Operates from 2.25V to 3.6V, covering common 2.5V, 3.0V, and 3.3V rails without an external regulator – simplifies the power tree in mixed-voltage designs.
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of just 0.90mm – the exposed pad aids thermal conduction to the PCB ground plane.
The part carries an Active lifecycle status. Submit an RFQ with your target quantity and target date code – we source through independent distribution and confirm price and lead time at quote.
Yes – the base resonator is MEMS, not quartz. This gives better shock and vibration tolerance compared to a traditional crystal oscillator, which is why the AEC-Q100 rating is relevant for automotive environments.
Yes – the Enable/Disable pin lets the system disable the output. When disabled, the maximum supply current drops from 35mA to 22mA, which helps reduce power in sleep modes.
Yes – the part carries AEC-Q100 rating, meaning it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. It is suitable for under-hood and cabin applications.
