Patent ID: 8166334

Claim:
A redriver having two reference clocks, the redriver coupling an external component through a PCI Express link to a hub, the redriver, comprising: an inbound elastic buffer, comprising: a separate reference clock for an inbound elastic buffer interface between the redriver and the external component, a common reference clock for an inbound elastic buffer interface between the hub and the redriver, and an inbound decoder/descrambler, an inbound scrambler/encoder, and inbound linear shift registers; an outbound elastic buffer, comprising: the separate reference clock for an outbound elastic buffer interface between the redriver and the external component, the common reference clock for an outbound elastic buffer interface between the hub and the redriver, and an outbound decoder/descrambler, an outbound scrambler/encoder, and outbound linear shift registers; and clock recovery logic coupled an external component side of the redriver and to a hub side of the redriver.
