Clock/Timing - Clock Buffers, Drivers are electronic circuitry that distributes, buffers, and sometimes drives the input clock signal to achieve a similar level of performance with respect to signal quality, at all of the points to which the signal is sent, as at its point of origin.

PI49FCT3807ASEX is one of these Clock/Timing – Clock Buffers, Drivers. It is a 3.3V complementary output Differential Buffered Clock Driver with extended input/output interface. In addition to a low output-skew between the LVPECL outputs, delay control is integrated at the output enable pin. This design also features an input monitor which allows the output clock to be synchronized to an external system clock.

The application field of the PI49FCT3807ASEX could include telecommunications and data communications, computers and peripherals, hard disk drives, video graphics, instrumentation, automotive and consumer applications.

The working principle of the PI49FCT3807ASEX lies in its ability to reduce the cross-talk between the outputs of the drivers, provide minimal jitter on the output, and reduce the noise on each output. It has low jitter features, low input-to-output delay, optimal loading, and Adaptive Swing Output (ASO) to cater to applications that require world-leading jitter performance.

It includes on-chip isolation diodes for grounding noise protection for LVPECL outputs, and adaptive output peak-to-peak drive capability with 45Ω differential impedance over the full operating temperature range. Moreover, it utilizes an internal charge pump circuit to supply an extra 10V of internal supply voltage, which provides a wide common mode range of VDD −2.2V to + 7.3V. It also helps to reduce the power consumption of the entire signal path.

PI49FCT3807ASEX comes with a fanout buffer which allows up to eleven copies of the signal to be distributed simultaneously and still maintain a signal quality comparable to that of the signal at its point of origin. It also features an asynchronous enable/disable facility that allows the outputs of the device to be quickly switched on or off and provides reduced power states.

Moreover, the PI49FCT3807ASEX includes an adjustable delay control and one-cycle setup/hold parameter so that the output clock can be adjusted with respect to the input clock. This feature allows the output clock to be synchronized to an external system clock.

Overall, the PI49FCT3807ASEX is an effective and reliable Clock/Timing – Clock Buffers, Drivers that are the perfect solution for applications requiring high-speed clock signal distribution. Not only can it reduce cross-talk to a minimum, but its wide range of features such as low jitter, adjustable delay control, and on-chip isolation diodes make it an ideal choice for many applications.
