This dual-frequency architecture lets one oscillator feed two clock domains — for example, a 27 MHz reference for a USB PHY and a 54 MHz core clock — reducing component count and board area compared to using two separate oscillators. ## Industrial temperature and tight stability The ±25 ppm frequency stability holds across the full temperature and supply range (2.25 V to 3.6 V), keeping clock jitter within the timing budget for 100BASE-TX and CAN-FD interfaces. ## 6-VDFN package and enable/disable function Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a 0.90 mm seated height, the oscillator fits tight PCB layouts in portable or multi-layer designs. The Enable/Disable pin (function) allows the outputs to be tri-stated, reducing supply current to 23 mA max when disabled — useful for power-gating clock trees during sleep modes.","metaTitle":"DSC2311KL2-R0018 MEMS XO – 27 MHz & 54 MHz CMOS, Active","metaDescription":"Microchip DSC2311KL2-R0018 dual-output MEMS oscillator: 27 MHz and 54 MHz CMOS, ±25 ppm, -40 to 105 °C, 6-VDFN.

The supply voltage range is 2.25 V to 3.6 V, so it works directly on 3.3 V and 2.5 V rails without an external regulator. The CMOS outputs swing rail-to-rail, ensuring logic-level compatibility with 3.3 V and 2.5 V devices."},{"question":"What is the output type of the DSC2311KL2-R0018?","answer":"The outputs are CMOS (single-ended), compatible with standard digital logic inputs.
