MAX3773CEE+
MAX3773CEE+ Datasheet
The are dual-rate 1.0625Gbps and 2.125Gbps fibre channel repeaters. They are optimized for use in fibre channel arbitrated loop applications and operate from a +3.3V supply. The exceed fibre channel jitter tolerance requirements and can recover data signals with up to unit interval UI jitter. The circuit’s fully integrated 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 impedance transformation between differential and differential systems. To reduce the number of external components, all signal inputs and outputs are internally terminated. The are available in 16-pin QSOP-EP packages.
