Programmable oscillators are devices that enable digital signals to be generated by frequencies from a few kHz to gigahertz and even low frequency audio signals. CPPLC4-HT56T is a digital-on-demand type programmable oscillator, which is based on the new and enhanced digital-on-demand modeling technology. Its main application field is for radio frequency front and intermediate devices, systems, embedded programs and other occasions where there are long-term stability and small drift frequency requirements.

CPPLC4-HT56T device can realize the on-demand mode program and output frequency sweep. It adopts the integrated fixed frequency type oscillator, which can output up to 50MHz of high-precision frequency stability. The device contains the innovative control algorithm (i.e. PID algorithm) and frequency calibration algorithm. Besides, it has the built-in temperature compensation circuit, which can improve temperature range stabilities.

The working principle of CPPLC4-HT56T is simple. First of all, an external reference oscillator is connected to the device to set a reference frequency. After that, an external programming line can be used to select a reference frequency and the output frequency of the device is matched to the reference frequency. Then, an internal phase-locked loop (PLL) circuit can be used to track the programmed frequency. Finally, the device\'s output is calibrated and the frequency is corresponding with the reference frequency.

CPPLC4-HT56T\'s digital-on-demand model is suitable for nearly all types of radio frequency demand, from low frequency audio signals to semi-microwaves or even gigahertz signals.Due to the integrated fixed frequency type oscillator, CPPLC4-HT56T can output long-term stability and small drift frequency. Moreover, its innovative PID algorithm, frequency calibration algorithm and built-in temperature compensation circuit can further improve the stability and accuracy of frequency.
