The PE1120 series from Pletronics, Inc., is a line of surface-mount crystal oscillators designed for precision timing applications. These devices are commonly used in high-reliability circuits where stability and accuracy are critical, such as in medical equipment, industrial control systems, and telecommunications gear.

If you're working on any project that requires a highly stable clock signal, these oscillators are a go-to choice. They offer excellent frequency stability and low phase noise, making them ideal for applications where jitter must be minimized. One thing worth noting is their compact size; being surface-mount components, they fit seamlessly into modern PCB designs without taking up too much space. Engineers tend to reach for this type of oscillator when they need a reliable and precise time reference without the bulkiness of through-hole components.

Another practical aspect is their ease of integration. With a simple soldering process, they can be easily incorporated into existing designs, reducing the overall complexity and cost of the circuit. The PE1120 series also benefits from the robustness associated with crystal oscillators, providing long-term stability even under varying environmental conditions. Overall, if your application demands a small, stable, and accurate clock signal, the PE1120 series is definitely worth considering.
