PI3EQX7841ZDEX

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX7841ZDEX is a single-port USB 3.0 ReDriver manufactured by Diodes Incorporated, designed to optimize signal integrity for high-speed data transmission. It supports a data rate of 5.0 Gbps and features two 100Ω differential CML I/O pairs. The device operates on a single 3.3V ±10% supply voltage with a typical power consumption of approximately 330mW. It includes programmable equalization, de-emphasis, and output swing controls accessible via an integrated I2C interface or pin configuration. The component is housed in a 20-pin TQFN (4x4mm) package and supports an industrial operating temperature range from -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides programmable receiver equalization, de-emphasis, and output swing adjustment to mitigate inter-symbol interference across various physical mediums.
• Integrates a fully programmable I2C interface for dynamic control of signal conditioning parameters when enabled.
• Features automatic input signal level detection and output squelch functions to manage active channel states based on threshold levels.
• Supports adaptive power management through an auto slumber mode and a low-power standby state activated by the EN# pin.

Signal Buffers, Repeaters, Splitters Applications

• Extending USB 3.0 signal pathways between protocol ASICs and switch fabrics over cables or distant data routes.
• Signal conditioning for external storage devices connected via USB 3.0 interfaces.
• Optimizing signal integrity in platforms requiring reliable high-speed data transmission over copper traces.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ZDEX against official Diodes Incorporated documentation to confirm packaging details such as reel quantity and tape specifications. Ensure that the procurement source provides valid traceability and authenticity certificates. Confirm that the component meets the required RoHS compliance standards for your target market. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit components.
