Abstract

Output clock adjustment for a digital I/O between physical layer devices and media access controller. A method is disclosed for transferring data received on the input of a physical layer device from a transmission medium to an output associated with the physical layer device and to a media independent layer, the transferred data associated with transferred timing information from the physical layer device to the media independent layer. A receive clock is generated and then the data transitions in the received data are synchronized to at least one edge of the receive clock to provide synchronized receive data. The synchronized received data is then transmitted to the media independent layer. The generated receive clock is delayed by a predetermined clock delay to provide a delayed receive clock, and wherein the data transitions in the synchronized receive data is positioned relative to the rising edge of the delayed receive clock at a predetermined position therein following the rising edge thereof. The delayed receive clock transmitting with the transmitted synchronized receive data.
