    Abstract: A system for data transmission includes a physical (PHY) layer which has a rate detection module which determines an adopted clock rate. The rate detection module provides a rate detection signal indicative of the adopted clock rate. The PHY layer includes a reference clock generator which has an input coupled to receive the rate detection signal and an output to provide a reference clock output. The PHY layer includes a PHY interface which has a first input coupled to receive the reference clock output, a data input and a data output. The PHY interface receives data from a MAC interface at the data input and transmits data to the MAC interface through the data output responsive to the reference clock output.

    Abstract: Systems, apparatus, articles of manufacture, and methods are described for precise timestamping of an Ethernet frame. In some implementations, a device may include network interface circuitry; logic circuitry configured to execute instructions to cause the logic circuitry to: determine a first delay introduced by a physical coding sublayer circuitry at a first time; adjust a first timestamp associated with a first transmission based on the first delay, the first timestamp transmitted with the first transmission; determine a second delay introduced by the physical coding sublayer circuitry at a second time, the second delay different than the first delay; and adjust a second timestamp associated with a second transmission based on the second delay, the second timestamp transmitted with the second transmission.
