Working Principle

The 5P35021NDGI is a combined clock generator and frequency synthesizer. It consists of a quartz crystal oscillator, a multiplication network, and a phase-locked loop (PLL) to generate a stable high-speed clock from an incoming reference clock.The quartz crystal oscillator is used to generate the base frequency. This is then sent to the multiplication network which multiplies the frequency to create the desired output frequency. The PLL is then used to achieve tight frequency locking and maintain a stable output clock.The 5P35021NDGI also has two independent reference inputs which can be used to synchronize the output clock to an external clock source. This allows it to be used in various telecommunications networks.
