Product details

131.075 MHz MEMS oscillator for automotive and industrial timing

Its AEC-Q100 qualification means this oscillator is tested and rated for automotive-grade reliability — suitable for under-hood ECUs, ADAS sensor modules, and chassis-domain controllers where temperature cycling and vibration are routine. The wide supply range of 2.25V to 3.6V allows it to run from a common 3.3V or 2.5V rail without an extra LDO, simplifying the power tree in mixed-voltage designs.

MEMS resonator vs quartz — what the spec means for your BOM

The base resonator is MEMS, not quartz — this gives inherent shock and vibration immunity compared to a quartz crystal, which matters for automotive and industrial environments where mechanical stress can cause quartz to fracture or frequency shift. Maximum supply current is 35 mA when enabled and 22 mA when disabled — the disable function (Enable/Disable pin) lets the system cut oscillator power during sleep modes, saving over a third of the active current. The 6-SMD package with no lead and exposed pad (7.00mm x 5.00mm footprint, 0.90mm seated height) is a standard oscillator land pattern — no special layout considerations beyond the usual decoupling cap near the supply pin.
