General Description
The VSC8113 is an ATM/SONET/SDH compatible transceiver integrating an on-chip Clock Multiplication Unit (PLL) for the high speed clock as well as a clock and data recovery unit (CRU) with 8 bit serial-to-parallel and parallel-to-serial data conversion. The PLL clock is used for serialization in the transmit direction (Mux).
