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.","metaTitle":"DSC1030BI1-014.7456T MEMS XO 14.7456 MHz CMOS - Microchip","metaDescription":"DSC1030BI1-014.7456T: Microchip PureSilicon™ MEMS oscillator, 14.7456 MHz, CMOS output, 3V supply, ±50 ppm stability, -40°C to 85°C, 4-SMD.

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."},{"question":"What output type and supply voltage does DSC1030BI1-014.7456T use?","answer":"CMOS output, 3V supply.
