The DSC1102DI2-125.0000 is a Microchip DSC1102-series MEMS-based XO delivering a 125 MHz LVPECL output — the differential signal keeps jitter low over the 2.25V to 3.6V supply range, which matters when clocking a SerDes or FPGA transceiver that needs a clean reference.
The two share the same DSC1102 series, package (6-SMD no-lead), supply range, and pinout — the only difference is frequency (125 MHz vs 100 MHz). If the downstream logic can accept 125 MHz, the replacement is pin-compatible; otherwise a clock divider or PLL reconfiguration may be needed.
LVPECL — a differential positive-referenced emitter-coupled logic output. It provides a clean, low-jitter square wave suitable for driving 50-ohm terminated transmission lines at 125 MHz.
2.25V to 3.6V — the wide range allows it to run from a 2.5V or 3.3V rail without an extra regulator. The LVPECL output swing scales with the supply, so check the receiver's input threshold at the chosen Vdd.
