ASYMMETRIC DUPLEX TRANSMISSION DEVICE AND SWITCHING SYSTEM THEREOF

摘要

The present invention provides an asymmetric duplex transmission device and a switching system employing the same. The master device and the slave device communicate with each other through a single clock and full duplex data channels. It can also switch the duplex data channels between a plurality of slave devices under limited resources.

主权项

1. An asymmetric duplex transmission device, comprising:
a master device, comprising a first phase lock loop and a master transceiver module coupled to the first phase lock loop; and at least one slave device coupled to the master device, each slave device comprising a slave transceiver module; wherein the master transceiver module transmits a forward clock to the slave transceiver module through a first transmission medium, transmits a forward data to the slave transceiver module through a second transmission medium, and receives a backward data transmitted from the slave transceiver module through a third transmission medium; and wherein the first phase lock loop provides a first clock that is used when the master transceiver module transmits the forward clock and the forward data to the at least one slave device and receives the backward data from the at least one slave device.
