摘要：

This letter highlights features of an optimized serial communication system, including an oversampling technique of data recovery, issues related to off-board communications and a modified Universal Asynchronous Receiver Transmitter (UART) implemented in programmable logic device (PLD), The resulting system provides high skew tolerance at 44 Mb/s data rate and has achieved a transmission distance of 130 m, at this rate, with the aid of an enhanced differential transceiver circuit. The principal application is for embedded systems with medium distance communication requirements, This UART can be integrated with other communication functions, such as packet routing switches, in a PLD device.
