27 MHz CMOS oscillator — MEMS-based timing in a 3.2×2.5mm package
The ASEM1-27.000MHZ-LC-T: The MEMS resonator replaces the traditional quartz element — it survives mechanical shock and board-level vibration that would crack a quartz blank, making this better suited for industrial automation and motor-drive enclosures where the board is routinely stressed.
Package, supply, and standby current
At 3.3 V nominal the part draws 15 mA maximum during oscillation — but the standby (power-down) function shuts the output and cuts current to 15 µA, so a battery-backed circuit that parks the clock when idle reduces quiescent draw by three orders of magnitude.
