Abstract
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.
Claims23
A repeater device configured to repeat source synchronous data, said device comprising:
- a first interface configured to receive source synchronous data comprising a first data and corresponding first clock signal;
- a second interface configured to transmit source synchronous data;
- and
- a circuit coupled to said first interface, wherein said circuit is configured to:
- utilize said first clock signal in order to recover said first data;
- and
- transmit said recovered first data and a corresponding clock via said second interface in a source synchronous manner.
A method for repeating source synchronous data, said method comprising:
- receiving source synchronous data;
- receiving a source synchronous clock signal corresponding to said data;
- utilizing said clock signal to recover said data;
- and
- transmitting said recovered data and a corresponding clock in a source synchronous manner.
A source synchronous system comprising:
- a source device configured to convey source synchronous data comprising a first data and corresponding first clock signal;
- a repeater device coupled to said source device, wherein said repeater device comprises:
- a first interface configured to receive said source synchronous data;
- a second interface configured to transmit source synchronous data corresponding to said received source synchronous data;
- and
- a control circuit configured to:
- utilize said first clock signal in order to recover said first data;
- and
- transmit said recovered first data and a corresponding clock via said second interface in a source synchronous manner;
- a destination device coupled to said repeater device, wherein said destination device is configured to receive source synchronous data from said repeater device.
