The MEMS base resonator eliminates the quartz start-up and aging drift concerns typical of crystal-based XOs; the 2.25 V to 3.6 V supply range lets it run directly from a 2.5 V or 3.3 V rail without an intermediate regulator. ## ±50 ppm stability over the industrial band ## Active production — no LTB to manage","metaTitle":"DSC400-0202Q0108KI1T MEMS XO – Dual LVPECL Output, ±50 ppm","metaDescription":"Microchip DSC400-0202Q0108KI1T: Dual-frequency LVPECL XO (167.1875 MHz / 173.28125 MHz), ±50 ppm stability, 2.25-3.6 V supply, -40°C to +85°C.
