The PL560-38QC is a programmable clock generator that supports inputs from an external reference clock and generates a wide frequency range of output clocks. It is a dual-channel device able to lock and track the phase, rate, and frequency of a master clock and generate two independent, synchronous clock outputs. The feature set of the PL560-38QC provide flexibility to support applications such as high-speed communication, storage systems and digital audio/video.

Features

The PL560-38QC offers a variety of features to support high-performance applications:
• Supports input frequency range of 392 kHz to 860 MHz
• Two synchronous outputs and enables operation up to 3800 MHz
• Integrated PLL/VCO allows user to select desired frequency output
• Integrated loop filter with adjustable bandwidth allows user to tailor start-up time
• Very low jitter performance at 25 to 3800 MHz output range
• FMEA, failure mode and effects analysis compliant

Application Fields

The PL560-38QC can be utilized in a variety of applications. It is used to stabilize clock signals and reduce distortion/noise from incoming signals, in order to ensure proper data transmission and minimal errors. Therefore, the PL560-38QC is frequently found in high-speed communication and storage systems, as well as with digital audio/video applications such as broadcast video.

One key benefit of the PL560-38QC is its ability to lock and track the phase, rate, and frequency of an external reference clock. This feature allows the system to remain in operation even when there is a variance in the reference clock. Additionally, the device is able to generate two independent synchronous clock outputs, which helps to reduce the number of components needed, and therefore, cost and space.

Working Principle

The PL560-38QC works within a frequency range of 392 kHz to 860 MHz. The device can accept a clock signal from an external reference clock through its PLLs, and then it can generate two separate and independent outputs. The generated outputs are typically fractions of the reference clock, which means it can track and lock the frequency, rate and phase of the reference clock.

The PL560-38QC also features an internal loop filter with adjustable bandwidth, which allows the user to adjust the start-up time of the device. The VCO is capable of operating up to 3800 MHz, depending on the input frequency.

Finally, the device incorporates FMEA, failure mode and effects analysis, which enables the user to analyze the system’s functionality. The PL560-38QC has a very low jitter performance, which is essential in applications involving high-speed communication and storage systems.
