PI3EQX7502MZDE

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX7502MZDE is a low-power, high-performance 5.0 Gbps signal ReDriver designed for the USB 3.0 protocol by Diodes Incorporated. It features two 100Ω differential CML data I/Os and operates on a single 3.3V supply voltage. The device provides programmable equalization, de-emphasis, and input threshold controls to optimize performance over various physical mediums by reducing inter-symbol interference. It supports an industrial temperature range from -40°C to 85°C and includes automatic receiver detection with adaptive power management capabilities.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides adjustable receiver equalization and pin-configured output emphasis control to mitigate inter-symbol interference across diverse physical mediums.
• Integrates input signal level detection and squelch functions for each channel, automatically driving outputs to common mode voltage when signals fall below active thresholds.
• Supports automatic receiver detection with digital enable/disable, transitioning between active operation, slumber mode, and unplug modes based on load presence and inactivity timers.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Consult official substitution guides for compatible alternatives within the same product family or equivalent functional replacements from other manufacturers. Verify pin compatibility and electrical parameters before implementation.

Signal Buffers, Repeaters, Splitters FAQ

How does the PI3EQX7502MZDE handle inactive channels?

When the corresponding channel’s signal detector is idle for longer than 7.3ms, the device moves to Unplug Mode if no load is detected, or returns to Low Power Mode (Slumber Mode) due to inactivity.

What is the function of the RXD-EN pin?

Pulling the RXD-EN pin high activates the automatic receiver detection loop, allowing the device to monitor for connected loads and manage power states accordingly.

Does the device support independent channel operation?

Yes, each channel operates fully independently, with its own input signal level detection determining whether the output is active based on the applied signal level.
