The SI5335B-B05151-GM Clock Generator is suitable for multiple application fields including datacenter switches, network routers and storage products. It\'s also ideal for consumer products such as televisions, home theater systems, vending machines, and portable handheld cameras, as well as for industrial monitoring systems and analog-to-digital converter clock sources.

Working Principle

The SI5335B-B05151-GM Clock Generator works by using an external crystal as its reference clock source. When an external crystal is detected, the internal VCXO is enabled and the PLL of the device will take the low-frequency reference clock as an input. The PLL outputs a digitally controlled oscillator (DCO) signal usable by the system clock generator. The DCO is a high frequency clock signal that is capable of generating a range of output clocks. The frequency of the DCO signal is controlled by selecting the desired output frequency using the provided programming instructions.

The PLL works to lock the output clock frequency to the desired setting. Once the PLL is locked, the system clock generator uses the DCO signal as its clock source. It also uses the buffered 25MHz as its low-frequency reference for clock multiplication. The system clock generator will then produce the desired output clock frequencies.

The user can program the frequency of the output clocks and the phase of the outputs. This allows the device to be used for a variety of applications and can be customized to suit customer requirements. Furthermore, it has an integrated low jitter crystal oscillator for reliable, low-jitter clock generation.

In order to achieve the best performance, the SI5335B-B05151-GM Clock Generator should be placed close to the application board. This will help reduce board trace delays, thereby optimizing system performance. Additionally, a proper printed circuit board layout should be followed to ensure proper operation.

The SI5335B-B05151-GM Clock Generator is an ideal solution for generating a range of reliably timed output clocks perfect for multiple applications. With its low power consumption, excellent signal quality and superior performance, it provides a reliable and stable reference clock for applications that require precise timing.
