PI2EQX5904NJE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX5904NJE is a PCIe 2.0 compliant signal ReDriver supporting up to 5.0Gbps data rates across eight differential channels or four lanes. It operates on a single 1.2V ± 0.05V supply with typical power consumption of 660mW and supports an industrial temperature range of -40°C to +85°C. The device features adjustable receiver equalization, transmitter amplitude, de-emphasis, and variable input/output termination. Configuration is managed via pin strapping or I2C interface (100Kbps standard rate). It includes channel loopback, mux/demux modes, electrical idle support, and individual output control within a 100-contact LBGA package.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the component datasheet revision matches the required specifications before procurement. Confirm that the ordering suffix corresponds exactly to the intended packaging and environmental ratings. Ensure the supplier provides traceability documentation consistent with Diodes Incorporated manufacturing standards. Cross-reference the part number against official distributor catalogs to validate authenticity and current production status.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring PCIe 2.0 signal conditioning over long traces or cables. Evaluate the need for adjustable equalization and de-emphasis settings based on the specific PCB material loss characteristics. Consider the I2C versus pin-strapped configuration requirements for your design flexibility. Verify that the 1.2V supply voltage aligns with the target platform's power distribution network.

Signal Buffers, Repeaters, Splitters Part Context

The PI2EQX5904 belongs to Diodes Incorporated's EQX series of high-speed signal repeaters. This family focuses on maintaining signal integrity in high-speed serial interfaces like PCIe. The N suffix typically denotes the specific package variant and lead-free compliance within the product line.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Consult the official Diodes Incorporated compatibility matrix for verified substitute part numbers. Do not assume functional equivalence with other PCIe retimers without verifying pinout and register compatibility.
