What the speed-switching clock generator does on the board
The MAX7391CMTP is a speed-switching clock generator — it produces a clock output that can shift between two preset frequencies, typically used to throttle a processor or peripheral between full-speed and low-power operating modes without a separate oscillator for each state.
Active lifecycle and compliance reality
It is RoHS non-compliant — the lead content in the solder finish or die-attach means this part cannot ship into RoHS-restricted regions without an exemption, and any BOM that requires RoHS compliance will need an alternative or a waiver.
Packaging and procurement note
Supplied in Bulk — loose tubes or trays rather than tape-and-reel, which suits engineering samples, prototype runs, and small-lot repair orders where a reel quantity would be wasteful.
