3. General PCB Design Considerations

This section provides general PCB layout routing recommendations for Agilex™ 5 VPBGA and MBGA devices. The recommendations include details for different interfaces, as high-speed transceiver area and General-Purpose I/O (GPIO) including EMIF routing.

A type-III PCB board uses standard PTH vias and backdrill technology to balance cost and performance. Each component in a high-speed channel can impact the overall system performance. These components are the device packages, PCB traces, PCB vias, connectors, cables, and landing pads of integrated circuit pins, connector pins, and alternating current (AC) coupling capacitor pins.
