PI3EQX501BZAEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX501BZAEX is a single-channel USB 3.0 ReDriver manufactured by Diodes Incorporated, operating at data rates up to 5.0 Gbps. It utilizes an 8-pin TDFN (2x2 mm) package and requires a single 3.3V supply voltage. The device features adjustable receiver equalization with selectable settings of 3 dB, 6 dB, or 9 dB, and pin-configurable output de-emphasis control offering 0 dB, -3.5 dB, or -6 dB levels. It incorporates input signal level detection, automatic receiver detect functionality, and adaptive power management including Slumber mode.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides programmable equalization and de-emphasis to optimize signal integrity over various physical mediums.
• Includes low-level input signal detection and output squelch functions for active channel control.
• Features automatic receiver detect loops that manage transitions between active, slumber, and unplug modes.

Signal Buffers, Repeaters, Splitters Applications

• Extending USB 3.0 signals across distant data pathways on user platforms.
• Connecting protocol ASICs to switch fabrics or cables.
• Signal extension in external storage devices and digital cameras.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the component against official datasheets to confirm the specific ZAEX suffix indicates tape and reel packaging. Ensure the ordering information matches the manufacturer's current documentation to avoid discrepancies in quantity per reel or handling specifications.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending high-speed USB 3.0 differential signals requiring low power consumption. Consider its 3.3V operation and 8-pin TDFN footprint for space-constrained designs. Evaluate the need for adjustable equalization and de-emphasis to compensate for specific trace losses.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3EQX501 family of USB 3.0 Redrivers designed by Pericom Semiconductor, now part of Diodes Incorporated. It serves as a signal buffer and repeater specifically optimized for Super Speed USB protocols to maintain signal quality over extended lengths.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Signal Buffers, Repeaters, Splitters FAQ

How does the device handle power management during idle states?

The device enters a low power Slumber mode if the signal detector is idle for longer than 1.3 ms. If idle for longer than 6 ms without load detection, it moves to Device Unplug Mode.

What are the available equalization settings?

The EQ pin allows selection of three equalization levels: 3 dB (Logic Low), 6 dB (Open/Default), and 9 dB (Logic High).

Is the device compatible with Host Mode?

Yes, the PI3EQX501B is explicitly described as Host Mode Capable in its feature list.
