The 4 kHz CMOS output is unusually low for a MEMS oscillator, making it a fit for low-speed clocking roles such as a watchdog timer reference or a sleep-mode clock where power draw is critical.
The part operates from 1.71 V to 3.63 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without needing a separate regulator. Frequency stability is ±20 ppm across that range — enough for UART baud-rate generation or a low-speed reference where tighter ppm is not required.
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm, the oscillator is a surface-mount component suited for automated pick-and-place. The small footprint frees board space in dense designs.
