Product details

78.125 MHz LVPECL MEMS clock in a 7×5 mm package

The DSC1122AI1-078.1250T is a Microchip MEMS-based XO (Standard) oscillator delivering a 78.125 MHz LVPECL output from a 2.25V to 3.6V supply rail. 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).
