US Patent 7139308 Source synchronous bus repeater

A device configured to recover and repeat source synchronous data. In one embodiment, the device is configured to receive source synchronous data via a first interface, recover the received data utilizing a corresponding received source synchronous clock signal, and transmit the recovered data and a corresponding clock signal in a source synchronous manner. In one embodiment, the device is configured to operate as a repeater without benefit of an internal clock signal. In addition, the device may be configured to remove data jitter and renew or restore amplitude to attenuated signals prior to retransmission.
