PI3EQX5801ZDE

Signal Buffers, Repeaters, Splitters Overview

The PI3EQX5801ZDE is a single-lane PCIe 1.0/2.0 ReDriver manufactured by Diodes Incorporated, designed to optimize signal integrity for high-speed data transmission. It supports data rates of 2.5 Gbps and 5.0 Gbps with two 100Ω differential CML I/O pairs. The device operates on dual power supplies: 3.3V (consuming approximately 330mW) or 1.5V (consuming approximately 150mW). It features programmable equalization, de-emphasis, and output swing controls via an I2C interface or pin configuration. The component functions within an industrial temperature range of -40°C to +85°C and is housed in a 20-pin TQFN package measuring 4x4mm.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports PCIe 1.0 and 2.0 protocols with adjustable receiver equalization to mitigate inter-symbol interference.
• Includes input signal level detection and squelch functionality for each channel to manage active states.
• Offers flexible control options through either a fully programmable I2C interface or direct pin configuration.
• Provides low-power standby mode capability when the enable pin is deactivated.

Signal Buffers, Repeaters, Splitters Applications

• Blade Server systems requiring extended PCIe pathways
• PCIe 2.0 cable extensions
• Signal extension across distant data pathways

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'ZDE' against the manufacturer's official documentation to confirm packaging details and compliance status. Ensure that the required power supply voltage matches the design constraints, as the device supports both 3.3V and 1.5V operation with corresponding power consumption differences. Confirm availability through authorized distributors, as stock levels fluctuate.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for applications requiring signal regeneration over PCIe 1.0 or 2.0 links where physical medium limitations cause signal degradation. Choose based on the need for either I2C programmability or fixed pin-configured settings. Consider the thermal environment, as the device is rated for industrial temperatures up to 85°C. Verify that the system architecture utilizes 100Ω differential CML signaling compatible with the device's I/O specifications.
