Abstract: At least some aspects of the present disclosure provide for a method. In some examples, the method includes receiving, at a circuit, data via a differential input signal, detecting a rising edge in the data received via the differential input signal, and precharging a common mode voltage (Vcm) node of the differential input signal responsive to detecting the rising edge in the data received via the differential input signal, wherein the Vcm node is a floating node.

Abstract: Aspects of the disclosure provide for a circuit including a squelch detector having a first input coupled to a first node and configured to receive a positive component of a differential signal with a floating center tap, a second input coupled to a second node and configured to receive a negative component of the differential signal, and an output coupled to a logic circuit, a first resistor coupled between the first node and a third node, a second resistor coupled between the third node and the second node, a third resistor coupled between the first node and a fourth node, a fourth resistor coupled between the fourth node and the second node, a capacitor coupled between the fourth node and a ground terminal, a comparator having a first input coupled to the third node, a second input coupled to a fifth node, and an output coupled to the logic circuit.
