Dual-Rate Fibre Channel Repeaters
General Description
The MAX3772–MAX3775 are dual-rate (1.0625Gbps
and 2.125Gbps) fibre channel repeaters. They are opti-
mized for use in fibre channel arbitrated loop applica-
tions and operate from a +3.3V supply. The
MAX3772–MAX3775 exceed fibre channel jitter toler-
ance requirements and can recover data signals with
up to 0.7 unit interval (UI) jitter. The circuit’s fully inte-
grated phase-locked loop (PLL) provides a frequency
lock indication and does not need an external reference
clock. These repeaters provide low-jitter CML clock and
data outputs, and are pin compatible with the MAX3770
repeater (except RATESEL pin and exposed paddle).
The MAX3773/MAX3774 can also be used for imped-
ance transformation between 100Ω (differential) and
150Ω (differential) systems. To reduce the number of
external components, all signal inputs and outputs are
internally terminated. The MAX3772–MAX3775 are
available in 16-pin QSOP-EP packages.
