... There are two clock inputs, CLKI and BYCLK, going into the VSC8021. These two clocks serve as timing references for different parts of the VSC8021. The BYCLK is used to trigger the input registers for the parallel data inputs, while the CLKI is used to trigger the high-speed serial output register as well as some of the timing circuitry for the parallel to serial conversion ...

... CLKI. The phase of RCLK, RCLKN is not affected by the self- adjusting circuitry, therefore it can be used as a system reference clock. RCLK, RCLKN can be used by the sys- tem designer to generate BYCLK, BYCLKN. The self-positioning timer and RCLK, RCLKN allow for the cre- ation of very tight parallel data timing for the VSC8021.

... Data Sheet VSC8021/VSC8022 VSC8022 The VSC8022 contains both a 1:8 demultiplexer and SONET frame recovery circuitry. The 1:8 demultiplexer accepts a serial data input ( DI, DIN ) at rates up to 2.5Gb/s and converts it into 8 parallel differential ECL data outputs ( D1-D8, D1N-D8N ) at rates up to 312.5Mb/s. Valid parallel data outputs are indicated by the divide by 8 differential clock outputs BYCKO, BYCKON ...
