Clock/Timing - Clock Buffers, Drivers are commonly used to reduce clock jitter and also to provide buffered output signals that may be used as inputs to multiple integrated circuits (ICs). The PI49FCT807ATS is a differential low-skew flexible distributed clock driver, designed to provide low delay and low skew clock distribution on a variety of systems. The IC provides up to three outputs, which can be used to clock data from multiple ICs simultaneously.

The PI49FCT807ATS has several useful features, including a differential input for improved noise immunity and a wide operating temperature range of -40°C to +100°C. The device also has down-skew outputs for improved performance in clock sensitive systems, as well as programmable skew between output pairs for improved circuit layout. Furthermore, the device includes a failsafe output to ensure reliable operation, as well as an adjustable slew rate to improve system noise immunity.

In its simplest form, the device acts as a buffer, connecting an input clock signal to one or multiple outputs. The input signal is amplified, de-skewed and level shifted to improve signal fidelity before the signal is sent to the output. The device can also be used to transmit the clock signal over long distances, by connecting two or more of the outputs in series. In this configuration, the device acts as a repeater; the signal is amplified and delayed at each unit, allowing the clock signal to travel further with minimal degradation.

The PI49FCT807ATS is also capable of distributing clock signals to several different ICs simultaneously. By using a combination of the three outputs and the corresponding control options, the device can transmit a single clock signal to multiple devices, with minimal skew between them. Each output can be configured separately, allowing for further flexibility.

Furthermore, the PI49FCT807ATS provides adjustable skew between the output pairs. This feature can be used to improve the system layout; by adjusting the phase of the output signals, the traces connecting the devices can be arranged in an optimal way. This also reduces crosstalk between the traces, which can further improve the system performance.

In summary, the PI49FCT807ATS is a useful low-skew clock driver, capable of buffering and distributing a single clock signal to multiple output devices. The device also provides several useful features, such as adjustable output skew and a failsafe output, allowing for improved system layout and operation.
