PRODUCTION DATA
The ADC364x provides a SDR output clocking option for all serial CMOS output modes (including decimation) which is enabled using the SPI interface. In serial CMOS mode by default the data is output on rising and falling edge of DCLK. In SDR clocking mode, DCLKIN has to be twice as fast as the default DCLKIN so that the output data are clocked out only on DCLK rising edge.
Internally DCLKIN is divided by 2 for data processing and this operation can add 1 extra clock cycle latency to the ADC latency.
