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.

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 high speed 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.

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.

PARALLEL I/O

? 10-bit Dual Data Rate (DDR) parallel interface.

? Selectable source simultaneous or source synchronous transmit and receive parallel interfaces.

? Convenient output clock for user friendly ASIC timing.

? Interoperates with SSTL2 and 1.8V LVCMOS standard.

TRUNKING &TIMING

? Integrated Receive FIFO synchronizes incoming data to local clock domain.

? Trunking feature de-skews and aligns all four channels to form a single 10 Gbit/s logical link

TEST FEATURES

? Extensive control of loopback, BIST, and operating modes via 802.3 compliant MDC/MDIO serial interface.

? On-chip packet generator/checker provides at-speed diagnostics.

? Built-in error counters per channel.

? Support for IEEE 1149.1 JTAG testing on all pins.

PHYSICAL

? 1.8V, 0.18 micron standard CMOS technology with 2.5V tolerant I/O.

? 289-ball PBGA (19mm x 19mm package).

APPLICATIONS

? High speed serial backplanes

? 10 GE links

? Fibre Channel transceivers

? Infiniband transceivers

? XAUI retimers

? Intra-system interconnect
