The PL602031UMG is a frequency synthesizer which utilises a Phase Lock Loop (PLL) system to generate and control frequency outputs. As the name suggests, the unit is capable of providing wide applicable frequencies ranging from 0.5MHz to 4GHz which can be set and controlled via external connections. It is therefore used by engineers and researchers across a variety of fields; radio-frequency engineering, communications, television broadcasting and other telecommunications applications.

The system comprises of several components including a voltage controlled oscillator (VCO), an internal clock generator, a prescaler and multiple controllable dividers. It is also capable of providing timeslot interval compensation, eliminating the need for external compensation. The multiple controllable dividers allow for frequency accuracy within parts per million (ppm) range.

Working Principle

The frequency generation process starts in the voltage-controlled oscillator (VCO) where it is stabilised by two internally generated reference signals. A phase-frequency detector (PFD) is then used in order to determine if the VCO outputs are synchronised to the externally supplied control signal. This control signal is usually controlled by a clock generator, prescaler and multiple dividers.

When the external signal is \'out-of-phase\' with the VCO output, the PFD will output phase difference which is translated into a voltage representing phase and frequency error. This voltage error is then applied to the VCO via the phase-locked loop (PLL) loop in order to adjust the VCO frequency to the same frequency as the control signal. This voltage correction is repeated until the VCO output and the control signal frequencies are matched.

Once the VCO is stabilised, the output signal is passed through the prescaler and multiple dividers before it is sent to the output. The effect of these components is to reduce the VCO output frequency to the desired output frequency. The frequency accuracy of this output signal is within a few parts per million (ppm) range.

Application Fields

The PL602031UMG is suitable for use in a variety of clock/timing applications. It is used in radio-frequency engineering, communications, television broadcasting and other telecommunications applications. It is also used in industry and research as an accurate frequency source for testing and monitoring purposes. Its wide frequency range and low jitter makes it ideal for stable data transmission between devices.

The unit’s unique phase locked loop system allows users to easily set a desirable frequency and offers immunity to phase noise and phase errors caused by ambient noise. The unit is also capable of providing timeslot interval compensation, eliminating the need for external compensation.

Overall, the PL602031UMG is a highly accurate and low noise frequency generator that is ideal for a wide range of applications. Its wide operating frequency range and high quality construction ensures that it can handle the harshest of conditions and the most demanding of tasks. It is therefore the perfect choice for professionals who need accurate, low noise and high performance clock solutions.
