Integrated Cross Point Switches activate the input selected by the user. In single channel mode, one of the four inputs can be selected as valid input to the single ADC channel. In dual channel mode, any two of the four inputs can be selected to each ADC channel. In quad channel mode, any input can be assigned to any ADC channel. An internal, low jitter and programmable clock divider makes it possible to use a single clock source for all operational modes. The ASD5020 is based on a proprietary structure, and employs internal reference circuitry, a serial control interface and a serial LVDS output data. Data and frame synchronization clocks are supplied for data capture at the receiver. Internal digital fine gain can be set separately for each ADC to calibrate for gain errors. Various modes and configuration settings can be...
