The device uses bi-phase-level encoding to embed a clock signal into a data stream for transmission across a communications link. In this encoding mode, a logic one is represented by a high-to-low transition in the center of the bit cell, while a logic zero is represented by a low-to-high transition. The Manchester encoder combines the clock (CIN) and data (DIN) into a single bi-phase-level signal (TX). An inverted version of this signal (TXB) is also available. The data baud rate (in MBaud) is equal to the input clock frequency (in MHz). A replica of the clock input is also available (CBUF). The encoder may be reset by setting the RESB input low; otherwise, it should be left high. The TX and TXB signa...
