Outputs are configured as 125 MHz, 100 MHz, 100 MHz, and 125 MHz, covering the two most common reference frequencies for 1GbE MAC/PHY pairs and PCIe root complexes. ## Lifecycle and supply: active, no EOL watch ## Supply voltage and enable logic Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without an external regulator. ## Package and layout note","metaTitle":"DSC400-2222Q0022KE2T MEMS XO","metaDescription":"Active quad-output MEMS oscillator from Microchip.
