MEMS oscillator at 61.44 MHz — why it replaces quartz
The MEMS resonator eliminates quartz crystal aging and start-up reliability issues — no mechanical package to crack or frequency drift from vibration. The supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without a separate regulator. The same BOM line serves mixed-voltage designs — a single oscillator part number across two power domains.
Industrial temperature grade and deployment fit
The 6-SMD no-lead package (7.00mm x 5.00mm) has a seated height of 0.90mm — standard for oscillator footprints. The no-lead land pattern matches the common 7x5 oscillator layout; the board design does not need a via-in-pad or special fan-out.
