AT8358Z04-CG3U-A

Specialized Overview

The AT8358Z04-CG3U-A is an Ethernet retimer integrated circuit manufactured by Microchip Technology. It features four independent channels capable of operating at data rates between 1.2 Gbit/s and 3.2 Gbit/s. The device supports multiple serial interface standards, including Serial RapidIO, XAUI, InfiniBand, 10 Gigabit Fibre Channel, CPRI, and OBSAI. Designed for signal integrity restoration in high-speed communication links, it addresses the requirements of networking and telecommunications infrastructure applications where signal degradation over PCB traces or cables necessitates active equalization and re-clocking.

Specialized Feature Summary

• Provides four-channel signal retiming to restore eye diagrams for high-speed serial data streams
• Supports versatile protocol compatibility across Serial RapidIO, XAUI, InfiniBand, and 10G Fibre Channel standards
• Enables integration with base station interfaces such as CPRI and OBSAI for wireless infrastructure

Specialized Applications

• High-performance networking equipment requiring long-reach interconnects
• Wireless base station backhaul and fronthaul systems utilizing CPRI or OBSAI protocols
• Storage area networks and server interconnects employing InfiniBand or Fibre Channel

Specialized Procurement Notes

Verify component authenticity through authorized distribution channels due to the prevalence of counterfeit high-speed ICs. Confirm the specific suffix 'CG3U-A' matches the required package and temperature grade specifications. Review the official datasheet for pinout compatibility and power supply requirements before finalizing procurement orders.

Specialized Selection Notes

Select this component when system design requires active signal regeneration for four independent lanes operating up to 3.2 Gbit/s. Evaluate board stack-up and trace length constraints to determine if retiming is necessary compared to passive solutions. Ensure the host controller supports the specific electrical signaling standards listed in the functional description.
