It accepts any supply from 1.8V to 3.3V, so the same part number works across 1.8V, 2.5V, and 3.3V logic domains without a separate regulator. ## Automotive-grade reliability, commercial temperature band The 4-SMD, no-lead package (5.0 mm × 3.2 mm, 0.9 mm seated height) is a common footprint shared by many MEMS and quartz oscillators, easing board layout. ## Active lifecycle – sourcing per BOM No pin-compatible second source or successor is documented — the DSC1001 family is the only direct reference.","metaTitle":"DSC1001BE5-044.0000 MEMS Oscillator – 44 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001BE5-044.0000: 44 MHz MEMS XO, CMOS output, ±10 ppm stability, 1.8-3.3 V supply, AEC-Q100 qualified.

The active supply current is 7.2 mA max at 44 MHz."},{"question":"Can DSC1001BE5-044.0000 replace a quartz oscillator?","answer":"Yes, it is a MEMS-based drop-in replacement for a 44 MHz quartz XO in the same 4-SMD footprint. The MEMS resonator offers better shock and vibration tolerance than quartz, but check the ±10 ppm stability against your system's timing budget."},{"question":"What is the frequency stability of DSC1001BE5-044.0000?","answer":"±10 ppm over the full -20°C to 70°C range. This is tighter than a typical ±25 ppm quartz oscillator and sufficient for most serial communication and processor clock applications."},{"question":"What is the output type of DSC1001BE5-044.0000?","answer":"CMOS — a single-ended, rail-to-rail output that directly drives most logic inputs without level translation."},{"question":"Is DSC1001BE5-044.0000 AEC-Q100 qualified?","answer":"Yes, it carries an AEC-Q100 rating, meaning it has passed automotive-grade stress tests.
