A NOVEL PHYSICAL-LAYER TRANSCEIVER USED IN USB2.0 SERIAL DATA LINK

The paper proposes a novel transceiver in physical layer for high-speed serial data link based upon Universal Serial Bus （USB） 2.0, comprising transmitter and receiver. In the design, transmitter contains pre-and-main driver to satisfy slew rate of output data, receiver includes optimized topology to improve precision of received data. The circuit simulation is based on Cadence＇s spectre software and Taiwan Semiconductor Manufacture Corporation＇s library of 0.25μm mixed-signal Complementary Metal-Oxide Semiconductor （CMOS） model. The front and post-simulation results reveal that the transceiver designed can transmit and receive high-speed data in 480Mbps, which is in agreement with USB2.0 specification. The chip of physical-layer transceiver has been designed and implemented with 0.25μm standard CMOS technology.
