Output frequencies are 125 MHz, 100 MHz, 100 MHz, and 125 MHz, with ±25 ppm stability across -20°C to 70°C. ## LVPECL output and supply tolerance LVPECL outputs are the differential standard for driving clock trees into FPGAs, high-speed ADCs, and SerDes transceivers. The 2.25 V to 3.6 V supply range covers 2.5 V and 3.3 V rails without an external regulator — useful when the board has mixed logic supplies. ## Package and layout consideration Microchip lists the DSC400-2222Q0022KE2 as Active.","metaTitle":"DSC400-2222Q0022KE2 MEMS XO – Quad LVPECL 125/100 MHz Active","metaDescription":"Microchip DSC400-2222Q0022KE2: MEMS-based XO, LVPECL outputs, 125/100 MHz, ±25 ppm, -20°C to 70°C, 20-VFQFN.
