Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The 5P49V5901B602NLGI8 is a timing and clock generation device, designed for use as a Reference Clock Generator, PLL, or Frequency Synthesizer. It is capable of generating multiple clock frequencies for use in communications systems, primarily for use in Frequency Division Multiplexing and Time Division Multiplexing systems (FDM & TDM). This device is capable of providing a highly stable reference clock, plus multiple programmable reference clock speeds and frequencies, which may be used for data rate synchronization across multiple channels in communications systems.

Application Field

The 5P49V5901B602NLGI8 timing and clock generation device can be used in a variety of different applications, including in telecommunications systems and in industrial automation. The device is capable of providing a highly stable reference clock, plus multiple programmable reference clock speeds and frequencies, which may be used for data rate synchronization across multiple channels in communications systems. It is also capable of providing short-term synchronizing pulses for fiber data transmission, IPTV/voice/data service synchronization, high-speed data sampling, and clock timing issues in industrial control systems.

Working Principle

The 5P49V5901B602NLGI8 provides a highly stable Reference Clock, in addition to a variety of programmableReference Clock speeds and frequencies. As an example, in a TDM system, the 5P49V5901B602NLGI8may be used to provide a Reference Clock of 9kHz as the TDM clock signal, as well as multipleprogrammable speeds and frequencies do not require precise synchronization, a precision of121 parts per million (PPM) may be obtained by using the 5P49V5901B602NLGI8 with two differentgenerators. The two generators, a Reference Clock Generator (RCG) and a Cyclical Generator(CG), work in conjunction with each other to provide the precise synchronization.

The RCG is used to generate the primary Reference Clock signal, which is then used to control the frequency of the resultant TDM clock signal. The CG works in an analog fashion, to modulate the RCG frequency, thus allowing for precise control of the resultant TDM clock frequency. The interaction between the two generators ensures that the resultant TDM clock signal is precise and stable. This allows the 5P49V5901B602NLGI8 to act as a precision Control Platform for communications systems.
