Overview

The DSC1123CI2-100.0000 is a high-performance MEMS-based differential oscillator providing a stable 100 MHz LVDS output. It operates over a wide supply voltage range of 2.25V to 3.63V and features an enable/disable function for power management in complex systems.

Why Choose This Part

This MEMS oscillator eliminates the need for a quartz crystal, providing superior shock and vibration resistance with +/-25ppm frequency stability. The LVDS output ensures low electromagnetic interference (EMI) and high noise immunity for high-speed signal integrity.

Applications

PCI Express Clocking
Provides a stable 100 MHz reference clock for PCIe Gen 1, 2, and 3 applications requiring low jitter.
Network Switches and Routers
Serves as a reliable timing source for high-speed Ethernet backplanes and communication processors.
FPGA Reference Clock
Acts as a low-noise differential clock source for FPGA transceivers and internal logic synchronization.
Storage Area Networks
Delivers precise timing for Fibre Channel and SAS/SATA interface controllers in data center environments.

Getting Started

To integrate this oscillator, ensure the 6-VDFN landing pattern includes proper bypass capacitors (typically 0.1uF) near the VDD pin. The enable/disable pin (Pin 1) can be interfaced with standard GPIO to reduce system power consumption when the clock is not required.
