0804-5000X51

Overview

The Bel Power Solutions 0804-5000X51 is an industrial temperature-rated Single In-line Package (SIP) module designed for Ethernet over Coax (EoC) applications. Based on the Qualcomm Atheros AR7410/AR1500 chipset, it functions as a MAC/PHY/AFE Powerline Communications transceiver compliant with the HomePlug AV standard. The module supports raw data rates up to 500 Mbps within a frequency band of 7.5 MHz to 68 MHz. It features a MII interface and integrates core components for low-cost embedded system integration. Operating voltage is +3.3V, with an operating temperature range of -40°C to +85°C.

Applications

• Ethernet over Coax (EoC) communication systems
• Embedded Powerline Communications devices
• Industrial networking equipment requiring EoC connectivity

Procurement Notes

Verify that external GPIO pull-up/pull-down resistors are set to 3.3kΩ to ensure correct operation, as this differs from the 10kΩ requirement in previous models like the 0804-5000-25. Confirm that the host system utilizes a MII interface, as this model does not support RGMII. Ensure PCB layout adheres to differential pair routing guidelines for the coupling interface signals to maintain signal integrity at high frequencies.

Selection Notes

Select the 0804-5000X51 when a MII interface is required instead of RGMII. This model is suitable for designs needing backward compatibility with existing 0804-5000-25 hardware while upgrading to newer chipset capabilities. Note that maximum Ethernet data rate is limited to 10/100 Mbps due to the MII interface constraint. Verify that the application environment falls within the specified -40°C to +85°C operating temperature range.

Part Context

The 0804-5000X51 is part of the Bel Powerline Modules family, specifically optimized for Ethernet over Coax applications. It complements the existing range of modules based on the Qualcomm Atheros AR7410/AR1500 chipset. The module is designed as a 'Black Box' solution requiring minimal external components and no external software to create a working PLC modem or transceiver.

Replacement Considerations

The 0804-5000X51 is backward compatible with the 0804-5000-25 module. When replacing the older model, update GPIO strap resistors from 10kΩ to 3.3kΩ and account for the limitation to 10/100 Mbps speeds.
