Overview
The VSP2260Y/2K is a mixed-signal CCD signal processor designed for digital camera applications. It integrates Correlated Double Sampling (CDS), a Programmable Gain Amplifier (PGA) with –6dB to +42dB range, and a 10-bit Analog-to-Digital Converter (ADC). The device operates on a single 2.7V to 3.6V supply, consuming 83mW typically at 3.0V. It supports conversion rates up to 20MHz with a 79dB signal-to-noise ratio. The component is housed in an LQFP-48 package and functions within a temperature range of –25°C to +85°C.
Feature Summary
- Integrates Correlated Double Sampling (CDS) and Optical Black level clamping for accurate video extraction.
- Features a digitally controlled Programmable Gain Amplifier (PGA) with linear dB gain adjustment.
- Includes a high-performance 10-bit pipelined ADC with no missing codes guarantee.
- Supports low-voltage portable operation with dedicated Stand-by mode for power reduction.
Applications
- Digital still cameras
- Video cameras
- Security cameras
Procurement Notes
Verify the specific ordering suffix /2K confirms the Tape and Reel packaging format containing 2000 devices per reel. Confirm the active status of the part number against current manufacturer databases, as availability may vary by region or distributor. Ensure compatibility with existing LQFP-48 footprints during procurement planning.
Selection Notes
Select this component when designing systems requiring integrated CCD signal conditioning and digitization. It is suitable for applications demanding low power consumption and compact mixed-signal processing. Consider the serial interface requirements for gain and timing configuration. Evaluate the need for external buffering based on capacitive loading constraints.
Part Context
The VSP2260 belongs to Texas Instruments' family of CCD signal processors. It serves as a complete solution for conditioning CCD array outputs, combining analog front-end processing with digital conversion. This integration reduces the component count required for digital imaging systems compared to discrete solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation.
FAQ
How is the Optical Black (OB) clamp level adjusted?
The OB clamp level is programmable via the serial interface using a 10-bit control DAC resolution, allowing adjustment from 0 to 60 LSBs.
What is the data latency in normal operation mode?
In normal operation mode, the data latency is fixed at 9 clock cycles relative to the ADCCK input.
How does the device handle power consumption during inactivity?
The VSP2260 features a Stand-by mode accessible via the serial interface that disables function blocks, reducing current consumption to approximately 1mA.
