The PL602-21TC is a pulse width modulator (PWM) static frequency synthesizer. It is most commonly used as a clock generator, frequency synthesizer, or phase-locked loop (PLL). These applications all involve the synthesis of a frequency of a certain accuracy that is adjustable and can be synthesized by varying small changes in the frequency and/or duty cycle.

At the heart of the PL602-21TC is a oscillator with an output frequency range of 6 to 35MHz. This oscillator is coupled to a programmable divider which is used to synthesize a new frequency from the output of the oscillator with a selectable accuracy of 1 Hz to 10 kHz. This synthesized frequency is then output from the PL602-21TC via a selectable 5V, 10V or 15V TTL compatible output.

The PL602-21TC also incorporates a phase-locked loop (PLL). A PLL is an electronic circuit which is used to generate a synthesized signal that is locked in frequency and phase to the input reference signal. The PLL in the PL602-21TC is a voltage-controlled oscillator (VCO) with a frequency range of 4 to 30MHz. It is driven by a 4-bit signal from the programmable divider, which is used to set the frequency of the VCO. The VCO output is then phase-compared with the input reference signal and the resulting error voltage is used to control the frequency of the VCO.

The PL602-21TC is a versatile and highly accurate frequency synthesizer capable of synthesizing output frequencies from 4 to 30MHz. It can be used in a wide range of applications such as clock and frequency synthesis, PLLs and frequency modulation. The PL602-21TC is ideal for applications requiring high-accuracy and flexibility such as data processors, radio transmitters, security systems and telecom applications.
