Abstract:
Methods and apparatus for implementing adaptive equalization channel extension retimer link-up in high-speed serial links. Under aspects of the proposed methodology, the retimer device intervenes with the adaptive equalization training, training both ends of the link individually between the two end points, and once both of the retimer's receivers are trained, it propagates the receiver readiness indication through from one end point to the other. This allows all sections of the link to train at the same time, and for all devices to transition to data mode at the same time, once all channels have been adapted to and trained. This methodology also applies to cascaded retimer device configurations, where multiple retimers are being used to extend the channel even further.

Claim (Index 43):
A system comprising:\n first and second end points, each end point including,\n a transmitter; and \n a receiver; \n a retimer, including,\n a first port having a first transmitter and a first receiver coupled to a first plurality of buffers; \n a second port having a second transmitter and a second receiver coupled to a second plurality of buffers; and \n first and second retimer circuitry coupled between the first plurality of buffers and the second plurality of buffers; \n a first link segment, respectively coupling the transmitter and receiver of the first end point device to the first receiver and first transmitter of the retimer; a second link segment, respectively coupling the transmitter and receiver of the second end point device to the second receiver and second transmitter of the retimer; wherein the first and second end points are linked in communication over a communication link comprising the first and second link segments and the retimer, and wherein the first and second end points and the retimer are configured to perform operations to bring up the communication link including, concurrently training each of the first and second receivers of the retimer and the receivers of the first and second end points; determining that each of the first and second receivers of the retimer have been trained, and in response thereto,\n configuring the retimer to pass through receiver ready signals to enable receiver ready signals transmitted by the first and second end points to be received by the receiver of the other end point; and \n once receiver ready signals have been received by each of the receivers on the first and second end points, transitioning to a data mode to enable data to be transmitted over the communication link, wherein the data signals are passed through the retimer.
