摘要: A transceiver system is described. A secondary memory module is coupled to a primary channel for receiving data and signals from a controller. The secondary memory module comprises a memory and a secondary channel for transmitting the data and control signals to the memory. The secondary memory module further comprises a transceiver coupled to the primary channel and the secondary channel. The transceiver is designed to electrically isolate the secondary channel from the primary channel. The transceiver is a low latency repeater to permit the data and the control signals from the controller to reach the memory, such that a latency of a data request from the controller is independent of a distance of the transceiver from the controller.

摘要: In a transceiver system a first interface receives data from a first channel using a first clock signal and transmits data to the first channel using a second clock signal. A second interface receives data from a second channel using a third clock signal and transmits data to the second channel using a fourth clock signal. A re-timer re-times data received from the first channel using the first clock signal and retransmits the data to the second channel using the fourth clock signal.
