MEMS XO for automotive and industrial timing
The DSC6003HI1B-745K000 is a MEMS-based XO (Standard) delivering a 745 kHz CMOS output — a fixed-frequency clock for microcontrollers, CAN transceivers, or sensor interface ASICs that need a stable reference without a quartz crystal's external load capacitors. 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.
