A DS90UB933-Q1EVM is an evaluation and demonstration board that consists of a Q1 Ultra Low Power High-speed 1-Port USB Type-C redriver, which is meant to be used by developers and engineers for the development of products with USB Type-C port support. Evaluation and demonstration boards in general offer developers the opportunity to observe and measure the functionality and performance of the product while also enabling them with the freedom to customize and develop as per their demands. The DS90UB933-Q1EVM supports USB Type-C implementations and is part of the Diodes Incorporated family of signal conditioning solutions.

The DS90UB933-Q1EVM comprises of two main features- an upstream static/multilevel redriver and a downstream one-side unidirectional/bidirectional redriver that are both configured via voltage/current; both offer overvoltage protection to combat system transients and offer 16dB or better of equalization in order to extend differential signalling lengths up to 15 meters in order to support the USB Type-C protocols. The XRC Debug Port enables live hardware debugging and gives engineers full control of all the parameters and their effects. The debug port is programmable and can be used to fine-tune system performance.

The DS90UB933-Q1EVM has been designed to address the USB Type-C interface applications and meets the USB Power Delivery Standard, as well as the DisplayPort Alternate Modes Standards. It supports Redriver operation on both USB 2.0 and 3.1 Gen1/2/3 lanes, including SS (SuperSpeed) data rates. It is able to deliver up to 10 Gbps of data bandwidth and can terminate up to 15 meters of cable at high signal rata. Furthermore, the bidirectional redriver can support reverse power up to 15W.

The system can also provide up to 15dB of equalization to compensate for signal losses due to parasitics, vias, and track-length differences. This reduces the effects of signal reflections inside the system and helps maintain signal integrity over extended lengths. The DS90UB933-Q1EVM also offers overvoltage protection to prevent system transients that can potentially occur due to external power sources.

The software needed to control the system is a part of the DS90UB933-Q1EVM package. The user can use the GUI software provided by the vendor in order to easily configure the board, and debug and fine-tune the system’s performance. The software also allows the user to save and store configuration profiles so that they can be used for different products.

The DS90UB933-Q1EVM is an ideal device for those working on the development and implementation of USB Type-C protocols in their products. It is especially useful for those dealing with cables and connectors due to its extended reach of up to 15 meters. It offers developers great flexibility and performance with its overvoltage protection, equalization support, and easy-to-use GUI software, enabling them to optimize their system for best performance. Thus, DS90UB933-Q1EVM is a great choice for engineers and developers looking to quickly and conveniently develop products with USB Type-C ports.
