AC-coupled clock generation and multiplexing technology have been developed and improved to improve high-performance system capability. With the increasing number of applications requiring an accurate clock or timing source, the PL123S-09OC-R has emerged as an effective solution.

The PL123S-09OC-R is a clock generator, phase-locked loop (PLL), frequency synthesizer, and multiplexer operating from an input frequency of up to 600 MHz. It is designed to enable crystal-oscillator-based designs to meet the performance needs of a wide range of clock and timing applications. The PL123S-09OC-R is able to achieve fast switching, low jitter, and reliable operation over a wide temperature range.

Application Field: The PL123S-09OC-R is primarily used in applications with stringent timing and clock requirements. These include networking, communication devices, storage devices, gaming machines, memory controllers, industrial controllers, and CPUs. The PL123S-09OC-R can also find use in embedded systems and portable devices.

Working Principle: The PL123S-09OC-R consists of a multiplexer and a PLL circuit. The multiplexer stage uses a predefined ratio to calculate and divide the input frequency to create multiple low-jitter clock outputs. These outputs can be used for various functions depending on the application. The PLL circuit then controls the frequency and phase of the clock outputs, enabling fast switching and reliable operation.

The PLL circuit consists of a phase detector, a loop filter, and a voltage-controlled oscillator (VCO). The phase detector compares the phase of the incoming signal to the phase of an internal reference clock, and generates an output signal that is proportional to the phase difference. This output signal is then low-pass filtered and sent to the VCO, which is used to generate the output clock signal. The phase detector and loop filter components are what enables the clock outputs to operate at the desired frequency and phase.

The PL123S-09OC-R also includes a frequency synthesizer, which is used to generate different frequencies from a single input. This feature allows the user to generate multiple clock outputs from a single input, thereby reducing the complexity and cost of the overall design. The frequency synthesizer works by modulating the frequency of the input signal with a predefined ratio, in order to generate multiple output frequency ranges.

The multiplexer of the PL123S-09OC-R is also an important component, as it allows multiple clocks to be switched on and off quickly and reliably. The multiplexer operates by taking an input signal and dividing it into multiple low-jitter clock outputs. This enables the user to easily switch between multiple clock sources, thus providing a more flexible and cost-effective solution.

In conclusion, the PL123S-09OC-R is a highly capable and reliable clock generator, PLL, frequency synthesizer, and multiplexer. It is able to effectively meet the stringent timing requirements of many applications, and is suitable for use in applications ranging from embedded systems to high-end systems. It provides an effective solution for providing low-jitter clocks and enables users to switch between multiple clock sources quickly and easily.
