Controllers Procurement Notes

Verify the specific suffix 'AQM-T' against official MaxLinear documentation to confirm package type and temperature grade alignment. Ensure that the required supply voltage levels match the 1.07V to 1.13V specification provided in the datasheet. Confirm that the application environment stays within the -40°C to 85°C operational limits before finalizing procurement decisions.

Controllers Selection Notes

Select this part when a compact solution combining switching logic and physical layer transceivers is required. The inclusion of dual PHYs reduces external component count compared to separate switch and PHY designs. Consider the SGMII+ interface if high-speed uplink bandwidth is necessary for the target network architecture.
