2.488/2.667 GBPS ULTRA LOW POWER SONET/SDH TRANSCEIVER
FEATURES
SUMMARY OF BENEFITS
• OC-48/STM-16 SONET/SDH transceiver
• Selectable full-duplex transmission between standard rate of
2.488 Gbps or Forward Error Correction rate of 2.667 Gbps.
• Single-chip, integrated solution containing multiplexer (Mux),
clock multiplication unit (CMU), demultiplexer (Demux), and
clock data recovery (CDR) functions.
• 4-bit, 622.08/666.84-MHz, LVDS system interface
• Both line and system loopback modes
• Additional diagnostic features include lock detect and loss of
signal.
• Meets SONET/SDH jitter requirements
• Low power dissipation of 550 mW typical
• Operates at 1.8V
• 1.8V or 3.3V CMOS I/O interface
• Standard CMOS fabrication process
• Two packages offered:
• 100-pin QFP package, 14 mm ∞ 14 mm ∞ 1.4 mm
• 100-pin BGA package, 11 mm ∞ 11 mm ∞ 1.71 mm
• Ultra low power consumption eliminates external heat sinks,
fans for system airflow, and expensive high current power
supplies.
• High integration reduces design cycle and time to market.
• Features increased port density per board and system.
• Selectable standard OC-48/STM-16 rate of 2.488 Gbps or
Forward Error Correction rate of 2.667 Gbps, allowing for
easy system configuration to maximize transmission
bandwidth and data availability.
• Extensive diagnostic features provide easy system
troubleshooting.
• Compliant with industry standards to reduce design cycle and
time to market.
• CMOS-based device takes advantage of the most effective
silicon economy of scale.
APPLICATIONS
• OC-48/STM-16 transmission Equipment
• SONET/SDH optical modules
