PM8355

Advance PM8355 QuadPHY-II™ 4-Channel 2.125, 2.5 and 3.125 Gbit/s Transceiver with Half-rate Support GENERAL DESCRIPTION The QuadPHY-II is a physical layer transceiver ideal for systems requiring high speed point-to-point communication links. It is applicable for PMAPMD connections in 10 GE, Infiniband 1 or 4 x 2.5 Gbit/s links, 1 and 2 Gbit/s Fibre Channel, as well as high speed serial backplanes for high capacity systems. SERIAL I/O Redundant high speed serial I/O channels for convenient switching to redundant fabric. High speed outputs with optional preemphasis to drive longer backplanes. High speed I/O with on-chip termination resistors to directly drive dual-terminated 50 Ohm lines. TEST FEATURES Extensive control of loopback, BIST, and operating modes via 802.3 compliant MDC/MDIO serial interface. On-chip packet generator/checkerprovides at-speed diagnostics. Built-in error counters per channel. Support for IEEE 1149.1 JTAG testing on all pins. FEATURES GENERAL 10Gbit/s, bi-directional, XAUI to XGMII link supporting the proposed IEEE 802.3ae (the standard is draft and is subject to change). Four independent 2.125, 2.5 and 3.125 Gbit/s Serdes for Fibre Channel, Infiniband, 10 GE line cards and highspeed backplane applications. Half/Full rate mode selectable per channel. Integrated serializer/ deserializer, clock synthesis, clock recovery and 8B/10B encode/decode logic. Under 2 Watts typical power. PARALLEL I/O 10-bit Dual Data Rate (DDR) pa...
