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.","metaTitle":"DSC1121AI2-131.0750T MEMS XO, 131.075 MHz, AEC-Q100, CMOS","metaDescription":"Microchip DSC1121AI2-131.0750T: MEMS XO, 131.075 MHz, CMOS output, ±25 ppm stability, -40°C to 85°C, AEC-Q100, 6-SMD.
