The DS90UH926QSEVB/NOPB board is an evaluation board that is part of a series of evaluation and demonstration boards and kits manufactured by Texas Instruments. It is designed to be used to evaluate the performance and features of the DS90UH926QSEVB/NOPB digital video/graphics display port signal switch. With this evaluation board, users can test the DS90UH926QSEVB/NOPB’s versatility in applications like automotive infotainment systems, broadcasting systems, computer systems, and other applications needing multiple ports of digital video and/or graphics.

The DS90UH926QSEVB/NOPB is based on the quad-channel DS90UH926QSEVB/NOPB that has eight general purpose I/Os and two general purpose inputs. It has two 9-bit single-ended inputs and four high-speed termination devices to allow for flexible design of high-speed interconnects. The evaluation board also includes various features like a series pass transistor, an open-drain driver, isolation diode, and series resistor for high-speed signal types such as LVDS, LVTTL, and RSDS. The board ensures a comfortable test platform with its low-noise characteristics, current capacity, and short turn on delay time of 1.0µs typ.

In terms of working principle, the DS90UH926QSEVB/NOPB switch portfolio features a unique and patented design that supports multiple ports for digital video and/or graphics, allowing for high channel-count solutions in systems that need multiple ports of digital video and/or graphics. It is a configurable 4:1 multiplexer or switch that allows up to four inputs and one output or one input and four outputs to be used simultaneously. The board has an embedded mux logic which can make routing decisions, allowing the user to set the mux ports to any value desired. The board also features a wide frequency range from 1MHz to 170MHz, a high R- and F-termination of 50Ω±10%, and a very low power consumption of 0.7mW typ.

The DS90UH926QSEVB/NOPB is an easy to use evaluation platform with flexible configuration options, that can be used for the evaluation of digital video/graphics display port switches in applications such as automotive infotainment systems, broadcasting systems, computer systems, and industrial control systems. The board is also capable of meeting the highest standards for signal integrity with its low-noise characteristics, current capacity, and short turn-on delay time of 1.0µs typ.
