PI3EQX1204EZHE

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX1204EZHE is a four-channel linear redriver manufactured by Diodes Incorporated, designed for high-speed serial data transmission. It supports data rates up to 12.5 Gbps and operates on a single 3.3 V power supply with a maximum current consumption of 260 mA. The device utilizes CML input and output signaling standards to maintain signal integrity across PCB traces. It is housed in a compact 42-pin TQFN package measuring 9x3.5 mm, suitable for surface-mount assembly. This component functions as a signal buffer and repeater to extend link distances in storage and interface applications.
