Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers – M2021-11-622.0800 is a high precision frequency synthesizer that uses pulse width modulation (PWM) technique for clock generation.

The PWM technique provides the required precision and accuracy of the generated clock. The output frequency is determined by the duty cycle of the PWM. The frequencies of the generated clock can be set to any desired value within range by suitable selection of duty cycle.

The device is configured by setting the duty cycle with pulse durations of 1.5 and 2.5 micro seconds. The default value of the duty cycle is 50%. By changing the duty cycle, the frequency of the clock signal can be varied according to the set ratio.

The frequency step is determined by the crystal frequency divided by the total count. The number of counter can be increased when higher frequency stability is required. The frequency can still be changed by the duty cycle.

The device does not require any external components, such as capacitors and resistors, for its operation. All the components needed for its operation are already built into the device itself.

The device features an on/off switch, an indicator LED to indicate the presence of clock signal, a programmable frequency select switch and an output port for the clock signal. The device provides 24-bit resolution and is ideal for generating high frequency clock signals with very low jitter.

The device is suitable for use in a wide range of applications, such as clocks for embedded systems, embedded microcontrollers, radios, digital signal processors, etc. It can also be used for time and frequency synchronization tasks, precise frequency measurement and time-keeping.

The device has a built-in power supply, and also supports external power supply. It also supports external control, thanks to its built-in programmable frequency select switch. The device can be programmed to provide different frequencies, from 100 Hz to 20 MHz. The output clock signal is clean and free of noise.

The device is capable of operating at temperatures ranging from 0 to 70 degrees Celsius, and can withstand a maximum of 80V. The power consumption is low, and does not require active cooling. The output signal is provided in the CMOS form, and can be easily interfaced with other circuits. The device is built according to the international standards, and is RoHS compliant.

The device is a high precision, reliable, and cost-effective solution for generating clock signals in embedded systems. It is suitable for various applications such as datacom, telecom, audio, video and instrumentation. The device is designed to provide accurate time keeping and precise frequency signals.
