Clock/Timing - Clock Buffers, DriversThe PI49FCT805ATSE is a multi-purpose device developed and designed by Pericom Semiconductor Corporation to provide a wide range of applications and functions, including clock buffers, drivers, phase-locked loops (PLLs), and asymmetric delay lines (DLs). It is ideal for telecommunications, computing, consumer electronics, and automotive applications. Its advanced features make it well suited for advanced consumer electronics, such as high-definition televisions, set-top boxes, and computer monitors. Additionally, its small form factor minimizes the footprint of the device. The PI49FCT805ATSE features an integrated voltage regulator module (VRM) that simplifies signal routing while its frequency range of 5 KHz to 250 MHz makes it suitable for a variety of applications. The device provides a low power consumption rating in multiple power supply levels. It also features adjustable output drive levels, programmable reference delay, and integrated voltage regulation capability.The PI49FCT805ATSE operates using a differential architecture, allowing it to accommodate driver applications such as PCIe, Fibre Channel, 10/100/1000 Ethernet, infrared, and radio links. The device provides a wide range of output drive levels and offset pulses for enhanced system reliability and performance. The device also incorporates a horizontal PLL architecture that helps increase system reliability. Furthermore, the device supports output skew of ± 0.5 ns, which helps ensure low signal jitter and precise clock timing. The PI49FCT805ATSE is designed to support a number of different functions and applications, including clock distribution, frequency synthesis, clock buffer, and driver applications. The device can provide differential signal splitting for increased system performance, or offer output clock enables for power saving capabilities. The integrated differential architecture delivers low jitter, precise timing, and signal integrity. The device can also be programmed to drive multiple outputs simultaneously and reduces signal noise levels.The PI49FCT805ATSE works by using a PLL to synthesize a frequency that drives signals on external pins. It is able to synthesize an exact frequency based on a reference input signal - the main clock signal. The PLL\'s main clock outputs are then buffered and then sent to their respective designations - either a differential, single ended, or multiple output signals. This allows the device to generate accurate timing signals for clock distribution, buffering, and driving. Delay lines are also employed by the PI49FCT805ATSE to generate multiple output signals with precise timing delays. Its adjustable delay lines are used to create precise timing delays, and multiple output chips can be configured for higher data rates and wider reaches. The device also features an adjustable reference delay capability, which provides the system with better control and superior noise immunity. Additionally, the device offers adjustable output drive levels and adjustable output skew for improved noise immunity.In conclusion, the PI49FCT805ATSE from Pericom Semiconductor Corporation is an excellent choice for a wide variety of clock buffer, driver, and phase-locked loop (PLL) applications. Its adjustable delay feature, output drive levels, and integrated voltage regulator make it ideal for consumer, telecommunications, and computing applications. Furthermore, its low jitter and precise clock timing features provide improved system performance and higher signal integrity.
