This paper presents a transmitter FIR filter and a coefficient adaptation method based on exploration of the receive eye at the far end receiver. This method does not require backchannel or coding overhead and does not involve any proprietary functionality in the far-end SerDes. The transmitter FIR and the proposed adaptation method were proven in a CMOS 65 n SerDes over a variety of copper media for data-rates up to 9.4 Gbps.
