16-BIT CCD/CIS ANALOG SIGNAL PROCESSOR
DESCRIPTION
The M1008 is a 16-bit CCD/CIS analog signal processor for
imaging applications. A 3-channel architecture is designed to sample
and control the outputs of tri-linear color CCD arrays. Each channel
processes one color analog signal and includes an input clamp,
Correlated Double Sampler (CDS), offset DAC and Programmable
Gain Amplifier (PGA), and a 16-bit A/D converter.
If there are sensors such as Contact Image Sensors (CIS) and
CMOS active pixel sensors, the CDS amplifiers are not necessary.
The 16-bit digital output is composed of high and low 8-bit
output and is assessed by two reading cycles. The internal registers
are programmed by a 3-wire serial interface which provides gain,
offset and operating mode adjustments.
The typical operation power of M1008 is 400mW in 5V power supply.
