WM8181 - 12-bit 2MSPS Serial Output CIS/CCD Digitiser

General Description

The WM8181 is a 12-bit resolution, 2MSPS single channel image digitiser which is designed for easy interface to either CIS or CCD linear image sensors.

Data is output in serial mode.

The applied clock frequency (MCLK) equals the bit rate of the data output.

Key Features

WM8181 12-bit 2MSPS Serial Output CIS/CCD Digitiser Advanced Information, January 2000, Rev 3.0 DESCRIPTION The WM8181 is a 12-bit resolution, 2MSPS single channel image digitiser which is designed for easy interface to either CIS or CCD linear image sensors. Data is output in serial mode. The applied clock frequency (MCLK) equals the bit rate of the data output. The sample rate of the WM8181 can be either 1/12th or 1/16th of the applied master clock frequency. The device can be configured for either single-ended or differential input operation. In single ended input mode, a reset clamp voltage can be applied to the analogue signal, under the control of a digital signal at the CLAMP pin.
