Microchip DSC1123CI2-0000: A High-Performance 100 MHz Oscillator for Precision Timing Applications

In the realm of modern electronics, the demand for precise and reliable timing is paramount. From high-speed data communication and network infrastructure to industrial automation and test and measurement equipment, the heartbeat of these systems is governed by a critical component: the oscillator. The Microchip DSC1123CI2-0000 stands out as a premier solution, engineered to deliver exceptional performance for the most demanding precision timing applications.

This device is a 100 MHz, LVDS output oscillator that combines a quartz crystal with a high-performance phase-locked loop (PLL) inside a compact, surface-mount package. The integration of these elements is key to its superior functionality. Unlike traditional crystal oscillators (XO), the DSC1123CI2-0000 leverages its internal architecture to provide a signal with remarkably low phase jitter, a critical parameter for minimizing timing errors in high-speed digital systems. With jitter performance as low as 0.5 ps typical (12 kHz to 20 MHz), it ensures data integrity and reduces the bit error rate (BER) in serial data links.

The oscillator's LVDS (Low-Voltage Differential Signaling) output is another significant advantage. This differential signaling technology offers superior noise immunity compared to single-ended outputs like LVCMOS. This makes the DSC1123CI2-0000 exceptionally resistant to common-mode noise, which is crucial in electrically noisy environments, ensuring a clean and stable clock signal is delivered to the host ASIC, FPGA, or processor.

Furthermore, the device is designed for high stability and reliability. It operates over a wide industrial temperature range (-40°C to +85°C), guaranteeing consistent performance under varying environmental conditions. Its robust construction ensures low sensitivity to external factors such as vibration and electromagnetic interference (EMI). The DSC1123CI2-0000 is also available in a small-footprint 6-pin DFN package, making it an ideal choice for space-constrained PCB designs without compromising on performance.

Key applications for this high-performance oscillator include:

5G Telecom Base Stations and Network Routers: Where low jitter is essential for synchronous data transmission.

Data Center and Cloud Computing Hardware: For clocking CPUs, GPUs, and high-speed SerDes interfaces.

High-Resolution Medical Imaging Systems: Such as MRI and CT scanners, where timing precision directly impacts image quality.

Test and Measurement Equipment: Requiring accurate frequency references for signal generation and analysis.

Industrial Automation and Control Systems: Demanding robust and reliable operation in harsh environments.

ICGOODFIND: The Microchip DSC1123CI2-0000 is a top-tier 100 MHz oscillator that sets a high standard for precision timing. Its exceptional low phase jitter, robust LVDS output, and high reliability make it an indispensable component for designers aiming to achieve maximum performance and signal integrity in advanced electronic systems.
