10 Reception Path

The PL460 modem has a single-ended reception stage as it is shown in the figure below. It supports a maximum input of 24V_pp without saturation. The signal is adapted to the requirements of the Rx path by means of an Automatic Gain Control (AGC) and a Programmable Gain Amplifier (PGA) as it is described in 10.1.1 PLC Signal Adaptation. Additionally, the reception stage is also capable to detect zero-crosses (in case of being connected to an AC line) if an adapted signal is provided, as it is explained in 10.1.2 Zero-Crossing Detection.
