Abstract
A physical layer device (PLD), comprising: a first serializer-deserializer (SERDES) device having a first parallel port; a second SERDES device having a second parallel port; a third SERDES device having a third parallel port; and a path selector being selectively configurable to provide either (i) a first signal path between the first and second parallel ports, or (ii) a second signal path between the first and third parallel ports.
Claims18
A physical layer device (PLD), comprising:
- a first serializer-deserializer (SERDES) device;
- a second SERDES device;
- and
- a path selector, coupled between the first SERDES device and the second SERDES device, configured:
- (i) to pass a first deserialized data signal and a first clock signal from the first SERDES device to the second SERDES device, and
- (ii) to pass a second deserialized data signal and a second clock signal from the second SERDES device to the first SERDES device,
- wherein the first clock signal and the second clock signal are synchronized with the first deserialized data signal and the second deserialized data signal, respectively.
4 more elements
A path selector for a physical layer device (PLD), comprising:
- a first bi-directional signal path configured and arranged to pass a first deserialized data signal and a first clock signal from a first serializer-deserializer (SERDES) device to a second SERDES device, wherein the first clock signal is synchronized with the first deserialized data signal;
- and
- a second bi-directional signal path configured and arranged to pass the first deserialized data signal and the first clock signal from the first SERDES device to a third SERDES device,
- wherein the path selector is configured to select from among the first bi-directional signal path and the second bi-directional signal path in response to a control signal.
1 more element
A method for data communication, comprising:
- (a) deserializing, by a first serializer-deserializer (SERDES) device, a first serial data signal to produce a first deserialized data signal;
- (b) recovering, by the first SERDES device, a first clock signal from the first serial data signal;
- (c) selecting a signal path from among a plurality of signal paths in a path selector to pass the first deserialized data signal and the first clock signal from the first SERDES device to the second SERDES device;
- (d) receiving, by a second SERDES device, the first deserialized data signal and the first clock signal;
- and
- (e) serializing, by the second SERDES device, the first deserialized data signal in accordance with the first clock signal to produce a second serial data signal.
