SCLK is the serial clock input that shifts register data into and out of the ADC. Output data update on the SCLK rising edge and input data are latched on the SCLK falling edge. SCLK is a Schmitt-triggered input designed to increase noise immunity. Even though SCLK is noise resistant, keep SCLK as noise-free as possible to avoid unintentional SCLK transitions. Avoid ringing and overshoot on the SCLK input. A series termination resistor placed at the SCLK driver often reduces ringing.
