MEMS resonator for shock-tolerant timing
Output is LVPECL, a differential signal that rejects common-mode noise and maintains clean edges over longer PCB traces or through a backplane, making it a fit for high-speed clock distribution at 40 MHz.
±10 ppm stability across industrial temperatures
Supply voltage spans 2.25V to 3.6V, so it can run off a 2.5V or 3.3V rail without a separate regulator, simplifying the power tree.
It is safe to design in for new production and to replenish against existing BOM positions. The 6-SMD, no-lead package (3.20 mm x 2.50 mm, 0.90 mm seated height) is a standard oscillator footprint that places cleanly with pick-and-place and reflows without tombstoning risk at the typical 260°C peak profile.
Standby function for power-sensitive designs
When enabled, the oscillator draws 58 mA max at 40 MHz — typical for an LVPECL output at this frequency; the differential swing consumes more current than a single-ended CMOS oscillator, but the noise immunity often justifies it.
