BCM8220

2.488/2.667-Gb/s SONET/SDH Transceiver

Currently Viewing:

The world's lowest-power, highest-integrated and smallest OC-48 SONET transceiver chip. The BCM8220 requires only one-fourth the power dissipation of competitive solutions. It is also the world's first OC-48 transceiver to feature a pin-efficient, four-bit, 622.08 Mb/s LVDS interface, which is the preferred interface standard for next-generation SONET equipment.
 
The BCM8220 FEC-capable (forward error correction), SONET/SDH transceiver is a fully integrated, SONET OC-48 (2.488/2.667 Gb/s) interface serialization/deserialization device with an integrated clock multiplication unit (CMU) and integrated clock and data recovery (CDR) circuit. Output frequency is selectable at 2.488 Gb/s or 2.667 Gb/s, allowing the user to use the FEC capability. On-chip clock synthesis is performed by the high-frequency, low-jitter, phase-locked loop on the BCM8220 transceiver chip, allowing the use of slower 77.76/155.52 MHz (83.35/166.71 MHz) external transmit clock references.
