Product details

The DSC1121DM2-014.7456T is a MEMS-based XO (standard oscillator) from Microchip's DSC1121 series, delivering a 14.7456 MHz CMOS output with ±25 ppm frequency stability.

Supply flexibility and enable control

The 2.25V to 3.6V supply range lets this oscillator serve 2.5V, 3.0V, and 3.3V logic domains without a separate regulator — one BOM line covers multiple rail voltages.

6-VDFN package and board layout

Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator fits tight PCB real estate. The 0.90 mm profile allows placement under low-clearance enclosures or on the back side of a board.

Frequently asked questions

Can the DSC1121DM2-014.7456T replace a standard quartz crystal oscillator?

Yes, it is a drop-in replacement for a 14.7456 MHz quartz XO with CMOS output and Enable/Disable function, provided the board is designed for a 6-VDFN package (2.50 mm x 2.00 mm). The MEMS resonator offers better shock resistance (tested to 50,000 g) and faster start-up than quartz, making it a preferred choice for ruggedized designs.

Is the DSC1121DM2-014.7456T RoHS compliant?

The part is listed as RoHS compliant per Microchip's standard material declaration. No specific exemption or non-compliance has been noted in the product documentation.
