The DSC1123AE2-300.0000 is a MEMS-based XO (Standard) delivering a 300 MHz LVDS output with ±25 ppm frequency stability across its -20°C to +70°C operating range. The LVDS signalling keeps jitter low for high-speed serial interfaces such as Gigabit Ethernet, PCIe, and SerDes reference clocks, where a quartz oscillator's startup time or vibration sensitivity can cause link retraining. AEC-Q100 qualification extends the part's suitability to automotive domains — infotainment head units, camera modules, and ADAS sensor fusion boards that must hold clock integrity under engine vibration and thermal cycling. The MEMS resonator inherently withstands 50,000 g shock and 70 g vibration, a reliability margin quartz cannot match without additional packaging.
The supply voltage range spans 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails common in mixed-signal designs.
This is a design-in grade part — no last-time-buy window to manage, no forced migration to a successor. The 6-SMD, no-lead exposed-pad package is a standard 7.0 mm × 5.0 mm footprint shared across the DSC1123 family, simplifying second-source qualification if needed.
