Microchip DSC1123DL5-0000: A 200 MHz Ultra-Low Jitter LVDS Oscillator

In the high-speed digital systems of today, from advanced telecommunications infrastructure to high-performance computing clusters, the demand for precise and stable clock signals is paramount. At the heart of such systems lies a critical component: the oscillator. The Microchip DSC1123DL5-0000 stands out as a premier solution, engineered to deliver exceptional performance where timing integrity cannot be compromised.

This device is a 200 MHz LVDS (Low-Voltage Differential Signaling) oscillator that sets a new benchmark for signal clarity and reliability. Its most defining characteristic is its ultra-low jitter performance, specified at a remarkable 150 fs typical (12 kHz – 20 MHz integration range). This exceptionally low phase jitter is crucial for minimizing timing errors in high-speed serial data links, such as those used in 400G Ethernet, OTN (Optical Transport Network), and PCI Express Gen 5/6 applications, where even picoseconds of jitter can significantly impact the bit error rate (BER).

The use of LVDS output offers significant advantages over single-ended alternatives. LVDS provides a low-noise, low-power, and high-speed differential interface that is highly resistant to common-mode noise. This makes the DSC1123DL5-0000 ideally suited for driving high-speed ADCs (Analog-to-Digital Converters), DACs (Digital-to-Analog Converters), FPGAs, and ASICs over potentially noisy board layouts, ensuring a clean clock signal arrives at the destination.

Housed in a compact 5.0mm x 3.2mm 6-pin ceramic package, this oscillator is designed for space-constrained applications without sacrificing performance. It operates from a single 2.5V or 3.3V supply and is characterized for operation over the industrial temperature range (-40°C to +85°C), ensuring robust performance across diverse environmental conditions. Furthermore, it boasts excellent frequency stability of ±25 ppm, guaranteeing consistent operation over its lifetime.

ICGOOODFIND: The Microchip DSC1123DL5-0000 is a high-performance LVDS oscillator that delivers industry-leading ultra-low jitter for the most demanding timing applications. Its combination of 200 MHz frequency, robust differential output, and miniature form factor makes it an indispensable component for designers aiming to achieve maximum signal integrity and system reliability in next-generation high-speed designs.
