Additionally, its high frequency input allows it to be used as a PLL component in high-speed systems.

Now, let\'s take a look at the working principle of this device. The SI52111-B3-GTR features an automatic frequency control loop (AFC) which is capable of detecting and correcting slight but perceptible frequency discrepancies. This is accomplished by receiving a reference clock signal and comparing it to the clock output. Any detected difference is used to adjust the output frequency accordingly, thus resulting in extremely accurate synchronization.

The SI52111-B3-GTR is also able to track multiple reference clocks. This is especially advantageous in applications where the system needs to stay synchronized with multiple sources, such as base stations in a cellular network. This device can also operate in a lock-free, open-loop manner, in order to eliminate any additional latencies for applications requiring reduced latency.

The SI52111-B3-GTR is also capable of providing a range of output frequencies, such as 2MHz, 5MHz, 10MHz and 20MHz, with very low jitter performance, as low as 0.25ps. This makes it an excellent choice for applications requiring very high clock precision and accuracy. For applications requiring even higher accuracy, it is also possible to apply temperature drift compensation, making the device even more reliable.

The SI52111-B3-GTR is also highly configurable. It features a wide range of programming options, allowing it to be configured to meet the specific needs of each application. This includes options such as the ability to set holdover times, switch thresholds and clock input thresholds, as well as other relevant parameters.

In summary, the SI52111-B3-GTR is an excellent choice for a wide range of clock-timing applications. It is a highly-configurable, low-cost device with a range of useful features. It is suitable for applications ranging from local system integrated circuits to global communications devices, and can track multiple reference clocks for very precise synchronization. With its wide range of application capabilities, the SI52111-B3-GTR is an ideal choice for system designers looking for a reliable, cost-effective clock-timing solution.
