Interface - Signal Buffers, Repeaters, Splitters commonly employ the PI2EQX4401DZFEX in order to achieve their functions. This device is a single 10-to-10 differential channel capacitor array designed for clock and data line buffering/repeating. The PI2EQX4401DZFEX can operate with a wide voltage range (1.2V to 3.6V VCC) and pushes out up to 12pf without any added board-level capacitance.

Application Field

The PI2EQX4401DZFEX is widely used in various electrical applications that require its particular capabilities. One common application lies in increasing the trace length of a clock or data line, or a line with long transitions. It’s also suitable for driven lines with high speed bursts or edge rates. It also has a wide range of applications in multi-drop LANs, MIL-1553 aviation networks, high-speed point to point networks, and high-speed audio networks.

Working Principle

The PI2EQX4401DZFEX works by providing low impedance paths for both clock and data signals. This device utilizes a capacitor array to provide buffering/repeating for clock and data lines of various widths and lengths. This device allows for different voltages to be applied to the differential pair in order to support additional levels of data transmission. When used in a capacitive mode, which is the default setting, the device can double the trace length on a clock or data line. If used in a resistive mode the device allows for up to four times the trace length.

This device also contains several built-in protection features such as thermal shutdown and over current protection in order to ensure a secure and uninterrupted operation. In addition, it allows for different voltages to be applied to the differential pair and is extremely resistant to ESD, making it ideal for applications that require noise immunity while transmitting and receiving data.

Overall, the PI2EQX4401DZFEX is a superior device for applications that require a reliable buffering/repeating and data transmission mechanism, such as those found in MIL-1553 aviation networks, high-speed point to point networks, and high-speed audio networks.
