4-Port Gigabit Ethernet and 1/2G Fibre Channel Repeater or Retimer

GENERAL

• Supports four physical interfaces for
Gigabit Ethe rnet at 1.25 Gbit/s per
IEEE 802.3z or Fibre Chan nel phys ical
interfaces at 1.0 625 or 2.125 Gbit/s per
Fibre Channel Physical Interface (FC­PI) for repeating or retiming
applications.

• Backplane repeating/retiming signal
integrity features enable standards
compliance, link extension and robust
gigabit-serial operation in the hostile
backplane environment.

• Provides direct connection to high­speed serial backplanes, coax
stacking cables, or optical / copper
Small Form Factor Pluggable (SFP)
modules.

• Provides non-blocking cross-bar for
protection switching and data bi-cast,
multi-cast or broadcast.

• Fast high-speed serial lock times and
low device latency.

• Rate detection/auto-s elec tion betwe en
1G and 2G Fibre Channel.

• Extensive per port backplane
monitoring for loss of sign al, error rate s,
and link level violations.

• Supports single-ended or differential
125 MHz reference clock for Gigabit
Ethernet, or 106.25 MHz reference
clock for Fibre Channel applications.

HIGH-SPEED INTERFACE

• High-speed outputs wi th sel ec tab le
output amplitude and programmable
pre-emphasis per port to counteract
dielectric losses and allow maximum
reach on printed circuit boards and
cables.

• Programmable receive input
equalization provides robust data
recovery of highly degraded input
signals.

• Minimal board footprint and exceptional
signal integrity achieved:

• No external compone nts are require d

to interface the high-speed signal s
due to internal AC coupling.

• Programmable receive input

termination of 100 ohm or 150 ohm
differential.

• Programmable output impedance of

100 ohm or 150 ohm differential.

TEST AND CONTROL

• Digital loss of link (DLOL) detect pin
provides status output for monitoring
individual or multiple links.

• DLOL and optional interrupt pin can be
programmed to indicate:

• Analog loss of signal.

• Excessive 8B/10B code and disp arity

violations.

• Fibre Channel comma density.

• Loss of synchronization to detect
Gigabit Ethernet or Fibre Channel
framing errors.

• Internal packet generator and
comparator features simplify backplane
and jitter testing via:

• Programmable pattern (can be used

with GE high, low and mixed
frequency tests).
