Microchip DSC1123AE1-0000T: A 100 MHz Low-Jitter LVDS Oscillator

In the realm of high-speed digital systems, signal integrity is paramount. Clock sources, the heartbeat of these systems, must deliver exceptional precision and stability to ensure error-free data transmission and processing. The Microchip DSC1123AE1-0000T stands out as a premier solution, engineered to meet the rigorous demands of modern applications with its 100 MHz Low-Jitter LVDS output.

This oscillator belongs to Microchip's family of Discera® Silicon Oscillators, which leverage advanced MEMS (Micro-Electro-Mechanical Systems) technology. Unlike traditional quartz-based oscillators, this silicon approach offers superior resilience against environmental stressors such as shock, vibration, and electromagnetic interference (EMI). This inherent robustness makes the DSC1123AE1-0000T an ideal choice for challenging operating conditions in industrial, automotive, and communications infrastructure.

The defining feature of this component is its exceptionally low phase jitter, specified at a remarkable 0.5 ps (typical) for offsets from 12 kHz to 20 MHz. Low jitter is absolutely critical for high-speed serial interfaces like PCIe, SATA, and 10G/40G/100G Ethernet, as it minimizes timing errors and reduces the bit error rate (BER), thereby enhancing overall system performance and reliability.

Furthermore, the device utilizes Low-Voltage Differential Signaling (LVDS). This output type offers significant advantages over single-ended formats like LVCMOS. LVDS provides a low-amplitude, differential signal that is highly resistant to common-mode noise, reduces electromagnetic emissions (EMI), and enables higher speed operation with lower power consumption. The 100 MHz frequency provided by this specific model is a common and fundamental clock frequency used for clocking processors, FPGAs, and ASICs, as well as serving as a reference for frequency synthesizers.

Housed in a compact 5.0mm x 3.2mm surface-mount package, the oscillator supports an industrial temperature range from -40°C to +85°C, ensuring consistent performance across a wide array of applications. Its industry-standard footprint allows for easy drop-in replacement for existing quartz oscillators, facilitating straightforward design upgrades for improved performance.

ICGOOODFIND: The Microchip DSC1123AE1-0000T is a high-performance, MEMS-based LVDS oscillator that delivers outstanding jitter performance and signal integrity. Its combination of robustness, low power, and a compact form factor makes it an superior choice for designers aiming to boost the reliability and performance of their high-speed digital systems.
