2.488 GBPS FULLY INTEGRATED LOW POWER SONET/SDH TRANSCEIVER
Application Block Diagram
• Fully integrated OC-48/STM-16 SONET/SDH transceiver with
CDR, MUX, DEMUX, and CMU
16-bit, 155.52-Mbps LVPECL interfaceUse Bullet for these
On-chip, PLL-based clock generator
Loss-of-signal (LOSB) output
Line and system loopback modes
Lock detect
Meets SONET, Telcordia, and ITU-T jitter requirements
Power supply: 2.5V (core), 3.3V (LVPECL I/O)
Power dissipation: 1.2W typical
14 ¥ 20 mm,128-pin PQFP package
Standard CMOS fabrication process
First CMOS OC-48 transceiver in the world.
Low power consumption eliminates external heat sink, fans for
system airflow, and expensive high current power supplies.
High integration reduces design cycle and time to market.
Increased port density per board and system.
CMOS-based device takes advantage of the most effective
silicon economy of scale.
Features low-jitter CMU: 3 mUIRMS typical.
Target applications:
OC-48/STM-16 transmission equipment
SONET/SDH optical modules and test equipment
ADD/DROP multiplexers
Digital cross-connects
ATM switch backbones
Terabit routers
Edge routers
