Product details

MEMS oscillator replaces quartz at 14.7456 MHz

The DSC1030BI1-014.7456T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 14.7456 MHz CMOS output from a 3V supply rail. Unlike a quartz crystal oscillator, the MEMS resonator is immune to vibration-induced frequency jumps and starts up faster — useful in portable or industrial gear where a quartz can would be a mechanical weak point.

Power budget: 3 mA active, 1 µA standby

Maximum supply current is 3 mA (typical) while oscillating, and drops to 1 µA when the standby (power-down) function is asserted. For a battery-powered sensor logging data once per second, the oscillator's active duty cycle is short enough that the 1 µA standby dominates the average — so the system sleep current stays under the microcontroller's own deep-sleep floor.

Footprint and temperature range

Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — the same footprint as a standard 5x3.2 mm quartz oscillator.

Frequently asked questions

Is DSC1030BI1-014.7456T a direct drop-in replacement for a quartz crystal oscillator?

Footprint-compatible with standard 5.0 mm x 3.2 mm 4-pad quartz oscillators, but the internal resonator is MEMS, not a quartz crystal. The electrical interface (CMOS output, 3V supply, standby pin) is the same; however, the MEMS start-up time is typically under 5 ms versus 10-20 ms for a quartz oscillator. If your design relies on the slower ramp of a quartz part for power-on sequencing, verify the downstream logic's reset timing.

What output type and supply voltage does DSC1030BI1-014.7456T use?

CMOS output, 3V supply. The output swings rail-to-rail CMOS levels, so it interfaces directly with 3.3 V logic families (the high-level output is within the VOH threshold of a 3.3 V input). No external level translator is needed.
