Abstract
A novel system for selectively referencing transmit data transferred from a repeater to a physical layer transmitter via a Media Independent Interface (MII), to an input clock selected depending on a mode of MII operations. A clock select input determines whether transmit data is referenced to a selected input clock or to a MII transmit clock output. An analog phase-locked loop (APLL) is supplied with the selected input clock to produce a signal for driving a wave shaper that converts the MII transmit data into a required format for 10 Mb/s operations.
