The on-chip oscillators are configured to operate at a wide range of frequencies with minimal jitter, while the integrated voltage regulator ensures minimal power consumption. Additionally, the device can be switched on/off without entering sleep mode, allowing for reduced power consumption.

The working principle of the PL685-P8-038OC-R clock generator is based on a phase-locked loop (PLL) design. A PLL device is a type of frequency synthesizer that efficiently converts an input signal into one or more output signals with a predetermined frequency. The PLL circuit locks onto the input and maintains a precise clock output frequency.

The basic operation of the PLL involves a phase detector that compares the input and output signals and creates an error signal. The error signal is then fed back to the voltage-controlled oscillator (VCO) through a low-pass filter, which adjusts the oscillator’s frequency until it matches the input signal. The result is a precisely frequency-synthesized output signal.

The PL685-P8-038OC-R also includes an adjustable jitter detection circuit. The jitter detection circuit can detect subtle jitter values in the clock signal, allowing for better system control and performance. Additionally, the device offers a wide range of different clock-out waveform formats and frequency ranges, allowing for flexibility in the overall system configuration.

In conclusion, the PL685-P8-038OC-R is a low-cost, low-power, feature-rich clock generator ideal for use in communications, broadcast and industrial sectors. Its PLL-based design utilizes an adjustable jitter detection circuit and a wide range of clock-out waveform formats, allowing for high accuracy, low jitter, and high integration in the tightest designs.
