The integrated circuit (IC) of SI4112-BT is specially designed for digital applications, such as servers, routers, switches, and network devices that require precise clock and data synchronization. The low-jitter performance of this device and its auto-locked calibration options make it a popular choice for high-precision timing applications.

SI4112-BT is based on the standard digital synthesis-based PLL technique, which uses a signal and an external reference clock to generate a highly precise internal signal in the frequency domain. The device has a set of four programmable output frequency dividers allowing the precise frequency of the outputs to be adjusted according to the desired application requirements. The outputs of the device also feature an integrated output driver that eliminates the need for a separate circuit driver.

Additionally, the SI4112-BT has the ability to track inputs with various clock hemispheres, allowing for the clock output signals to stay in lock with their reference source. For stable output performance, the device is also equipped with advanced calibration features that provide for fast and stable output. To optimize the time base accuracy of the device, the calibration algorithm also provides for a wide variety of test points with individually adjustable jitter suppression.

In addition to its features, the device also features an integrated clock output driver that provides an output signal with very low jitter. The clock outputs are driven by the PLL with a power supply of 1.8 V and can be adjusted with external control pins. It also includes over-temperature protection and a built-in thermal shutdown for reliable operation.

The SI4112-BT is a versatile device that delivers outstanding performance in a wide range of applications. It is well suited for clock synchronization in telecommunications systems, wireless networks, industrial automation networks, and general boundary-scan applications. In addition to being used as a clock generator, it can also be used as a frequency synthesizer and oscillator. As a result, it has become a popular choice for many timing tasks requiring highly precise clock and data synchronization.
