The DSC2311KI1-R0059T is a MEMS-based XO that outputs two independent CMOS clock signals: 25 MHz on output 1 and 12 MHz on output 2, from a single 6-VDFN package measuring 2.50 mm x 2.00 mm.
Operating from 2.25 V to 3.6 V, this oscillator spans 2.5 V and 3.3 V logic rails without a level translator — one BOM line covers both.
The DSC2311 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators are inherently more resistant to shock and vibration, and they typically have shorter startup times. The trade-off is that quartz can sometimes achieve tighter frequency stability over a wider temperature range, though the ±50 ppm stability here is sufficient for most digital clocks.
