CDC2586PAHRG4 is a Clock Generator family which provides high-performance, low jitter, low-power features in an integrated way. This generator has three identical frequency outputs, with adjustable voltage control to provide precise clock synchronization. The generator also features a Watch Signal Output in order to detect any errors during transmission of the internal clock signal. It can be used to generate a precise synchronization signal while using a precise internal oscillator.

The main purpose of the CDC2586PAHRG4 clock generator is to provide a synchronized timing source. The generator features an internal master oscillator (MOSC), which operates at around 50 MHz, to generate a stable and precise clock signal. This signal is then passed through a phase-locked loop (PLL) that adjusts it to the desired frequency. The output of the PLL can then be used as a precise system clock, providing stable and accurate timing for many applications.

The PLL chip on the CDC2586PAHRG4 is designed for low-power operation, with a power consumption of less than 30 mW. The chip also features Zero Resolution mode, a low-power sleep mode which can provide an additional 12-second accuracy to the generator. This mode is beneficial for applications that require precise and accurate timing, such as audio and video broadcasting.

The CDC2586PAHRG4 also features two outputs, A and B, which can be used to generate different frequencies. Output A is the main output, while output B is used to generate second or third order frequency outputs as needed. Output A is also capable of providing synchronous output signals to other devices, thus allowing turn-on/off synchronization and cascading.

The main application areas of the CDC2586PAHRG4 clock generator are in the communication, industrial, automotive and aerospace industries. It is widely used in communication networks such as IEEE 802.3 Ethernet, Asynchronous Transfer Mode (ATM), and Synchronous Optical Network (SONET). The generator is also used in factory automation for synchronizing machines, in industrial control systems for timing and sequencing, and in GPS-based automotive applications.

The working principle behind the CDC2586PAHRG4 clock generator lies in its ability to generate a precise frequency signal without the need for an external clock source. The generator uses an internal MOSC (Master Oscillator) as the source and a PLL (Phase-Locked Loop) as the frequency synthesizer to obtain the desired frequencies. The MOSC is connected to a comparator, which is wired to an inverting buffer input and an amplifier. The output of the buffer is connected to the PLL, which multiplies and adjusts the frequency to the desired level. Finally, the signal is sent to a frequency divider to generate the output frequencies.

In conclusion, the CDC2586PAHRG4 clock generator is a highly efficient and low-power system, providing precise and synchronized clocks for many applications. It uses an internal oscillator and a PLL to generate precision frequencies and has two independent outputs, A and B, which can be used to generate different frequencies. Its application areas include communication, industry automation, military, automotive, aerospace and much more. Therefore, the CDC2586PAHRG4 clock generator is an invaluable tool for many industries.
