BCM8220
®
2.488/2.667 GBPS ULTRA LOW POWER SONET/SDH TRANSCEIVER
FEATURES
•
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
SUMMARY OF BENEFITS
•
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.
•
Both line and system loopback modes
•
Additional diagnostic features include lock detect and loss of
signal.
•
Meets SONET/SDH jitter requirements
