SNAS636A – DECEMBER 2013 – REVISED OCTOBER 2014

Typical Applications (continued)

9.2.2.3 Termination for AC Coupled Differential Operation

AC coupling allows for shifting the DC bias level (common mode voltage) when driving different receiver

standards. Since AC coupling prevents the driver from providing a DC bias voltage at the receiver, it is important

to ensure the receiver is biased to its ideal DC level.
