AEC-Q100 qualification and an industrial temperature range of -40°C to 85°C make it suitable for under-hood automotive modules, outdoor telecom equipment, and factory-floor controllers where temperature swings and vibration are routine. ## Supply voltage and frequency stability for the BOM The 1.71V to 3.63V supply range covers both 1.8V and 3.3V logic rails without a level translator — a single oscillator feeds a 1.8V MCU and a 3.3V peripheral on the same clock tree. ±50 ppm frequency stability across the full temperature band keeps the clock edge jitter within the timing budget for a 745 kHz CAN bus or UART bit clock — no external trim capacitor needed. Typical supply current is 1.3 mA — low enough for battery-backed RTC or always-on wakeup domains in automotive body controllers. ## Package and mounting for production Housed in a 4-VFLGA (1.60mm x 1.20mm) surface-mount package with a seated height of 0.89 mm — the small footprint suits space-constrained PCBs in camera modules, key fobs, or sensor pods. The Enable/Disable function lets the system pull the output to high-Z for power savings during sleep modes — the MEMS resonator itself stays biased, so startup latency is avoided on re-enable. ## Lifecycle and sourcing position Suitable for both new designs and ongoing production builds. Quoted to order against the BOM quantity. No pin-compatible second source is listed in the DSC60XXB series; the DSC6003HI1B-745K000 is the specific frequency and grade variant.","metaTitle":"DSC6003HI1B-745K000 MEMS XO, 745 kHz, AEC-Q100, Active","metaDescription":"Microchip DSC6003HI1B-745K000 MEMS XO, 745 kHz CMOS output, AEC-Q100 qualified, -40°C to 85°C, 1.71V-3.63V supply.
