2.488/2.667 GBPS ULTRA LOW POWER SONET/SDH TRANSCEIVER
BCM8220 Application Block Diagram
• 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.
