Introduction
87973DYILFT is a programmable clock generator, which is specially designed for high-performance clock synchronization applications. This product offers a full, programmable synchronous interface compliant to the IEEE1588 and the G.703, while providing the maximum output frequency of up to 633 MHz. The 87973DYILFT also provides several technological and application level features that offer a unique combination of flexibility and performance.Application Field
The 87973DYILFT is ideal for applications that require highly precise clocking and synchronization, such as in telecommunications and network control. This product offers an excellent solution for High Speed Ethernet (HSE) and Frequency Division Multiplexing (FDM) systems which require advanced timing and synchronization capabilities.Furthermore, the 87973DYILFT is well suited for use in Voice over IP (VoIP) systems, which require synchronous timing accuracy and precise jitter control. In addition, the 87973DYILFT is widely used in real-time audio-video applications, such as in DVD players and televisions, where precise timing and synchronization are essential.Working Principle
The 87973DYILFT works by using three main components – an oscillator, a phase-locked loop (PLL) circuit and a combination of synchronous frequency synthesis circuitry.The oscillator generates a high frequency reference signal, usually an atomic frequency standard, to maintain precise frequency accuracy. This oscillator is then connected to a PLL circuit, which can be used to reduce the frequency of the reference signal by a given amount, thus resulting in a synchronized and accurate frequency output.The Synchronous Frequency Synthesis circuitry then takes the output of the PLL and provides an exact, programmable frequency output. This output is then used to provide the precise timing accuracy and jitter control that is essential for most applications.Conclusion
In conclusion, the 87973DYILFT is a versatile programmable clock generator that is ideal for precision timing and synchronization applications. With its advanced features and capabilities, the 87973DYILFT offers an excellent solution for a wide range of clock synchronization applications.
