The ±50 ppm frequency stability and Enable/Disable function make it a drop-in clock source for high-speed serial links, FPGA reference clocks, and SerDes applications where LVPECL levels are required. The 2.25V to 3.6V supply range covers both 3.3V and 2.5V rails without an external regulator — confirm the rail stays within this window at the load current (58 mA max, 22 mA in disable). ## Active lifecycle — production and sourcing posture ## MEMS resonator — vibration tolerance and reliability","metaTitle":"DSC1122AI1-078.1250T Microchip MEMS XO, 78.125 MHz LVPECL","metaDescription":"DSC1122AI1-078.1250T: Microchip DSC1122 series MEMS XO, 78.125 MHz, LVPECL output, 2.25-3.6V, -40 to 85°C, 6-SMD.
