Part Number: ADC122S051

Hi team,

What is the initial level state of SCLK of ADC122s051 (i.e. the idle state of SCLK)?

Best Regards,
Amy

    Hello Amy,

    The idle state of sclk, this is when CS is high, does not matter for the device.

    The first falling edge, after CS falling edge, is what begins the clocking. This is important for configuring the signal and should be taken into consideration. 

    Regards
