ESCRIPTION
The VSC8113 is an ATM/SONET/SDH-compatible transceiver integrating an on-chip Clock Multiplication Unit
(CMU) for the high-speed clock as well as a Clock and Data Recovery (CDR) unit with 8-bit serial-to-parallel and
parallel-to-serial data conversion. The Phase-Locked Loop (PLL) clock is used for serialization in the transmit
direction (Mux). The recovered clock is used for deserialization in the receive direction (Demux). The demultiplexer
contains SONET/SDH frame detection and recovery. The device provides both facility and equipment loopback
modes and two loop timing modes. The VSC8113 is packaged in a 100-pin PQFP with integrated heat spreader for
optimum thermal performance and reduced cost. The VSC8113 provides an integrated solution for ATM physical
layers and SONET/SDH systems applications.
