3. Scope of System Design Guidelines

Intel® recommends that you consider the prerequisites listed below:
  1. Understand all HDMI 2.1 CTS requirements per HDMI.Org and strive to meet both Protocol and Electrical Specifications.
  2. Refer to all existing platform level requirements (eg: Development Kit Guides, Platform Design Guides (PDG), Application Notes (AN) and all available resources).

You can use an existing development kit together with this system design guide to enable a HDMI 2.1 capable system. If you require an accelerated Time to Market (TTM) product roadmap, you have the option to adopt the daughtercard design recommendations and Intel development kit. If you choose to create a proprietary design, you can use the guidelines to assist you develop a design that meets compliance more easily, saving time and costs.

The reference design implemented on the daughtercard has passed HDMI 2.1 CTS testsuite. Electrical attributes have been characterized by Electrical Validation. The settings are optimized per correlation to development kit setup.

Electrostatic Discharge (ESD) is needed to protect the silicon from being damaged due to ESD events from a typical usage model. Intel® Arria® 10 devices that use the application of redrivers/retimers do not require additional ESD clamp circuitry. However, you must assess the ESD requirements per your design needs.

The recommendations are results from the HDMI 2.1 daughtercard development iterations, but are also applicable to other board topologies. Thus, in the subsequent chapters, the document uses the PCB panel to describe the design in general.
