PL902167USY-TR belongs to the clock/timing family such as clock generators, PLLs, or frequency synthesizers. It is used in a variety of areas such as consumer electronics and communication products, providing a stable and reliable source of clock signal with minimal system jitter. The chip uses a patented high-performance fractional-N technology combined with a low jitter digital phase-locked loop (DPLL) to produce a highly accurate clock frequency output from the reference clock input.

PL902167USY-TR features a configurable reference frequency range from 10 to 400MHz and achieves a low phase noise of -130dBc/Hz when the reference frequency is set higher than 50MHz, making it suitable for a variety of applications. In addition, the chip can generate clock signals with frequencies up to 6GHz with a frequency stability of ±25ppm, so it is suitable for high-end RF products and designs. The chip also supports a wide range of input formats, offering flexible system performance.

PL902167USY-TR comes with a number of practical features that make it ideal for various clock applications. One of the most important features is its configurable loop bandwidth, which allows designers to tune the system to optimize its jitter, noise, and stability performance. It also features an injection lock, which effectively reduces the device’s power consumption in most applications. With its built-in voltage controlled oscillator (VCO), the chip offers a wide range of output frequency adjustment, as well as an automatic calibration function.

The working principle of the PL902167USY-TR is relatively simple. The DPLL consists of a phase detector, a VCO, and a loop filter. The reference signal from an external clock source is input to the DPLL through the phase detector. The phase detector compares the reference frequency with the output of the VCO, and uses the difference to control the VCO. The output of the VCO passes through the loop filter, which removes unwanted frequency components, Returning the filtered output to the phase detector. In this way, the DPLL is able to keep the output frequency in sync with the reference frequency.

The PL902167USY-TR chip is highly versatile and suitable for many clock applications such as network timing, telecom sync and satellite synchronization, and radio frequency communications. The chip offers low power consumption and a high degree of jitter, noise and stability performance, making it a reliable and cost-effective clock solution for a variety of applications.
