Operates from 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an external regulator — the Enable/Disable function lets the system gate the outputs for power sequencing or test modes. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height) — the thermal pad should be soldered to a ground-plane island for heat sinking and to keep the MEMS resonator's frequency stable under airflow.","metaTitle":"DSC400-3333Q0099KE1 MEMS XO – Microchip, 4-output LVDS","metaDescription":"DSC400-3333Q0099KE1 MEMS XO from Microchip: LVDS, 4 outputs (148.35/148.5/156.25/208.333/197.8/198 MHz), ±50 ppm, 2.25-3.6V, -20°C to 70°C.
