AR8033-AL1A-1

Drivers, Receivers, Transceivers Overview

The AR8033-AL1A-1 is a legacy third-generation Ethernet PHY transceiver manufactured by Qualcomm Atheros. It supports data rates of 10Mbps, 100Mbps, and 1Gbps across three independent channels. The device interfaces with MAC controllers via RGMII or SGMII protocols and features an integrated 1.25GHz SerDes for direct optical module connectivity. It operates on a single 3.3V supply, internally generating required voltages. Electrical specifications include typical operating voltages of 1.1V, 2.62V, and 3.3V. The component is housed in a 48-pin QFN EP package with dimensions of 6mm x 6mm and a height of 0.74mm, suitable for commercial temperature ranges from 0°C to 70°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '1' against official Qualcomm documentation, as standard listings often reference 'R'. Confirm current availability status, as this product line is designated as legacy and not recommended for new designs. Ensure compatibility with existing PCB layouts and verify RoHS compliance details for the specific revision before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component only for maintenance of existing designs utilizing Qualcomm Atheros PHYs. Evaluate alternative modern solutions for new projects due to its legacy status. Consider pinout compatibility and software driver support when migrating from previous generations. Verify that the 48-pin QFN package fits within the mechanical constraints of the target enclosure.

Drivers, Receivers, Transceivers Part Context

The AR8033 series represents Qualcomm Atheros' fourth-generation Ethernet PHY technology. It succeeded earlier models like the AR8031 and AR8032. The chip is designed for high-density networking applications requiring multiple ports. It integrates physical layer signaling with media access control interfacing capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

Official substitutes are not explicitly listed in public documentation. Consult Qualcomm distributors for equivalent legacy parts. New designs should consider modern alternatives recommended by Qualcomm for third-party platforms.
