.. xr PRELIMINARY REV. P1.0.5 2.488/2.666 GBPS STS-48/STM-16 SONET/SDH TRANSCEIVER APRIL 2005 GENERAL DESCRIPTION The XRT91L82 is a fully integrated SONET/SDH transceiver for OC-48/STM16 applications supporting the use of Forward Error Correction (FEC) capability. The transceiver includes an on-chip Clock Multiplier Unit (CMU), which uses a high frequency PhaseLocked Loop (PLL) to generate the high-speed 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 ining serial data stream. The chip provides serial-to-parallel and...
