MEMS resonator, two clocks, one tiny package
The DSC2311KI2-R0006 is a MEMS-based XO (standard oscillator) that outputs two fixed frequencies — 12 MHz on output 1 and 20 MHz on output 2 — from a single 6-VDFN package measuring 2.50 mm x 2.00 mm. Unlike a quartz crystal oscillator, the MEMS resonator is less sensitive to shock and vibration, and the dual-frequency output saves a second oscillator footprint on the board.
Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails without an external regulator — the wide range simplifies power-tree design.
