MEMS oscillator for wide-temperature clocking
The DSC1101DM2-033.3333 is a MEMS-based XO (Standard) oscillator delivering a 33.3333 MHz CMOS output with ±25 ppm frequency stability. Its 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails without an external regulator.
Standby function and supply current
A dedicated Standby (Power Down) pin pulls the output to high-impedance and drops the supply current to 95 µA max — useful for battery-powered sensors or intermittent-duty transceivers that need to preserve charge between active windows. Active supply current is 35 mA max at 33.3333 MHz, typical for a CMOS-output oscillator at this frequency. The MEMS resonator starts faster than a quartz crystal — no long stabilization wait on power-up.
Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint for space-constrained PCBs. Surface-mount assembly; the 0.50 mm pitch pads require standard fine-pitch soldering profiles. The MEMS die inside is inherently more shock- and vibration-tolerant than a quartz blank — relevant for portable instrumentation and vehicle-mounted electronics where mechanical stress can pull a crystal's frequency.
