FEATURES
2.488 / 2.666 Gbps Transceiver
Targeted for SONET OC-48/SDH STM-16 Applications
Selectable full duplex operation between standard rate of 2.488 Gbps or Forward Error Correction rate of
2.666 Gbps
Single-chip fully integrated solution containing parallel-to-serial converter, clock multiplier unit (CMU), serial-
to-parallel converter, and clock data recovery (CDR) functions
16-bit Differential LVDS/LVPECL, or Single-Ended LVPECL signaling data paths running at 155.52/166.63
Mbps using internal input termination for reduced passive components on board
Non-FEC and FEC rate REF1CLKP/N and REF2CLKP/N dual reference input ports
Supports 155.52/166.63MHz or 77.76/83.31MHz transmit and receive external reference input ports
Optional VCXO input port support multiple de-jittering modes in Host mode
On-chip phase detector and charge pump for external VCXO based de-jittering PLL
Internal FIFO decouples transmit parallel clock input and transmit parallel clock output
Provides Local, Remote Serial and Remote Parallel Loopback modes as well as Loop Timing mode
Diagnostics features include various lock detect functions and transmit CMU and receive CDR Lock Detect
