VSP2262Y/2K

VSP2262 VSP 226 2 www.ti.com CCD SIGNAL PROCESSOR for DIGITAL CAMERAS FEATURES DESCRIPTION ● CCD SIGNAL PROCESSING: Correlated Double Sampling (CDS) Programmable Black Level Clamping ● PROGRAMMABLE GAIN AMPLIFIER (PGA): –6dB to +42dB Gain Ranging The VSP2262 is a complete mixed-signal processing IC for digital cameras, providing signal conditioning and Analog-to-Digital (A/D) conversion for the output of a CCD array. The primary CCD channel provides Correlated Double Sampling (CDS) to extract video information from the pixels, –6dB to +42dB gain range with digital control for varying illumination conditions, and black level clamping for an accurate black level reference. Input signal clamping and offset correction of the input CDS are also performed. The stable gain control is linear in dB. Additionally, the black level is quickly recovered after gain change. The VSP2262Y is available in an LQFP-48 package and operates from a single +3V/+3.3V supply. ● 12-BIT DIGITAL DATA OUTPUT: Up to 20MHz Conversion Rate No Missing Codes ● 79dB SIGNAL-TO-NOISE RATIO ● PORTABLE OPERATION: Low Voltage: 2.7V to 3.6V Low Power: 83mW (typ) at 3.0V Stand-By Mode: 6mW CLPDM SHP SHD RESET SLOAD SCLK SDATA ADCCK DRVDD VCC Serial Interface Input Clamp Correlated Double Sampling (CDS) CCDIN CCD Output Signal Timing Control Preblanking PBLK Programmable Gain Amplifier (PGA) Optical Black (OB) Level Clamping COB Copyright © 2000, Texas Instruments Incorporated CLPOB AnalogtoDigital Converter –6dB to +42dB Output Latch 12-Bit Digital Output B[11:0] Reference Voltage Generator BYPP2 BYP SBMS011 BYPM REFN CM REFP DRVGND GNDA Printed in U.S.A.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
