A 5.2Gbps hypertransportTM integrated AC coupled receiver with DFR DC restore

A HyperTransport
^TM
receiver with integrated AC coupling achieves an extended DC input common mode voltage without resorting to AC encoding like 8B10B. The receiver supports all HyperTransport
^TM
Revision 3 (HT3) data rate from 2.4 Gbps to 5.2 Gbps. A decision feedback restore (DFR) method is used to counter baseline wander. The design is implemented in a 65 nm SOI CMOS process.
