2.125Gbps/1.063Gbps, 3.3V
Fibre Channel Repeaters
General Description
The MAX3770 is a 2.125Gbps Fibre Channel repeater
IC. The MAX3771 provides a pin-compatible solution
for 1.063Gbps Fibre Channel. Both devices are opti-
mized for use in Fibre Channel arbitrated-loop applica-
tions and operate from a 3.3V supply.
The MAX3770 is compatible with Fibre Channel jitter toler-
ance requirements and can recover data signals with up
to 0.7 unit interval (UI) jitter. The circuit’s fully integrated
phase-locked loop (PLL) provides a frequency lock indi-
cation and does not need an external reference clock.
The MAX3770 provides low-jitter CML clock and data
outputs. To reduce the external parts count, all signal
inputs and outputs are internally terminated. The
MAX3770/MAX3771 are available in 16-pin QSOP
packages.
