Oscillators are the foundation of most modern electronic systems, providing a reference clock that powers components, enabling communication and data transfer. The CE3391-12.352 is a PLL frequency synthesizer that produces an exceptionally stable frequency with a wide frequency range. It is a viable option for many applications, including digital communication, telecommunications, and portable consumer electronics.

The CE3391-12.352 is a PLL-based frequency synthesizer whose carrier frequency is provided by a high-frequency crystal oscillator. The PLL acts as a multiplier, multiplying the crystal oscillator frequency to provide the desired output frequency. In addition, an amplitude-controlled PLL-based voltage-controlled crystal oscillator (VCXO) is provided as an alternative reference for frequency applications that require stability and accuracy.

The output range of the CE3391-12.352 is from DC to 1 GHz, with a separate range for the VCXO, which is from DC to 10MHz. Depending on the application, the PLL can be configured for different operating modes, including amplitude-controlled oscillator (ACO), phase-locked loop (PLL), and direct digital synthesizer (DDS).

The CE3391-12.352 features a comprehensive set of programmable features, including an adjustable dynamic power-down mode, phase noise cancellation, and adjustability of loop bandwidth. The power down mode ensures that the synthesizer does not draw current when it is not in use, and the phase noise cancellation helps to reduce noise when using the device for higher frequency applications. The adjustable loop bandwidth allows for optimization in terms of frequency accuracy, phase noise, and leakage reject.

In addition, the CE3391-12.352 utilizes a low-noise front-end PLL technique to achieve high output frequency accuracy as well as low jitter. The PLL also employs a dual-loop architecture, allowing for lower noise and greater spur immunity. The frequency tuning step of the device is as low as 0.1Hz, and the frequency tolerance is as high as +/-1mHz.

The CE3391-12.352 is suitable for a variety of communication and telecommunication applications, including digital broadcast systems, satellite systems, wireless communication systems, and multiple access systems. It is also suitable for consumer devices, such as cordless phones, navigation systems, and mobile base stations.

In summary, the CE3391-12.352 is a high-performance, versatile PLL frequency synthesizer with wide operating frequency range and excellent frequency stability. It is well-suited for applications requiring low jitter, high output frequency accuracy, and low phase noise. The adjustable loop bandwidth, low noise techniques, and power down mode make it a great choice for high-quality, efficient frequency synthesis.
