What this 1:4 fanout buffer does on your clock tree
The IDT 524MILFT is a single-circuit fanout buffer from the ClockBlocks™ family that takes one clock input and distributes it to four CMOS outputs. It handles clock frequencies up to 200 MHz, making it a straightforward choice for splitting a reference clock to multiple loads — FPGA banks, multiple ADCs, or a set of SerDes transceivers — without adding differential routing complexity. The non-differential input and output (No/No) mean you feed it a single-ended clock and get back four single-ended CMOS copies.
Supply range and temperature — where it fits on the board
The 2.375V to 5.25V supply range covers 2.5V, 3.3V, and 5V logic rails without a separate regulator. That wide compliance simplifies BOM consolidation when the board already runs mixed-voltage domains. The -40°C to 85°C operating temperature covers industrial environments — outdoor telecom cabinets, factory-floor controllers, and base-station line cards — without needing an extended-temperature variant.
8-SOIC package — rework-friendly and board-fit
The 8-SOIC package (0.154" body width, 3.90 mm) is a standard footprint that hand-rework handles easily. No thermal pad underneath, so no via-stitch requirement — just a clean, two-layer-routable layout. Will it survive the hot air? Yes, with a standard 260°C peak profile and no moisture sensitivity surprises (MSL 1 typical for this package class).
Lifecycle and compliance — active, no LTB clock ticking
The 524MILFT carries an Active product status and is ROHS3 compliant. No last-time-buy notice, no NRND flag. For a production BOM line, this part is a stable, current-generation choice — no forced redesign cycle looming.
