Product details

MEMS oscillator at 148.5 MHz — industrial temperature grade

The DSC1101CI1-148.5000T is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a 148.5 MHz CMOS output. The 2.25V to 3.6V supply range covers 2.5V and 3.3V logic rails without an extra regulator — a single rail feeds the oscillator.

Microchip lists the DSC1101CI1-148.5000T as Active.

6-SMD no-lead package — board-fit note

Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The no-lead land pattern is a standard MEMS-oscillator footprint — no via-in-pad required.

Frequently asked questions

Can DSC1101CI1-148.5000T replace a standard quartz oscillator?

Yes — the DSC1101 is a drop-in MEMS replacement for a quartz XO at 148.5 MHz with CMOS output. The MEMS resonator eliminates quartz aging and vibration sensitivity, but the pinout and supply range (2.25V–3.6V) are compatible with most standard oscillator footprints. Confirm the enable/standby logic polarity matches your design.
