Abstract:
A high-speed bit stream interface module interfaces a high-speed communication media to a communication Application Specific Integrated Circuit (ASIC) via a Printed Circuit Board (PCB). The high-speed bit stream interface includes a line side interface, a board side interface, and a signal conditioning circuit. The signal conditioning circuit services each of an RX path and a TX path and includes a clock and data recovery circuit and an output pre-emphasis circuit. The output pre-emphasis circuit controllably modifies the spectrum of the high-speed bit stream to pre-compensate for the spectral characteristics of a signal path upon which the high-speed bit stream will be output. In the RX path, pre-compensation is performed based upon the properties of the PCB and a servicing connector. In the TX path, pre-compensation is performed based upon the properties of a line side connector and a line side media.
