Overview

The DSC1103CI5-300.0000 is a high-performance MEMS oscillator from Microchip Technology designed to provide a stable 300MHz LVDS output. It utilizes a silicon MEMS resonator to eliminate the reliability issues common with traditional quartz crystals, offering superior shock and vibration resistance. This device operates across an industrial temperature range of -40C to +85C with a stability of 50ppm.

Why Choose This Part

The MEMS-based architecture provides excellent long-term reliability and is 20 times more resistant to mechanical shock and vibration than quartz. Its LVDS output ensures low electromagnetic interference and high signal integrity over 300MHz traces, while the 3.2x2.5mm package saves significant PCB real estate.

Applications

High-Speed Networking
Ideal for 10/40/100G Ethernet, Fibre Channel, and InfiniBand clocking where low jitter LVDS signaling is required.
FPGA Clocking
Provides a clean differential reference clock for high-speed serial transceivers and internal FPGA logic.
PCI Express Timing
Suitable for PCIe Gen 1/2/3/4 system clocks that demand stable high-frequency oscillation in compact form factors.

Getting Started

To integrate this oscillator, ensure a clean 2.25V to 3.6V supply and place 0.1uF bypass capacitors close to the VDD pin. The LVDS output should be terminated with a 100-ohm differential resistor at the receiver side for optimal signal performance. Evaluation can be performed using standard MEMS oscillator breakout boards or by ordering customized samples through the Microchip ClockWorks online configurator.
