VSP2232Y/2KG4

 SLAS320 − MAY 2001           FEATURES D CCD Signal Processing D D D D DESCRIPTION The VSP2232 is a complete mixed-signal processing IC for digital cameras that provides signal conditioning and analog-to-digital conversion for the output of a CCD array. The primary CCD channel provides correlated double sampling (CDS) to extract the video information from the pixels, a −6-dB to 42-dB gain with digital control for varying illumination conditions, and black level clamping for an accurate black level reference. − Correlated Double Sampling (CDS) − Programmable Black Level Clamping Programmable Gain Amplifier (PGA) − −6-dB to 42-dB Gain Ranging 10-Bit Digital Data Output − Up to 36-MHz Conversion Rate − No Missing Codes 76-dB Signal-to-Noise Ratio Portable Operation − Low Voltage: 2.7 V to 3.6 V − Low Power: 130 mW (typ) at 3.0 V − Standby Mode: 6 mW Input signal clamping and offset correction of the input CDS is also performed. The stable gain control is linear in dB. Additionally, the black level is quickly recovered after gain change. The VSP2232Y is pin-to-pin compatible with the VSP2262Y (12-bit 20 MHz) one-chip product. The VSP2232Y is available in a 48-pin LQFP package and operates from a single 3-V/3.3-V supply.

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
