The VSP3000 is a complete, three-channel image signal processor for Charge Coupled Device (CCD) or Contact Image Sensor (CIS) systems. Each channel contains sensor signal sampling, Black Level adjustment and a programmable gain amplifier. The three inputs are multiplexed into a high speed, 12-bit analog-to-digital converter. Input circuitry can be configured, by digital command, for CCD or CIS sensors. A Black Clamp and Correlated Double Samplers (CDS) are provided for CCD sensors. For CIS devices, the VSP3000 provides a single-ended sampler and a reference input. The VSP3000 is available in a 48-lead LQFP package and operates from 0C to +85C with a single +5V supply.
