Overview

The DSC1123CI5-100.0000 is a high-performance 100 MHz MEMS oscillator featuring an LVDS output stage. It is designed to provide a stable clock source with +/-10ppm frequency stability across a wide temperature range of -40C to +105C, utilizing a silicon MEMS resonator instead of a traditional quartz crystal. This device operates from a supply voltage of 2.25V to 3.63V in a compact 3.2mm x 2.5mm VDFN package.

Why Choose This Part

The MEMS-based architecture offers superior reliability and resistance to mechanical shock and vibration compared to quartz oscillators. Its LVDS output ensures low electromagnetic interference (EMI) and high noise immunity for high-speed signal integrity. The tight +/-10ppm stability and extended temperature range up to 105C make it ideal for demanding industrial and telecommunications applications.

Applications

High-Speed Networking
Provides a low-jitter reference clock for 10GbE, Fibre Channel, and InfiniBand communication interfaces.
FPGA Clocking
Acts as a stable differential clock source for high-performance FPGA and ASIC logic blocks requiring LVDS signaling.
PCI Express Timing
Suitable for PCIe Gen 1, 2, and 3 clocking requirements in storage and server backplanes.
Industrial Computing
Reliable timing for embedded systems operating in harsh environments with high vibration or wide temperature swings.

Getting Started

When integrating this oscillator, place a 0.1uF bypass capacitor as close as possible to the VDD pin to minimize supply noise. The LVDS output requires standard 100-ohm differential termination at the receiver side for proper signal integrity. Engineers can use the Enable/Disable function on pin 1 to manage power consumption in sensitive designs.
