The PI6C2405A-1HLE is a frequency synthesizer in the Clock/Timing - Clock Generators, PLLs, and Frequency Synthesizers family. It is a highly integrated phase-locked loop circuit used in applications such as broadcasting, monitoring, optical fiber transmission systems, digital broadcast system phones, cellular phones, Internet bases stations and other communication applications which require a low phase noise and high jitter attenuation frequency reference.

The PI6C2405A-1HLE features very low jitter and noise levels, typically less than 0.68 ps RMS for jitter and -90 dBc/Hz for noise at 1 kHz offset, minimizing peripheral electronic devices such as delay line and phase detectors needs in frequency synthesizer application. It is also suitable for 100 MHz-300MHz PLL and reference generator front-end designs. The PI6C2405A-1HLE includes 16-bit prescaler which is suitable for high frequency PLL design.

The PI6C2405A-1HLE working principle allows selection between two reference clock input frequencies, either a 13.5 MHz/2-27MHz or a 27/2-54MHz clock. The Clock Generation module provides two low jitter outputs on divergent frequency families, one at 10MHz and the other at 0.1458375MHz. The Clock Monitor circuit monitors the “divided-by-2” and “divided-by-4” outputs from the Clock Generation module and initiates a reset of the entire PLL circuit if the monitor output is not within a predetermined time interval. The PI6C2405A-1HLE also provides a clock output of 25Mhz or 50MHz. The output of the PLL circuit is also selectable between an integer divided PLL output and a fractional divided PLL output.

The PI6C2405A-1HLE can be used in a wide variety of applications, including personal computers, communication systems, radio receivers, multi-channel audio systems and video systems. It’s main application field is in broadcasting studios which require low phase noise and high jitter attenuation frequency references. In broadcasting, the derived clock signal is required to be highly accurate and stable to improve the performance and reliability of the transmission.

The PI6C2405A-1HLE is also suitable for use in communication applications such as optical fiber transmission systems, digital broadcast system phones, cellular phones and Internet bases stations, where high frequency performance and stability is required.

The PI6C2405A-1HLE is designed to meet the latest standard for low power dissipation for various components that run on high frequency signals. It uses a low-power CMOS design, allowing for significant power savings without sacrificing performance and reliability. The PI6C2405A-1HLE also features low EMI and ESD ratings.

In conclusion, the PI6C2405A-1HLE is an excellent frequency synthesizer in the Clock/Timing - Clock Generators, PLLs, and Frequency Synthesizers family which provides low jitter and noise levels and is suitable for use in applications such as broadcasting, communication systems, radio receivers, multi-channel audio systems and video systems. Its low power design and high stability makes it an ideal choice for various high frequency applications.
