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 49):
The method of  claim 48 , wherein the plurality of cascaded retimers are cascaded in a sequence beginning with a first retimer and ending with a last retimer, further comprising:\n in response to the receiver on the first end point being ready, transmitting a receiver ready signal from the transmitter of the first end point over a first link segment coupling the first end point in communication with the first retimer; in response to the receiver on the second end point being ready, transmitting a receiver ready signal from the transmitter of the second end point over a last link segment coupling the second end point in communication with the last retimer, once both the first and second receivers on each of the plurality of cascaded retimers have been trained, passing receiver ready signals through each of the retimers such that receiver ready signals transmitted from the transmitter of the first end point are received by the receiver of the second end point, and receiver ready signals transmitted from the transmitter of the second end point are received at the receiver of the first end point; and transitioning the communication link to a data mode to enable data signals to be transmitted over the communication link between the first end point and the second end point, wherein the data signals are passed through each of the plurality of cascaded retimers.
