Clock/Timing - Application Specific

The SI5338C-B03028-GMR is an application-specific clock device. This clock is tailored for meeting the requirements of a wide range of industrial applications, including automation and robotics.

Overview

The SI5338C-B03028-GMR is a programmable clock generator designed for applications that need precise and stable clock signals. It can be configured to generate precise clocks in a variety of required frequencies and has an low-power consumption, making it ideal for use in industrial systems where power is at a premium. It can also be used to provide redundancy, where the clock signal fails, it can switch to a backup clock without straining the power supply or causing the system to fail.

The SI 5338C-B03028-GMR is capable of providing up to 8 independent high-precision clock outputs in up to seven different frequency ranges with a maximum frequency of 6.500 GHz. The clock generator can be programmed and can generate signals with resolution up to 50 ps (25 ps for some models). The digital frequency dividers enable the user to obtain the necessary frequency for any system application, providing not only a clock with a higher accuracy and stability than off-the-shelf clock oscillators but also customization with frequency, rise and fall times, drive level of the output signal and more.

Working Principle

The SI5338C-B03028-GMR works by using a voltage-controlled oscillator (VCO) to convert an input signal into a higher frequency. This clock generator uses a circuit element called a phase-locked loop (PLL) to precisely tune and control the VCO frequency and use it to generate the required output clock signals. The PLL is, in turn, locked to an input reference frequency. The output clock signals are generated by digitally dividing the VCO output frequency and the controlled frequency can be programmed through an external control line.

Referring to the block diagram of clock generator system, the main components of the system are output buffer, clock synthesizer, PLL and VCO. The clock synthesizer combines the PID controller and digital frequency dividers to provide an accurate output clock. The PLL feeds the VCO which generates the output frequency. Finally, the output buffer amplifier provides isolation, level shifting and slew rate control to ensure a clean clock signal is available for use in the system.

Applications

The SI5338C-B03028-GMR is well suited for use in industrial applications, due to its low power consumption, wide range of frequencies and ability to generate precise clocks in a variety of frequency ranges. It can be used in a variety of applications, ranging from robotic and automation applications to time and frequency transmissions. It can also be used in precision instruments, telecommunications and networking systems.
