The 49FCT3805DQGI8 is a chip produced by Fairchild Semiconductor that is used as a clock buffer and driver. It is used to provide reliable clock signals with minimal jitter, provide adequate noise margins and prevent data corruption. It is specifically designed to provide high speed output and a low propagation delay.

The 49FCT3805DQGI8 is used in a variety of applications, most notably in chip-to-chip communications, high-speed memory and digital signal processing. In communications, it serves to ensure the data sent is accurately received, due to its low propagation delay, providing reliable clock signals to any data that is sent. In digital signal processing, its high speed output is used to reduce the processing time of complex algorithms as well as reduce noise levels. High speed memory applications, such as in high-end networking, require that the chip be able to provide reliable, low propagation delay clock signals in order to meet the data throughput requirements of the application.

The 49FCT3805DQGI8 is a 3.3V device with a maximum clock frequency of 66MHz and a maximum data rate of 133MHz. It has sixteen output buffers, each with a fanout of three, which allows for a maximum of 48 outputs. It is able to source or sink up to 32mA of current and works in both a dedicated clock buffer or a distributed clock application. It also comes with an internal delay line which allows for an adjustable propagation delay of up to 100ns. The delay line can also be used to skew the clock signals to reduce crosstalk and ensure signal integrity.

The working principle of the 49FCT3805DQGI8 is fairly simple. First, the input clock signal is sent to the device through the CLK0 pin. The device then buffers and processes the signal before it is then sent to the output. This ensures that the buffered clock signal has a low propagation delay, minimal jitter and the correct amount of noise margin. The internal delay line can be used to adjust the delay of the clock signal and to ensure that it arrives at its destination in a timely manner.

The 49FCT3805DQGI8 is a versatile chip that is used in a variety of applications to provide reliable, high speed clock signals with minimal jitter. Its low propagation delay, adjustable delay line and 32mA drive capability make it a suitable choice for both chip-to-chip communications and digital signal processing.
