Preliminary
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.

APPLICATION CONSIDERATIONS
The digital outputs load should be minimized, either by using short traces to the digital ASIC, or by using
external digital buffers. In order to minimize the number of code conversion in the main output of the impact of
transients, which should happen in the coincidences CDSCLK2 falling on or before ADCCLK rising edge. All 0.1μF
decoupling capacitor should be located as close as possible to the M1008 pins. When operating in a single channel
mode, the unused analog inputs should be grounded.
For the 3-channel SHA mode, all of the above considerations also apply for this configuration, except that the
analog input signals are directly connected to the M1008 without the use of coupling capacitors. The OFFSET pin
should be grounded if the inputs to the M1008 are to be referenced to ground, or a DC offset voltage should be
applied to the OFFSET pin in the case where a coarse offset needs to be removed from the inputs. The analog input
signals must already be dc-biased between 0V and 2V, if OFFSET is connected to ground.
