The SI5338A-B05125-GMR is a high-performance, low-latency clock generator suitable for data security, networking, mobile and consumer audio applications. It is an integrated circuit that can be used to generate multiple frequencies from a fixed reference signal source. The SI5338A-B05125-GMR is ideal for generating a variety of low-skew output clocks for widespread use in applications such as data storage, consumer electronics, communications, and PC clock synchronization. The SI5338A-B05125-GMR can also be used for jitter attenuation and spread-spectrum clocking in applications where size, power and cost are a priority.

SI5338A-B05125-GMR is a clock/timing - application specific integrated circuit (ASIC) suitable for a wide range of applications. It is designed to generate clocks with high accuracy and low ripple at multiple frequencies from a single reference clock. The output clock frequencies are programmable, allowing customers to tailor system performance to their specific clock requirements. It is an integrated programmable high-performance clock generator that is ideal for use in data security, networking, mobile, and consumer audio applications.

The SI5338A-B05125-GMR has built-in features such as spread-spectrum and jitter attenuation capabilities to support low-EMI (electromagnetic interference) designs. It also offers more advanced features such as programmable current limit for output drivers and multi-phase output timing for improved system synchronization. Furthermore, the SI5338A-B05125-GMR offers a PLL (Phase-Locked Loops) and a reference buffer for improved jitter performance. The PLL aboard this IC helps ensure that all outputs maintain a high degree of precision and frequency accuracy across wide temperature range and supply voltage variations.

The working principle of the SI5338A-B05125-GMR is that it first uses an external reference frequency to produce an accurate clock signal, then amplifies the signal and distributes it to the clock outputs. The chip contains a Phase Locked Loop (PLL) to regenerate the reference frequency to accurately control its output frequency. The PLL will “lock” onto the reference frequency, and then use a digitally controlled oscillator (DCO) to generate its output. The oscillator is designed to have a very fast settling time, so that it can switch frequencies multiple times within a single clock cycle. The exact output frequencies can be configured by a digital interface which is provided as a parallel or serial port.

SI5338A-B05125-GMR is ideal for applications requiring multiple high-performance, low-jitter clock synchronization, fast output settling times and low power consumption. It is very easy to use and configure, with a flexible architecture and built-in features to facilitate a wide range of applications. This integrated circuit can be used for many different clock/timing applications, such as data storage, consumer electronics, communications and PC clock synchronization, spread-spectrum and jitter attenuation, and more.
