Overview

The DSC1123NI2-125.0000 is a high-performance MEMS-based differential oscillator providing a stable 125 MHz LVDS output. This silicon-MEMS device eliminates the need for quartz crystals, offering superior reliability and mechanical shock resistance in a compact 5.0mm x 3.2mm package.

Why Choose This Part

This oscillator features excellent frequency stability of +/-25ppm across an industrial temperature range of -40degC to 85degC. Its MEMS architecture provides significantly better immunity to vibration and mechanical stress compared to traditional quartz crystal oscillators.

Applications

Gigabit Ethernet Timing
Provides the 125 MHz reference clock required for physical layer transceivers in networking equipment.
Storage Area Networks
Ideal for Fibre Channel and SATA/SAS controllers requiring low-jitter differential signaling.
FPGA Reference Clocks
Serves as a stable, high-frequency heart-beat for FPGAs and high-speed SERDES interfaces.
