Active MEMS oscillator for automotive and industrial timing
The DSC1001AI1-012.2880T is an active-production MEMS-based XO (Standard) delivering a 12.288 MHz CMOS clock from a 1.8V to 3.3V supply rail. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal — relevant for engine-bay ECUs and factory-floor controllers that see continuous mechanical stress.
Standby power and supply flexibility
When the Standby (Power Down) function is asserted, the oscillator draws a maximum of 15 µA — low enough to leave a battery-powered sensor node sleeping for months without draining the cell. Active supply current is 6.3 mA max at full rail, so the total power budget for the timing tree is predictable across the 1.8V to 3.3V range.
The 4-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillator layouts, simplifying a drop-in replacement. Surface-mount assembly with the exposed pad provides a low thermal resistance path to the PCB copper plane, which helps keep the MEMS die temperature stable during rapid ambient changes.
