It is ideal for high-end performance systems, such as network and telecommunications, aerospace and military systems, medical equipment, communication and control systems and more. AB-557-03-HCHC-F-L-C-T is also suitable for applications in which low power consumption is required. In addition, it has excellent immunity to EMI, making it well suited for use in environments with high electromagnetic interference.

Working Principle of AB-557-03-HCHC-F-L-C-T

AB-557-03-HCHC-F-L-C-T works by taking an external clock source and integrating it with a reference input. The reference input is then processed by a phase locked loop (PLL) circuit. The PLL identifies the fast rate at which the incoming clock signal switches and then generates a new square wave clock signal with a frequency that matches the rate at which the original clock signal switches. This new clock signal can then be used as a stable timing source.

In addition to the reference input, the AB-557-03-HCHC-F-L-C-T also includes an integrated switch, crystal oscillator and PLL. The PLL circuit is used to compare the incoming reference clock to the crystal oscillator. The integrated switch is then used to automatically switch between the reference clock and the crystal oscillator, as required. This ensures accurate timing and very low jitter.

Finally, the AB-557-03-HCHC-F-L-C-T includes spread spectrum options to further reduce jitter and overall power consumption. Spread spectrum is a technique which reduces the peak-to-peak jitter of the output clock waveform by spreading the power spectrum over a wider frequency range. By doing this, it reduces the peak power of the waveform, reducing EMI and allowing for better system performance.
