Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers
The SI5356A-B02647-GM is a clock generator IC, a member of the Si5355 family. It is supplied as a 26-pin LGA package, available in both commercial and automotive rated versions. As a clock generator IC, it is used to generate high-quality reference clocks from a single low-cost external crystal.
The SI5356A-B02647-GM has become an important component for several types of systems. Examples include but are not limited to servers, base stations, point-of-sale networks, routers, switches and basic input/output systems. It is useful in applications where low jitter, fast lock times and flexibility are required. When considering cost, the SI5356A-B02647-GM is not only affordable, but also reliable and robust.
The SI5356A-B02647-GM is a versatile clock generator and can generate up to four outputs. Each output has separate programmable multipliers, dividers and octal PLLs. This permits it to generate clock frequencies from various input frequencies and reference clocks.
The SI5356A-B02647-GM is also capable of generating complex frequency plans with minimal external components. This makes it suitable for systems that require tight integration between components. The clock generator is also used to provide jitter cleaning and error correction, allowing for higher quality output signals.
The working principle of SI5356A-B02647-GM is based on the oscillator and PLL architectures. The oscillator is a phase-locked loop (PLL) which phase locks the oscillator frequency to a reference clock, usually a crystal. The oscillator is then used to generate one or more output frequencies from the reference frequency.
The PLL contains a loop filter, a phase detector and a voltage controlled oscillator (VCO). The loop filter is a low-pass filter with adjustable parameters that are used to control the response of the VCO. The phase detector is used to detect the phase difference between the reference signal and the output signal. When the phase difference is detected, the voltage control oscillator is adjusted to maintain the desired phase lock.
The SI5356A-B02647-GM is a highly integrated device with several advantages such as fast lock time, low jitter, low power consumption and integrated DSP processors. It is designed for the most demanding applications and is capable of providing a very high performance clock. It is thus an ideal choice for any application that requires a reliable clock source with flexibility and high performance.
