Description
PMC-Sierra,Inc.PM8351 OctalPHY™ 8-Channel 1.0-1.25 Gbps Transceiver .
The OctalPHYTM is an octal PHYsical layer transceiver ideal for systems requiring large numbers of point-to-point gigabit links.
Features
* Eight independent 1.0-1.25 Gbit/s transceivers
* Ultra low power operation: 1.25 Watts typical
* Integrated serializer/deserializer, clock synthesis, clock recovery, and 8B/10B encode/decode logic
* Physical Coding Sublayer (PCS) logic for Gigabit Ethernet
Applications
* High speed serial backplanes Gigabit Ethernet links FibreChannel links Intra-system interconnect ASIC to PMD link
