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 communi-
cation links. It is applicable for PMA-
PMD 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 pre-
emphasis 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
