What the PLL and 140 MHz ceiling mean for your board
The 501MILFT is a single-circuit clock multiplier with an integrated PLL, taking a clock or crystal input and delivering a CMOS output up to 140 MHz. The PLL locks to the reference and multiplies it (the divider/multiplier block is No/Yes), so you get a clean, jitter-managed clock without an external VCXO or SAW resonator. For a design that needs a single clean clock at a higher rate than the reference, this part does the job in an 8-pin SOIC footprint that places cleanly on a standard 0.154-inch-wide pad layout.
Package and reflow — will it survive the oven?
Coplanarity is rarely an issue, and the lead pitch (1.27 mm) is wide enough that solder bridging is not a concern even with a standard stencil. No exposed pad or thermal slug means the part dissipates heat through the leads and the small body — at 140 MHz and a few mA of supply current, the die temperature stays well below the 85°C ceiling in most environments. No special thermal vias or copper pours are needed under the package.
