Abstract
A network node includes a serial physical sublayer (PHY) chip, a parallel PHY chip, and a media access control (MAC) chip. The serial physical sublayer chip, includes a single bit transmit data input, a single bit receive data output, and serial PHY control signal input/output (I/O) lines. The parallel PHY chip includes a multi-bit transmit data input, a multi-bit receive data output, and parallel PHY control signal I/O lines. The MAC chip includes a multi-bit transmit data output, a multi-bit receive data input and parallel control signal I/O lines. The multi-bit transmit data output is connected to the multi-bit transmit data input. One bit of the multi-bit transmit data output is connected to the single bit transmit data input. The multi-bit receive data input is connected to the multi-bit receive data output. One bit of the multi-bit receive data input is connected to the single bit receive data output. The parallel control signal I/O lines are connected to the parallel PHY control signal I/O lines. A subset of the parallel control signal I/O lines are connected to the serial PHY control signal I/O lines.
