CS is a dual function pin, which determines the state of SDO, as well as the digital logic-low output
level. When CS is low, SDO will be active. When high, the SDO pin will output a high-impedance state.
The logic-low level of SDO will match the active-low voltage on CS.
SDO is the serial data output. It will output a high-impedance state if CS = 1. The logic-low level of SDO
will match the active-low voltage on CS.
SCLK is the serial bit-clock which controls the shifting of data from the ADCs. This input goes through a
Schmitt trigger to allow for slow rise and fall time signals. If held high, the device will enter sleep mode.
In the CS5510/12, this input is also used as a master clock source which determines conversion speeds
and throughput. In the CS5511/13, SCLK is only used to read the conversion data and put the part in
sleep mode.
