ABSTRACT:
A communications circuit comprises a first filter having a first corner frequency that is programmable. A data type identifier tracks first and second types of data flowing through the communications circuit. A control module communicates with the first filter and the data type identifier and adjusts the corner frequency of the first filter based on the first and second types of data.
