Agilex™ 3 devices support HDMI 2.1 up to 12 Gbps.
  • Altera recommends that you maintain an inter-lane skew of ±200 mils.

The following figures show examples of the cut-out size on the Agilex™ 5 carrier board for reference.

  • You can optimize the sizes through 3D simulation; or refer to the connector vendor for recommendations.
  • The design adds ground vias and places a cut-out size identical to the signal pad on Layer 2.
  • Additionally, the manufacturing process removes the solder mask on top of the connector pad.
