An apparatus comprising a transmission line, a receiver circuit, and a high pass filter circuit coupled between the transmission line and a receiver circuit input. The receiver circuit is configured to receive a data signal over the transmission line at a first data rate. The high pass filter circuit is connected between the transmission line and a receiver circuit input and has a corner frequency that is less than approximately the first data rate and is greater or equal to than approximately one-half the second data rate. The second data rate is an effective data rate caused by an expected data pattern on the transmission line. Other devices, systems, and methods are disclosed.
