Application Field and Working Principle of PL585-P8-038OCClock/Timing - Clock Generators, PLLs, Frequency Synthesizers - PL585­P8­038OC is a programmable clock synthesizer designed to produce multiple clocks with an accuracy of better than 1 ns. It is mainly used in communication and data acquisition systems, computer peripherals, medical instruments, and other timing applications.The PL585-P8-038OC consists of a main clock unit, a timing circuit, an internal buffer clock, and an onboard 8-pin PLL output control signal. The main clock source is a 10-MHz external crystal oscillator, which permits frequency multiplication up to 8x and can produce up to 360MHz. The internal buffer clock divides the frequency, providing a clock source for the timing circuit. The onboard 8-pin PLL can synthesize high-frequency signals for further clock multiplying or dividing.The application of PL585-P8-038OC mainly includes clock synthesis for communication and data acquisition systems, and frequency control for computer peripherals, medical instruments, etc. For example, the PL585-P8-038OC can be used to produce frequency precision of clock signals to provide synchronization between timing and signal controlling of computers, networks, and medical instruments.The output of the PL585-P8-038OC is divided into two parts: one is through the 8-pin PLL, and the other is through the main clock unit connected with timing circuits. The 8-pin PLL mainly produces a signal of 1Hz–13MHz. The main clock combines with a variable resistor and uses the timing circuit output, so the working frequency of the clock signal is no more than 1kHz–36MHz.The PL585-P8-038OC provides five control signals: EN, P,M,R&F, and Q. The EN is the enable signal. When high level, the oscillator works and can draw up to 100mA current; when low level, the oscillator is powered off. The P signal is an 8-pin PLL output control signal. When high level, the PLL mode is enabled, the internal output clock is put in PLL control; when low level, the internal clock is in crystal control mode. The M signal is the frequency-multiplier control signal. The R&F signal is used for frequency adjustment. When high level, it is for frequency multiplication; when low level, it is for frequency division. The Q signal is used for resetting the internal counters which are used for frequency synthesizing process.In summary, PL585-P8-038OC is an advanced programmable clock synthesizer designed to produce multiple accurate clock sources in communication, data acquisition, medical instrument, and other fields. The frequency range of its output signal varies from 1Hz to 360MHz via a 10MHz external crystal oscillator and an 8-pin PLL control. It is used mainly to provide synchronization between timing and signal controlling of computers, networks, and medical instruments.
