Ground 2. This is the ground reference point for all circuitry on the nonisolated side.
11 MDAT Serial Data Output. The single bit modulator output is supplied to this pin as a serial data stream. The bits are
clocked out on the rising edge of the MCLKIN input and valid on the following MCLKIN rising edge.
13 MCLKIN Master Clock Logic Input. 20 MHz maximum. The bit stream from the modulator is valid on the rising edge of MCLKIN.
14 V
DD2
Supply Voltage. 3 V to 5.5 V. This is the supply voltage for the nonisolated side and is relative to GND
