The PL902150USY-TR is a highly integrated, low-jitter clock generator that are designed to convert an input clock into two automatically synchronized and low-jitter clocks of desired frequencies. It features a highly integrated VCO, PLL, and clock generator, requires a single 3.3V supply and easily supports a wide range of clock frequencies.

The application fields and working principles of the PL902150USY-TR are applicable within the Clock/Timing category, specifically within the Clock Generators, PLLs, and Frequency Synthesizers classifications. All of these technologies are closely related, so their general requirements are not dissimilar.

Within the Clock Generators classification, the clock generator module acts as the central processing hub for the host system’s core clock, by periodically generating scaled output clocks of the desired frequency. These are derived from a single input clock, which is often an external quartz crystal oscillator. This clock is used as the base to calculate the device rate and output frequencies.

The PL902150USY-TR uses the Phase-Locked Loop (PLL) technology to ensure adaptation of the frequency output oscillator\'s to the oscillator’s input frequency and then locks both output frequency and phase. The VCO (voltage-controlled oscillator) is an electronic oscillator that can produce a range of frequencies within the range of 610 MHz to 1525 MHz (approximated), increasing exponentially with impressed voltage.

The PL902150USY-TR also acts as a frequency synthesiser for clock-driven systems. Frequency synthesizers have the ability to change or manipulate frequency very quickly. This allows for tight control of the signals and is widely used in applications such as RF instrumentation, microwave instrumentation, broadband communications, and commercial and military radios.

The PL902150USY-TR device has the capability to be configured through its I2C interface, allowing customers the ability to custom design and regulate the frequency for a particular application. Through the I2C interface, customers can access and customize key device settings, such as its oscillator, PLL, voltage-controlled oscillator, as well as its output frequency and phase margins. Customers also have the ability to read and write to its onboard memory, to store configuration settings that previously programmed.

The PL902150USY-TR also provides excellent jitter performance on its output clocks, further warrants its categorization within the Clock Generators, PLLs, and Frequency Synthesizers classifications. Furthermore, it offers several features to reduce jitter, including the active cycling of the frequency range, output slew, and the ramping of frequencies.

In conclusion, the PL902150USY-TR is a highly integrated, low-jitter clock generator that is designed to convert an input clock into two automatically synchronized and low-jitter clocks of desired frequencies. It is categorized as a Clock/Timing device, specifically as a Clock Generator, PLL, and Frequency Synthesizer, and use its I2C interface to customize device settings, including output frequency and phase margins, as well as enable excellent jitter performance provision of its signals.
