PM8355
QuadPHY-II™
Advance
4-Channel 2.125, 2.5 and 3.125 Gbit/s Transceiver with Half-rate Support
GENERAL DESCRIPTION
SERIAL I/O
TEST FEATURES
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.
• 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.
• 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
PARALLEL I/O
PHYSICAL
• 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.
• 1.8V, 0.18 micron standard CMOS
technology with 2.5V tolerant I/O.
• 289-ball PBGA (19mm x 19mm
package).
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.
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.

EXAMPLE ARCHITECTURE
interface to a working and protect fabric.
The figure below shows a multi-service
switching platform using QuadPHY-II
devices for backplane interconnect and
client signal physical interfaces.
The 10GE line cards use the QuadPHYII as a PHY supporting XAUI on the line
side and mating to a 10GE MAC using
XGMII.
As a serial backplane transceiver, the
redundant high-speed links simplify the
Infiniband and Fibre Channel line cards
applications are also shown. The half-
rate mode of the QuadPHY-II enables 1
and 2 Gbit/s support using the same
device.
The other applications shown are a XAUI
retimer and an XGMII extender where
the MAC and Optics module separated
by longer distance.
