Type-C retimer state machine and a protocol for inband control and configuration

摘要

An apparatus for retimer configuration and control is described herein. The apparatus includes at least one retimer. The is to receive an inband low frequency periodic signal (LFPS), and to send an inband LFPS based pulse width modulation message (LBPM) in response to the inband LFPS. The retimer is configured by decoding the LBPM.

主权项

1. An apparatus, comprising:
a port, wherein the port is to transmit a configuration message, wherein the configuration message is an inband LFPS based pulse width modulation message (LBPM); at least one repeater that supports multiple protocols, wherein the repeater is to wait in a low power state, and in response to receiving the configuration message, the repeater is to decode the configuration message to be configured in an operational state.
