USB continues to be the answer to connectivity and charging for PCs, Consumer Electronics, Display and Mobile architectures. It is a fast, bidirectional, low-cost, dynamically attachable interface that is consistent with the requirements of the PC platforms of today and tomorrow.

What is E-marker and Why USB cables need it?

According to research data from the cable industry, the shipment of equipment carrying the Type-C interface is expected to reach 3 billion units by 2024. There are 80% laptops and desktop computers adopting type-c port, and there are 70% smartphones and tablets also using type-c interface.

.An E-Marker (electronic marker) is a chip that is used in the latest USB connector iteration, USB Type-C, to communicate between power source and power sink devices. The chip is used to communicate with connected devices to ensure safe data and power delivery to and from the source and sink. The E-Marker provides the cable characteristics including the cable length, the maximum supported current and voltage, the type of USB signal, the vendor and product ID, any alternate mode support, and much more. An E-Marker is required on all USB Type-C cables that support 5 amps and/or exceed 60 watts of power carrying capability. USB Type-C cables that are expected to have data transfer rates above 480 Mbps, or High-speed USB 2.0, are also required to have an E-Marker chip embedded in the connectors of the cables. Applications that exceed 480 Mbps fall in the USB 3.1 realm, meaning any USB 3.1 cable is going to, with very minimal exceptions, be required, by the USB-IF community, to include an E-Marker in the Type-C cable.
