A 5.2Gbps HyperTransport^TM Integrated AC
Coupled Receiver with DFR DC Restore

 

Abstract

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 HyperTransportTM Revision 3 (HT3) data rate from 2.4 Gbps to 5.2Gbps. A decision feedback restore (DFR) method is used to counter baseline wander. The design is implemented in a 65nm SOI CMOS process.
