The SI5338C-B08927-GMR is a low-jitter frequency synthesizer specially developed for applications in the telecommunications, data communication, radar and instrumentation markets. By combining a 32 kHz crystal with an integrated voltage controlled oscillator (VCO) and an internal digital phase frequency detector, the SI5338C-B08927-GMR can output frequencies from 0 to over 200 MHz.

The SI5338C-B08927-GMR is suitable for a variety of digital communication and synchronization tasks. The primary application field for this device is the generation of multiple, low phase noise frequencies and the synchronization of digital signal transfers in the wireless, base station and network infrastructure.

In addition, the design of the SI5338C-B08927-GMR allows it to serve various timing and synchronization functions such as setting up and monitoring the clocking of integrated circuits, synchronizing the internal and external clocks of an oscilloscope, or extracting the clock derived from incoming data streams. Additionally, the low jitter of the SI5338C-B08927-GMR makes it ideal for enterprise, medical and broadcasting equipments, as it can help to reduce the impact of the network jitter on signal integrity and accuracy.

At the core of the SI5338C-B08927-GMR is a voltage-controlled oscillator (VCO) capable of producing frequencies from 2 kHz to over 200 MHz. The device is programmed via an I2C-compatible serial interface, allowing for easy adjustment or reconfiguration of all settings. The SI5338C-B08927-GMR also integrates a phase-frequency detector, digital feedback control loop and frequency dividers which enable it to achieve exceptionally low jitter of just under 1.5 ps over a frequency range from 0.711 to 125 MHz.

The working principle of the SI5338C-B08927-GMR is quite straightforward. When the device is powered-up, it attempts to locate the center frequency at which it can match the externally supplied reference frequency. The device then locks onto this frequency and begins to divide down to generate the required output frequencies. The SI5338C-B08927-GMR includes several built-in features to ensure accurate and stable results such as a feedback signal cleaning circuit and temperature compensation.

Overall, the SI5338C-B08927-GMR is an ideal solution for any application requiring the generation of multiple, low-jitter clock frequencies in the 0-200 MHz range. Its ability to generate a wide range of frequencies and its low jitter performance make it an attractive option for such applications as telecommunications, data communications, radar and instrumentation as well as for general frequency synthesis. In addition, the integrated digital phase frequency detector and feedback control loop allow the device to accurately lock onto a wide variety of reference frequencies, allowing the SI5338C-B08927-GMR to easily adapt to changing or unusual clock requirements.
