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 48):
A method for bringing up a communication link between first and second end points including a plurality of cascaded retimers interposed along the communication link and interconnected via a plurality of link segments, each of the first and second end points having a transmitter and receiver, each retimer including a first port having a first transmitter and a first receiver and a second port having a second transmitter and a second receiver, the method comprising:\n concurrently training each of the first and second receivers of each of the plurality of retimers and the receivers of the first and second end points; for each of the retimers,\n 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 a receiver ready signal received at a receiver of one of the first and second ports to be passed through the retimer and be transmitted out of the transmitter of the other port, \n \n otherwise preventing receiver ready signals from passing through the retimer until each of the first and second receivers of the retimer have been trained.
