Product details

MEMS XO – programmable, wide temp, tight stability

The DSC1101CM2-PROG is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a CMOS output across a programmable frequency range of 3.3 MHz to 170 MHz. It ships blank – the user must program the target frequency before use, which means each unit is field-configurable to a single frequency within that range. Supply voltage spans 2.25V to 3.6V, making it compatible with 2.5V and 3.3V logic rails without an external regulator.

Military temp grade and standby function

Package and mounting – 6-VDFN

Housed in a 6-VDFN measuring 3.20mm x 2.50mm with a seated height of 0.90mm – a compact footprint that saves board space in dense layouts.

Frequently asked questions

How do I program the DSC1101CM2-PROG?

The DSC1101CM2-PROG ships blank (unprogrammed). Microchip provides a programming tool and software for the DSC1101 series – typically a programmer dongle and a GUI that writes the desired frequency into the MEMS oscillator's non-volatile configuration registers. Refer to the DSC1101 programming guide for the exact tool chain.

What is the output type and supply voltage of the DSC1101CM2-PROG?

CMOS output. Supply voltage range is 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails.

What is the standby (power down) function?

When the standby pin is asserted, the oscillator stops and the output goes into high-impedance state. This cuts supply current to near-zero, allowing the system to gate the clock during sleep without an external load switch.

Is there a pin-compatible alternative to the DSC1101CM2-PROG?

Within the DSC1101 series, all parts share the same 6-VDFN pinout and supply range. The DSC1101CM2-PROG is the programmable blank variant; fixed-frequency siblings (e.g., DSC1101CI2-xxx.xxxx) are pre-programmed and may suit volume production without a programming step.
