The 83947AYI-147LF is a clock buffer/driver from Texas Instruments that is used in various electrical and electronic applications. This device is designed to provide a buffered, low phase-noise clock signal to a variety of devices. It is especially used in applications that need to have accurate timing and clock synchronization, such as digital data processing systems.

The 83947AYI-147LF has a single differential HCSL clock input that is then distributed to multiple clock outputs. The device has 8 differential clock outputs and two single-ended clock outputs so that multiple clock signals can be distributed with precise timing and low phase noise. The device supports frequencies from 25MHz to 250MHz, with up to 0.5V differential amplitude.

In order to ensure accurate and reliable performance the 83947AYI-147LF has a number of on-chip features. It has a programmable output delay of up to 4ns to ensure precise synchronization, a programmable skew between outputs to ensure precise timing of clock signals and adder circuitry to reduce the total jitter of the clock signal.

The 83947AYI-147LF has a wide range of applications in electronic and electrical systems. It can be used to distribute a precise clock signal to systems that require accurate timing and clock synchronization, such as digital data processing systems. It can also be used in signal distribution networks to ensure multiple signals are evenly distributed and with low jitter.

The working principle of the 83947AYI-147LF can be explained by looking at its inputs and outputs. When the device receives the clock input, it buffers and amplifies the signal before distributing it to the various outputs. The device will then proceed to detect the signal frequency and amplitude and adjust the output levels accordingly. It also adjusts the output skew and delay to ensure precise synchronization between the outputs. This allows the device to provide an accurate and reliable clock signal to multiple destinations.

In summary, the 83947AYI-147LF is a clock buffer/driver from Texas Instruments that is used in various electronic and electrical applications. It has a single differential HCSL clock input that is then distributed to multiple clock outputs. The device supports frequencies from 25MHz to 250MHz, with up to 0.5V differential amplitude and has a range of on-chip features to ensure precise synchronization and low phase noise. The device can be used to distribute an accurate and reliable clock signal to systems that require precise timing, as well as signal distribution networks.
