PI2EQX5804CNJE

Signal Buffers, Repeaters, Splitters Overview

The PI2EQX5804CNJE is a low-power, PCIe compliant signal ReDriver manufactured by Diodes Incorporated. It supports up to 5.0Gbps data rates for PCIe 2.0 interfaces and provides eight differential CML data I/O channels organized into four lanes. The device operates on a single 1.2V ± 0.05V supply voltage and features programmable equalization, amplification, and de-emphasis via pin strapping or an integrated I2C interface. It includes adjustable receiver equalization, transmitter amplitude control, variable input/output termination, and power-down modes.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the component status as End-of-Life (EOL) through official manufacturer documentation before procurement planning. Confirm that the specific ordering suffix CNJE corresponds to the required packaging and compliance specifications. Ensure compatibility with existing design constraints given the discontinuation status.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for applications requiring PCIe 2.0 signal regeneration at 5.0Gbps. Verify that the system architecture accommodates the 1.2V supply requirement and the 100-contact LBGA package. Evaluate whether pin-strapped or I2C configuration methods align with the board layout and control logic requirements.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI2EQX5804C series of PCIe 2.0 Redrivers. It is designed to extend signal reach across backplanes or distant pathways by compensating for attenuation and inter-symbol interference. The device integrates equalization and emphasis circuits to maintain signal quality in high-speed digital environments.
