Unlike a quartz crystal oscillator, the MEMS resonator is immune to vibration-induced frequency shifts and has a faster start-up time — no crystal aging curve to track.
Housed in a 6-VDFN package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The small footprint demands careful PCB layout — ensure the thermal pad is connected to a solid ground plane for heat sinking and to keep the MEMS resonator stable under temperature transients.
The MEMS resonator inside this XO eliminates the crystal aging drift and is more resistant to vibration and shock than a quartz-based oscillator.
The DSC1101 series offers a standby (power-down) function, while the DSC1121 series provides an output-enable (OE) feature. Both are MEMS XOs with the same package and temperature range — the choice depends on whether you need to disable the output or fully power down the oscillator.
