What this part is and where it fits
The MAX3770CEE from Maxim Integrated is a fibre channel repeater — a signal-conditioning device designed to regenerate and retime Fibre Channel data streams over longer cable runs or through backplane traces. It sits between the transceiver and the controller, cleaning up jitter and restoring signal amplitude so the link budget closes across the full channel length. This is a physical-layer part for Fibre Channel networks, not a protocol processor or a switch fabric component.
Lifecycle and sourcing reality
The RoHS compliance status is non-compliant, so factor that into BOM regulatory screening — this part contains lead-bearing solder or materials that exempt it from RoHS, which is common for legacy telecom and datacom infrastructure builds where the exemption still applies.
What the RoHS status means for your BOM
RoHS non-compliant means this part cannot be used in new EU-market consumer electronics or medical devices without an exemption claim. For industrial Fibre Channel equipment, repair depots, or military/aerospace builds that are exempt from RoHS, the non-compliant status is often irrelevant or even preferred for solder-joint reliability in high-vibration environments.
