Product details

MEMS oscillator at 14.7456 MHz — CMOS output, ±25 ppm

The DSC1101CI2-014.7456T is a MEMS-based XO (Standard) producing a 14.7456 MHz CMOS clock. The MEMS resonator replaces the quartz crystal, which typically means faster lead times and better shock/vibration tolerance compared to a conventional quartz oscillator — a practical advantage when the BOM calls for a reliable clock source without the long procurement cycles of custom-tuned quartz parts.

Supply range and standby power-down

The oscillator operates from a single 2.25V to 3.6V supply, covering 2.5V and 3.3V rails without an external regulator. Maximum supply current is 35 mA during active oscillation. A Standby (Power Down) function on pin 1 disables the output and drops the supply current to 95 µA max — useful for battery-powered equipment that gates the clock during sleep modes.

There is no last-time-buy window or obsolescence notice in force — the part can be designed into new builds without a short-lifecycle risk.

Frequently asked questions

What is the output type of DSC1101CI2-014.7456T?

CMOS. The DSC1101CI2-014.7456T outputs a standard CMOS-level square wave at 14.7456 MHz, compatible with most digital logic families and MCU clock inputs.

Can DSC1101CI2-014.7456T be used as a drop-in replacement for a standard quartz XO?

Functionally yes — same 14.7456 MHz frequency, same CMOS output, same 6-SMD footprint. The MEMS resonator inside is more robust against vibration and has a faster startup time than a quartz crystal oscillator. Confirm the pin 1 logic level for the standby function matches your board's enable scheme.
