The SI5350C-B02224-GT is a high-performance clock generator designed to reduce the complexity of system clock and timing designs. While the device offers a number of features and benefits, two features – an integrated PLL and an integrated LDOs — are especially notable.

The device integrates a low noise PLL and a high-performance, wide-power range integrated linear regulator (LDO), making clock and timing applications easier to design. The integrated PLL lets users select different clock frequencies, as well as generate multiple clocks with very low clock jitter. Meanwhile, the integrated LDO allows for very low power consumption and reduced system complexity. This combination of features allows for efficient, robust and low-power designs.

Application Field

The SI5350C-B02224-GT can be used in multiple application fields, such as networking, storage, industrial, automotive, and control/parameter tuning. For example, in networking, it can be used to generate high-stability reference clock signals for Ethernet networks, for example, for SONET/SDH/PDH transport frames, as well as T1/E1 voice line interfaces. In the storage field, it can be used to provide high-precision jitter-free clocking to disk drives, while its low jitter clock signal ensures reliable operation at the interface level. In automotive applications, it can provide improved temperature stability and accuracy at lower power and cost by replacing crystals with VCOs.

Working Principle

At the heart of the SI5350C-B02224-GT is an ultra-low jitter Programmable Phase-Locked Loop (PLL). The PLL inputs a fixed reference clock and synthesizes multiple output clocks at frequencies that can be adjusted by programming. The integrated LDO is used to adjust the output voltage to the optimal operating voltage required by the PLL. The PLL generates multiple clock outputs with very low jitter, making the device ideal for applications where stability, accuracy, and low noise ± 10ppm are required.

The programmability of the SI5350C-B02224-GT provides flexibility and easy customization of its output frequencies, as well as enabling easy component integration. The device can generate up to sixteen output clocks, which can be individually programmed. The output frequency is directly programmable via a pull-down menu, allowing different frequencies to be selected quickly and easily. The outputs can also be phase shifted, allowing better synchronization between different components.

Conclusion

The SI5350C-B02224-GT is a high-performance, low-power clock generator designed to reduce complexity and improve robustness of system clock and timing designs, while offering a wide range of features and benefits. With its integrated PLL and LDO, it can be used in a wide range of applications, from networking to storage, industrial, automotive, and control/parameter tuning. The programmability and the ability to adjust its output frequencies and phase shift them make it a very versatile device that can be used for a variety of applications.
