Overview

The DSC1123BI2-100.0000 is a high-performance 100 MHz LVDS oscillator based on MEMS resonator technology. It provides a stable differential output across a 2.25V to 3.63V supply range and is housed in a compact 5.0mm x 3.2mm 6-VDFN package. This device is designed to replace traditional quartz crystal oscillators in environments requiring high reliability and frequency stability.

Why Choose This Part

The MEMS-based architecture offers superior reliability and shock resistance compared to quartz oscillators, maintaining +/-25ppm stability over a -40C to +85C range. The LVDS output ensures low electromagnetic interference (EMI) and high noise immunity for sensitive high-speed digital circuits.

Applications

High-Speed Networking
Provides the 100 MHz reference clock for Ethernet switches and routers requiring low-jitter LVDS signaling.
FPGA Clocking
Serves as a precise differential clock source for FPGA transceivers and logic fabrics.
Storage Area Networks
Ideal for Fibre Channel and SAS/SATA interfaces in data center storage equipment.
PCI Express Timing
Acts as a stable frequency source for PCIe Gen 1/2/3 based systems.

Getting Started

When integrating this oscillator, place a 0.1uF bypass capacitor as close as possible to the VDD pin and ensure the LVDS output is terminated with a 100-ohm differential resistor at the receiver. Since this is a MEMS device, it does not require the external load capacitors typically associated with crystal resonators.
