Overview

The WM8199SCDS/RV is a 16-bit analog front end/digitizer IC that processes and digitizes the analog output signals from CCD sensors or Contact Image Sensors (CIS) at pixel sample rates of up to 20MSPS. The device includes three analog signal processing channels each of which contains reset level clamping, Correlated double sampling and programmable gain and offset adjust functions. Three multiplexers allow single channel processing. The output from each of these channels is time multiplexed into a single high-speed 16-bit analog-to-digital converter. The digital output data is available in eight or four-bit wide multiplexed format. An internal four-bit DAC is supplied for internal reference level generation. This may be used during CDS to reference CIS signals or during Reset Level Clamping to clamp CCD signals. An internal 4-bit DAC is supplied for internal reference level generation. This may be used during CDS to reference CIS signals or during Reset Level Clamping to clamp CCD signals. An external reference level may also be supplied. ADC references are generated internally, ensuring optimum performance from the device. Using an analog supply voltage of 5V and a digital interface supply of either 5V or 3.3V, the WM8199SCDS/RV typically only consumes 330mW when operating from a single 5V supply.
