Description: 2.488/2.666GBPS OC-48/STM-16 SONET/SDH TRANSCEIVER

Features

* 2.488 / 2.666 Gbps Transceiver
* Single-chip fully integrated solution containing parallel-to-serial converter, clock multiplier unit (CMU), serial-to-parallel converter, limiting amplifier and clock data recovery (CDR) functions
* 4-bit LVDS data paths at 622/666 MHz com

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 C
