Abstract: Multiple channel synchronized clock generation scheme. A novel approach is presented herein in which synchronized clock signals are generated that can be used in parallel processing of deserialized signals. When a serial input signal is received, it can be deserialized into a plurality of parallel signals, and each of these parallel signals can be processed at a frequency that is lower than the frequency of the serial signal. Overall, the frequency at which all of the parallel signals are processed can be the same or substantially close to the frequency of the serial signal, so that throughput within a communication system is not compromised or undesirably reduced. This novel approach is operable to perform independent adjustment of the operational parameters within an apparatus that is operable to perform multiple channel synchronized clock generation (e.g., phase rotation and/or division of signals within each of the individual channels can be adjusted independently).

Abstract: Fully redundant clock systems are provided on network nodes coupled by redundant multisegment psuedowires (MSPWs) within an internet-protocol (IP)-based mobile backhaul network. The primary clock system includes a primary master clock on a first node and a primary slave clock on a second node coupled via a primary MSPW, while the secondary clock system includes a secondary master clock on the first node and a secondary slave clock on the second node coupled via a secondary MSPW. The primary and secondary slave clocks synchronize with their respective primary and secondary master clocks via their respective MSPWs. A clock controller maintains the secondary clock system in a hot-stand-by mode, and upon determining that a switch-over is needed, automatically switches from the primary clock system to the secondary clock system.
