BL8531H
AFE FOR CCD/CIS SIGNAL PROCESSOR
GENERAL DESCRIPTION
The samsung analog front end(AFE) for CCD/CIS image signal is an integrated analog signal processor for color
image signal.
The AFE converts CCD/CIS output signal to digital data. The AFE includes three-channel CDS(Correlated
Double Sampling) circuit, PGA(Programmable Gain Amplifier), and 12-bit analog to digital converter with
reference generator.
A parallel data bus provides a simple interface to 8-bit microcontroller.
