84314AYLF Application Field and Working PrincipleClock/Timing - Clock Generators, PLLs, Frequency SynthesizersClock Generator, PLL (Phase-Locked Loop) is a circuit used to generate a particular frequency clock signal. Frequence Synthesis uses a combination of logic signals, analog signals and digital signals to create a signal with a specific frequency. 84314AYLF Clock Generator/PLL/Frequency Synthesizer is used to generate various clock/timing signal in multiple circuit applications.The 84314AYLF Clock Generator/PLL/Frequency Synthesizer is a monolithic IC (Integrated Circuit) frequency synthesizer integrated with both output clock and control logic. It is designed to reduce component count and space requirements. It helps reduce system cost and size by eliminating the need for external logic circuits.Furthermore, the 84314AYLF Clock Generator/PLL/Frequency Synthesizer can be used as a low jitter reference clock generator, modulating PLL, frequency translator, clock recovery circuits, as well as Digital decoding and correction decoding.The 84314AYLF includes three essential components: a clock generator, a PLL and a frequency synthesizer. The clock generator generates a stable low frequency high stability references for the PLL. The clock generator also receives an external resonator or clock input to generate a reference clock to be used by the PLL. The reference clock is then used to generate high-frequency clocks using the PLL. The frequency synthesizer then receives the output of the PLL and synthesizes different frequencyclock signals.The 84314AYLF Clock Generator/PLL/Frequency Synthesizer provides the following functions:• Low jitter reference clock generator – the 84314AYLF uses a fixed frequency reference oscillator to generate a low jitter reference clock.• Modulating PLL - the 84314AYLF can be used as a modulating PLL to adjust the frequency of a reference clock.• Frequency translator – the 84314AYLF can be used to translte one frequency clock to another frequency of clock.• Clock recovery circuits – the 84314AYLF can be used to recover and resynchronize the clock from an incoming data stream. • Digital decoding- the 84314AYLF can be used for decoding and recovery of digital data from incoming data streams.• Correction decoding – the 84314AYLF can be used for correction decoding of digital data from incoming data streams.In addition to the above functions, the 84314AYLF is also capable of generating a number of output clocks with varying frequencies to drive other ICs. These output clocks have a very low jitter, making them suitable for digital circuits. The 84314AYLF is an ideal solution for applications such as Digital Video Broadcasting (DVB), set-topboxes, modems, and wireless communication devices requiring low power and high performance clock generators. It is also suitable for data and mobile communication application, digital decoder application and embedded systems requiring low jitter clock generator solution. The 84314AYLF Clock Generator/PLL/Frequency Synthesizer application includes in the following scenarios:• Base station synchronization – digital transceivers and base station application,• Multi-channel receiver applications – satellite and bus radio receivers,• Recurrent and non-recurrent clock synchronization,• HDSDI/SDI video transmission and reception - broadcast television SDI/HDSDI applications,• Digital video broadcasting applications – satellite, cable and Digital Video Broadcasting (DVB),• Wireless communications – GSM, CDMA, Bluetooth and WiFi standard,• Systems requiring clock synchronization and adjustment.The 84314AYLF uses a variety of techniques to ensure a low jitter clock signal. This includes a frequency division technique and an integer part frequency division interpolation technique. The 84314AYLF utilizes an all digital phase locked loop, which can generate a frequency of 1MHz to 150MHz. The all digital PLL reduces the noise, jitter, and spurious components found in output signals.The 84314AYLF also has adjustable parameters to facilitate programming for the desired output frequency and control. These parameters are preset by the user, and can be adjusted easily. This is done through a 4-bit wide input port, which is used to select the desired clock.In conclusion, the 84314AYLF Clock Generator/PLL/Frequency Synthesizer is a powerful solution for generating stable low jitter clock/timing signals in multiple applications. It provides a comprehensive solution for clock signals, and fits perfectly in circuits that require low jitter clock signals. The 84314AYLF can be used in a variety of applications, including base station synchronization, multi-channel receivers, recurrent and non-recurrent clock synchronization, digital broadcasting, wireless communications, and more. It is the ideal choice for circuits requiring low jitter clock signal generation.
