PL680-39QC-R

Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The PL680-39QC-R is a programmable clock generator and PLL integrated circuit (IC). This device is capable of generating high-frequency clocks, and it can also be used to synthesize different frequency signals. It can be used as a clock generator to provide a stable and accurate clock signal, as a PLL to produce an output clock frequency, or as a frequency synthesizer to generate frequency up to 600 MHz. The PL680-39QC-R is often used in the industrial, medical, military, and aerospace markets.

Applications

The PL680-39QC-R can be used in a wide range of applications, including instrumentation, industrial, communications, and automotive. In instrumentation it can be used for high-precision timing, syncing, and frequency reference. It can also be used for automated test equipment and broadcasting, as well as for RF frequency generation and for synthesizing other frequencies. In industrial it can be used for controlling industrial processes, production line sequencing, and in robotics. In the communications field it is used for clock and data recovery, network timing, and frequency synthesis.

The PL680-39QC-R is also used in the medical field for digital medical imaging and ultrasound imaging, as well as in military and aerospace applications. It is used for missile guidance systems and synchronizing digital systems, and can be used in frequencies up to 600 MHz.

Working Principle

The PL680-39QC-R operates on 3 inputs - the reference signal, a control signal, and a feedback signal. The reference signal is an input signal that the IC uses to generate the output clock. It is usually a signal provided by an external clock or oscillator. The control signal is used to select whether the IC operates in a Reference Mode, or a Synthesis Mode. In Reference Mode, the input reference signal is used directly as an output clock, while in Synthesis Mode, the IC uses an algorithm to generate the frequency of the output clock.

In either mode, the IC can be locked to a feedback signal, which is usually provided by the output clock signal itself. This allows for very precise clock generation and frequency synthesis. The PL680-39QC-R can also be used as a PLL (phase-locked loop), where the IC uses both the reference signal and the feedback signal to produce a frequency that is phase-locked to the reference signal.

Conclusion

The PL680-39QC-R is an integrated circuit designed for generating and synthesizing clocks and frequencies. It is widely used in industrial, medical, military, and aerospace applications for precise timing, frequency reference, and frequency synthesis. It has 3 inputs - reference signal, control signal, and feedback signal - and can operate in both Reference Mode and Synthesis Mode, with the ability to lock to a feedback signal.
