20160188506 | TRANSCEIVER MULTIPLEXING OVER USB TYPE-C INTERCONNECTS - An apparatus for transceiver multiplexing over USB Type-C interconnects is described herein. The apparatus includes a processor, a memory, a USB Type-C connector, a first transmitter, a multiplexed transmitter, a multiplexed receiver, and an on-die inductor. The multiplexed transmitter, when disabled, enables the multiplexed receiver to be in communication over a channel with a second transmitter over the USB Type C connector. The multiplexed receiver, when disabled, enables the multiplexed transmitter to be in communication over the channel with a receiver over the USB Type-C connector. The on-die inductor is disposed in serial with the multiplexed transmitter, and disposed in parallel with the multiplexed receiver. The on-die inductor reduces: effective shunt capacitance and insertion loss between the multiplexed transmitter and the channel; effective shunt capacitance and insertion loss between the channel and the multiplexed receiver. | 06-30-2016 |
