable optical-black-level and offset calibration
• Serial interface for register configuration and parallel data port for microprocessor communication

Applications

• Digital still cameras
• Digital camcorders
• Digital video cameras

Procurement Notes

Verify the marketing status before procurement, as the VSP1021PFBG4 is classified as Not Recommended For New Designs (NRND). This designation indicates the device is in production only to support existing customers and is not recommended for new designs. Confirm availability through authorized distributors and ensure compliance with RoHS and lead-free specifications defined by the G4 suffix.

Selection Notes

Select this component when interfacing directly with CCD sensors requiring integrated signal conditioning and digitization. Ensure the application utilizes a single 3-V power supply compatible with the 2.7-V to 3.3-V operating range. Verify that the required gain settings fit within the specified 0-dB to 36-dB range for CCD mode. Confirm that the 48-terminal TQFP package dimensions align with the PCB layout constraints.

Part Context

The VSP1021PFBG4 belongs to Texas Instruments' Video and Imaging product line, specifically categorized under Data Converters. It serves as a specialized solution for electronic video-camcorder applications where high throughput and low power consumption are critical. The device consolidates multiple analog processing functions into a single monolithic CMOS chip, reducing the component count required for CCD sensor interfaces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the device is marked Not Recommended For New Designs, alternative components must be identified based on specific functional requirements such as ADC resolution, sampling rate, and PGA gain ranges.
