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 35):
A retimer device, comprising:\n a first port having a first transmitter and a first receiver coupled to a first plurality of buffers; a second port having a second transmitter and a second receiver coupled to a second plurality of buffers; first and second retimer circuitry coupled between the first plurality of buffers and the second plurality of buffers; and circuitry and logic that is configured, when that retimer device is implemented in a communication link between first and second end points including a first link segment coupling the first end point to the retimer and a second link segment coupled between the retimer and the second end point, to,\n transmit signals to and receive signals transmitted from the first end point in connection with performing first link training operations over the first link segment, the first link training operations use to train the first receiver of the retimer device and a receiver of the first end point; \n transmit signals to and receive signals transmitted from the second end point in connection with performing second link training operations over the second link segment, the second link training operations use to train the second receiver of the retimer device and a receiver of the second end point; \n determine that each of the first and second receivers of the retimer device have been trained, and in response thereto,\n configuring the retimer device 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.
