DESCRIPTION
The VSP3010 is a complete, three-channel image
signal processor for Charge Coupled Device (CCD)
or Contact Image Sensor (CIS) systems. Each chan-
nel 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 VSP3010 provides a single-ended
sampler and a reference input. The VSP3010 is
available in a 48-lead LQFP package and operates
from 0擄C to +85擄C with a single +5V supply.
