Product details

125.0031 MHz MEMS oscillator with ±25 ppm stability

Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails without an external level translator.

Industrial temperature grade and standby function

Active lifecycle — sourced to order

Product status is Active, meaning Microchip continues production and accepts new orders. The 6-SMD, no-lead package (5.00 mm × 3.20 mm footprint, 0.90 mm seated height) is a standard MEMS oscillator outline, compatible with many existing PCB layouts for 125 MHz oscillators.

Frequently asked questions

Is DSC1101BI2-125.0031T compatible with 3.3V and 2.5V logic?

Yes. The supply voltage range is 2.25 V to 3.6 V, so it operates on both 2.5 V and 3.3 V rails. The CMOS output swings rail-to-rail, matching the logic thresholds of the receiving device at either voltage.

Does DSC1101BI2-125.0031T include a standby power-down function?

Yes, the function is listed as Standby (Power Down). When enabled, the maximum supply current drops to 95 µA, making it suitable for battery-powered designs that need to conserve power during sleep.

Can DSC1101BI2-125.0031T replace a failed 125.0031 MHz oscillator?

Confirm the pinout and standby control polarity against your board schematic.
