General Description

The XRT91L81 is a fully integrated SONET/SDH transceiver block for applications in SONET OC-48 allowing the use of Forward Error Correction (FEC) capability.

The transceiver includes an on-chip Clock Multiplier Unit (CMU), which uses a high frequency Phase-Locked Loop (PLL) to generate the highspeed transmit serial clock from slower external clock references.

It also provides Clock and Data Recovery (CDR) functions by synchronizing its on-chip Voltage Controlled Oscillator (VCO) to the incoming serial data stream.
