The MAX3771 provides a pin-compatible solution for 1.063Gbps Fibre Channel. Both devices are optimized for use in Fibre Channel arbitrated-loop applications and operate from a 3.3V supply. The MAX3770 is compatible with Fibre Channel jitter tolerance 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 indication 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.
