Overview

The WM8214SCDS/RV is a 16-bit analog front end/digitizer IC which processes and digitizes the analog output signals from CCD sensors or Contact Image Sensors (CIS) at pixel sample rates of up to 40MSPS. 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 8-bit wide multiplexed format and there is also an optional single byte output mode, or 4-bit multiplexed LEGACY mode. 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 3.3V and a digital interface supply of 3.3V, the WM8214SCDS/RV typically only consumes 390mW.
