[Ultra-high-speed transmission] Hynetek eMarker series helps USB4 80Gbps new era!

Recently the USB-IF Association has opened up USB4 80Gbps Passive Cables certification, and all certified USB4 40Gbps Passive Cables can be certified through the USB-IF Qualification by Similarity (QbS) Program.

The concept of USB4 80Gbps may not be unfamiliar to many friends. As early as September 1, 2022, the USB-IF Association has released a new generation of USB4 version 2.0 data interface specification announcement on its official website, which supports up to 80Gbps data transfer rate, surpassing the speed of Thunderbolt 4 interface. In October of the same year, the association officially announced the new USB4 V2.0 standard specification, which introduces a new generation of USB interfaces with 80Gbps and a new set of naming system.

The launch of USB4 V2.0 version is undoubtedly a major upgrade of data transfer rate. The leap from 40Gbps to 80Gbps not only implies an exponential increase in data transmission efficiency, but also a severe test of hardware equipment, especially eMarker chip performance. However, it is under such technical challenges that Wisers successfully launched several eMarker series products that can pass the USB4 80Gbps certification, including HUSB332B, HUSB332D, HUSB332E, and so on, with its outstanding R&D strength and product performance, providing users with stable and efficient data transmission solutions.

HUSB332B:Ultra Small Form Factor USB eMarker

The HUSB332B is a USB Type-C eMarker for Cable ID applications. It is compliant with USB Type-C Specification Revision 2.1. It is also compliant to USB Power Delivery 3.1 and USB4™ Specification. Powered from VCONN1 or VCONN2, the HUSB332B can determine to act as SOP’. The built-in OTP can be programmed through CC line or I2C bus so that it will be flexible for in-system programming. There are a set of encryption commands implemented in the HUSB332B which can response to the Host or Device in an encrypted ways. It is helpful for the system to identify each other before entering any mode. The HUSB332B operates over a wide supply range of 2.7 V to 5.75 V. It is available in DFN2×2-6L and WLCSP-6B packages. It is rated over the -40°C to +85°C temperature range.
