The PL130-07QC-R is an advanced clock buffer/driver from Pericom Technology. The clock buffer/driver can operate from 2.375V to 3.465V and supports multiple output frequency settings from 2.5 to 160MHz. It can be used to drive a variety of applications, including frequency division, clock buffering, and clock synchronization and transmission. This article will discuss the application field of the PL130-07QC-R and the working principle behind it.

Application Field

The PL130-07QC-R\'s primary application is as a clock frequency division device. It can be used to accurately divide a chip\'s clock frequency over various bands, such as low-frequency/high-frequency bands and fixed-frequency/variable-frequency bands. This makes it possible to generate multiple signals with different frequency characteristics for a variety of hardware applications. It can also be used for clock buffering, allowing it to divide clock frequencies without conflicts between stages. Finally, it can be used for clock synchronization and transmission. With PL130-07QC-R, communication between central processing units (CPUs) can be synchronized to achieve higher bandwidth and improve system performance.

Working Principle

The PL130-07QC-R uses two integrated circuits (ICs) in one package that operate at different frequencies to divide the clock input frequency. The first IC called the buffer IC operates at a fixed frequency and creates an initial clock signal. This signal is then used as the clock source for the second IC, which can be configured to divide the clock into the desired frequencies.

The buffer IC consists of a low-noise operational amplifier, an oscillator, and a phase-locked loop (PLL). The oscillator creates a sine wave according to the input voltage and is amplified by the operational amplifier. This signal is then fed into the PLL to boost its power and create a low-jitter output. The low-jitter output is then used as the clock input for the divider IC.

The divider IC operates at a variable frequency and can divide the clock into either a fixed or a variable frequency. It consists of a phase-frequency detector, a charge pump, a voltage-controlled oscillator (VCO), and a divider. When a clock input is applied, the phase frequency detector sends a signal to the charge pump, which generates a voltage that varies with the clock frequency. This voltage is then used to control the VCO, which creates an output signal of the desired frequency. This signal is then fed into the divider, which divides the frequency into multiple frequencies that can be used for various applications.

Conclusion

The PL130-07QC-R is a clock buffer/driver from Pericom Technology. It can be used for multiple applications, including clock frequency division, clock buffering, and clock synchronization and transmission. It uses two integrated circuits that operate at different frequencies to divide the clock input frequency, with a buffer IC operating at a fixed frequency and a divider IC operating at a variable frequency. This makes it possible to generate multiple signals with different frequency characteristics, improving system performance.
