125 MHz LVDS clock from a MEMS resonator
The DSC1103CI2-125.0000T is a MEMS-based XO (Standard) that outputs a 125 MHz LVDS clock — a common reference for 1 Gigabit Ethernet PHYs, PCIe Gen 1/2, and SerDes transceivers. The LVDS output delivers a differential signal with typical 350 mV swing into a 100-Ω termination, reducing EMI and improving noise immunity on long PCB traces compared to single-ended CMOS clocks.
Supply voltage spans 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails without an external regulator. The 32 mA max supply current at 125 MHz is typical for a MEMS LVDS oscillator at this frequency.
