The DS90CR285-86ATQEVM is one such board, offering engineers a complete kit for evaluating a wide variety of different semiconductor functions, from serializers to deserializers. In this article, we provide an overview of the DS90CR285-86ATQEVM evaluation board, its application field, and its working principle.

Overview of the DS90CR285-86ATQEVM Evaluation Board

The DS90CR285-86ATQEVM evaluation board is a complete kit that allows engineers to evaluate Texas Instruments\' DS90CR285-86A serializer and deserializer (SerDes) devices. It comes with a power supply, debugger, LEDs and GUI for easy system configuration. The board is designed to support two 8-bit parallel buses, an I2C bus, a GPIO interface, and six I/O channels. The evaluation board also features a 50-ohm differential output for testing and debugging, as well as a training mode that can be changed from the assessment phase to the operation phase.

Application Field of the DS90CR285-86ATQEVM Evaluation Board

The DS90CR285-86ATQEVM evaluation board can be used in a variety of applications. As a SerDes device, it is ideal for long-distance high-speed communication applications. The device supports a wide range of data rates that can be used in applications such as consumer electronics, telecom, aviation, automotive, and many more. The device also features a high-performance 8/10-bit transmitter with programmable output power. Additionally, the device offers a programmable de-emphasis capability and has an impressive low ISO jitter.

Working Principle of the DS90CR285-86ATQEVM Evaluation Board

The DS90CR285-86ATQEVM evaluation board operates on the same principles as most SerDes devices. The board consists of two components: the transmitter and the receiver. The transmitter is responsible for producing a differential signal, which is then transmitted over a long-distance link. The receiver is responsible for receiving the signal and reconstructing the transmitted packet. The evaluation board also contains a serial peripheral interface (SPI) for programming the output power, de-emphasis, and other settings.

The board can support data rates ranging from 1 Gbps to 10 Gbps. The board also features adjustable output power from −6 dBm to +3 dBm. In addition, the DS90CR285-86ATQEVM evaluation board supports adjustable de-emphasis settings, with settings ranging from 0 to 6 dB. The evaluation board also has a wide input voltage range, allowing it to operate from both 3.3 V and 5 V power supplies.

Conclusion

The DS90CR285-86ATQEVM evaluation board is an invaluable tool for engineers working to create innovative solutions using SerDes devices. The board can be used in a wide variety of applications, from consumer electronics to telecom and aviation. It features a wide range of data rates, adjustable output power, and adjustable de-emphasis settings. The evaluation board also contains a debug interface, SPI, and an integrated power supply. In summary, the DS90CR285-86ATQEVM is an ideal choice for engineers looking for a reliable and powerful evaluation board.
