Abstract

A multiple data-rate receiver uses a signal rate detection technique that employs comparators to obtain information on the incoming data rate for enabling the appropriate receiver. Once a data rate is determined, only then is the appropriate receiver activated. Hence, power dissipation is kept to a minimum during the autonegotiation phase. This is a significant improvement over existing art which require two (or more) receivers to be active during the autonegotiation phase, consequently demanding high power dissipation. Because the autonegotiation phase can be lengthy, the present technique is preferable in many cases.
