It outputs one 12 MHz and three 50 MHz lanes (LVCMOS or LVDS), cutting BOM line count and board area. The MEMS resonator eliminates the quartz start-up time and frequency-pull issues typical of crystal oscillators; the part is Enable/Disable controlled, letting the system gate unused outputs during low-power modes. ## Supply rail and temperature envelope Supply range 2.25 V to 3.6 V covers both 2.5 V and 3.3 V logic rails without an intermediate regulator. Frequency stability is ±50 ppm over the full temperature and supply range, tight enough for most Ethernet PHY reference clocks and FPGA transceiver PLLs. ## Package and board-fit note 20-VFQFN with exposed pad (5.00 mm × 3.20 mm, 0.90 mm height). Standard tube shipment. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC400-3331Q0098KE1 MEMS XO – Quad Output 12/50 MHz, Active","metaDescription":"Microchip DSC400-3331Q0098KE1 MEMS XO, 4 outputs (12 MHz + 3×50 MHz), LVCMOS/LVDS, 2.25-3.6 V, -20 to 70°C.
