SI5351A-B05863-GM

SI5351A-B05863-GM is an advanced clock generator module intended for use in high stability clock systems. It is a highly integrated, low-phase-noise device capable of synthesizing multiple simultaneous clock signals over a wide range of output frequencies. The SI5351A-B05863-GM is based on the same basic architecture as its predecessor, the SI5351A, but provides increased integration of features and improved performance.

Application Field

SI5351A-B05863-GM is typically used in applications that require high performance, wide range clock generation. It can be used to generate stable clock signals for high-end computing applications, telecommunications systems, data acquisition systems, system monitoring applications, and medical and test & measurement systems. The SI5351A-B05863-GM is also well-suited for clock signal distribution in multi-chip systems.

Working Principle

The SI5351A-B05863-GM uses a synthesis technique to generate multiple output frequencies from a 30MHz reference frequency. This reference frequency is typically generated by an external oscillator or by an on-board Voltage-Controlled Oscillator (VCO). The VCO frequencies are then multiplied or divided by the frequency synthesizer, and the resulting frequencies are divided further by several frequency dividers to generate the final output frequencies. The SI5351A-B05863-GM can generate up to eight output frequencies by setting the VCO frequency and the divider ratios appropriately. It also offers an integrated phase-locked loop (PLL) architecture, allowing the user to program multiple output frequencies from a single reference frequency.

The SI5351A-B05863-GM also features selectable internal or external reference sources and selectable harmonic suppression through the use of spread spectrum mode. In addition, it features various jitter control features such as frequency jitter attenuation, spread spectrum mode, and spread spectrum gain control. The SI5351A-B05863-GM also provides adjustable parameters for clock & PLL settings, such as frequency range, anti-backlash delay, noise shaping, output buffering, charge pump current, and pre-emphasis.

Conclusion

The SI5351A-B05863-GM is a highly integrated, low-phase-noise clock generator capable of generating multiple simultaneous output frequencies from a single reference frequency. It is ideal for applications that require high accuracy and performance. The SI5351A-B05863-GM provides an integrated PLL architecture and various features such as frequency jitter attenuation, spread spectrum mode, and selectable internal or external reference sources. As the industry demand for clock signals continues to grow, the SI5351A-B05863-GM is well-suited to meet the needs of today’s high-performance applications.
