Product details

MEMS clock source for industrial temperature zones

The DSC1101CI1-012.5000T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1101 series, delivering a fixed 12.5 MHz CMOS output in a 6-SMD no-lead package.

Supply rail flexibility and board fit

Supply voltage range is 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without an external LDO. The 3.20 mm x 2.50 mm footprint with 0.90 mm seated height fits tight PCB stacks in portable or embedded designs. Surface-mount 6-SMD no-lead package — no through-hole, no socket. The small outline means the oscillator sits directly under a shield can or near the processor without consuming board real estate.

Product status is Active per Microchip's lifecycle records.

Frequently asked questions

Is DSC1101CI1-012.5000T a MEMS oscillator?

Yes. The base resonator is MEMS, not quartz. This means no crystal aging drift, faster start-up, and better shock/vibration tolerance compared to a quartz oscillator, though the frequency stability is still ±50 ppm.

Does DSC1101CI1-012.5000T have a standby (power down) function?

Yes. The standby function disables the output and drops supply current to 95 µA max. This is useful for battery-powered equipment that needs to preserve power during sleep states.

What is the closest pin-compatible alternative to DSC1101CI1-012.5000T?

Within the DSC1101 series, other frequency variants share the same 6-SMD package and pinout — for example, the DSC1101CI1-025.0000T at 25 MHz. The family uses the same MEMS resonator and CMOS output architecture, so a frequency change is the only BOM difference.
