125 MHz MEMS oscillator with LVCMOS output
That 125 MHz rate is a common reference for Gigabit Ethernet PHYs, FPGA transceivers, and high-speed serial interfaces — one less PLL multiplication stage in the clock tree.
Industrial temperature range and low power draw
No need to step up to a wider-range military part for those environments.
4-VFLGA package — footprint and layout
Housed in a 4-VFLGA package measuring 2.00 mm x 1.60 mm with a seated height of 0.89 mm. That is a small land-grid array — the four pads are on the bottom, so the PCB footprint is a simple 2×2 array with a keep-out zone for the body. No via-in-pad required; a standard micro-via fan-out works.
