Active production — 38.88 MHz MEMS XO with AEC-Q100 grade
The DSC1001DC5-038.8800T is an active-production MEMS oscillator from Microchip Technology, delivering a 38.88 MHz CMOS output with ±10 ppm frequency stability across its rated temperature range. AEC-Q100 qualification means this part has passed automotive-grade reliability stress tests — suitable for under-hood or cabin electronics where vibration and temperature cycling are routine. The MEMS resonator replaces a quartz crystal, giving the oscillator better shock and vibration tolerance than a conventional crystal oscillator in the same footprint.
Supply voltage and standby function
Supply voltage range spans 1.8 V to 3.3 V, covering the common digital rail voltages without needing an external regulator. A standby (power-down) function on pin 1 drops current consumption to 15 µA max when the oscillator is disabled, useful for battery-powered systems that gate the clock during sleep modes.
Package and mounting for automated assembly
Housed in a 4-SMD no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — a compact footprint that suits space-constrained PCBs in automotive ECUs or portable equipment. Supplied on tape and reel for pick-and-place; the no-lead package requires a solder-paste stencil opening matching the pad layout in the datasheet to avoid tombstoning.
