DESCRIPTION
The VSP5010 is a complete application-specific
standard product (ASP) for charge-coupled device
(CCD) line sensor applications such as copiers,
scanners, and facsimiles. The VSP5010 provides two
independent line-processing channels, and performs
analog front-end (AFE) data processing and
analog-to-digital conversion. Each channel features
correlated
double
sampling
(CDS)
and
sample-and-hold (S/H) processing stages, 14
analog-to-digital converter (ADC) blocks, a digital
programmable gain amplifier (DPGA), and an optical
black (OB) correction loop. Data are output in a 12-bit
word; two-channel ADC data are multiplexed and
then output.
