DS90UR904QSQ/NOPB

The DS90UR904QSQ/NOPB is a quad-channel, LVDS-to-LVDS, low-voltage differential signaling (LVDS) serializer/deserializer (SerDes) that supports simultaneous transmission of four low-voltage, high-speed data lanes between chips or across a printed circuit board. It is a SerDes that receives parallel data and serializes it into a high-speed differential signal and then transmits it over a transmission line. In the future, the reverse direction is performed in the same way or inverted data to perform the deserialization.

The DS90UR904QSQ/NOPB includes a serial control port (SCP) for programming some of the Serializer/Deserializer features like output swing, input/output swing, clock speed, master/slave configuration, and multiplexing. Additionally, it has output enable pins that can be used to independently disable specific channels. It is implemented as an integrated circuit (IC) and it is available in a small quad flat package (QFP) with 0.5 mm lead pitches for easy implementation.

Due to its low power, fast transition speed, and excellent signal integrity, this Serializer/Deserializer is suitable for a wide range of applications including automotive, high-end networking, and consumer electronics. In particular, it can be used in DVD players, digital audio/video systems, multi-display applications, military systems, and medical instruments. The device can also be used in other applications where reliable and low-power signal integrity is required.

Application Field and Working Principle

The DS90UR904QSQ/NOPB is primarily used for serializing and deserializing high-speed data. It is ideal for applications where multiple data channels need to be transmitted over a single data link. It functions by accepting parallel data streams and converting them into a differential signal. This differential signal is then transmitted over a transmission line. On the receiving end, the process is reversed and the data is deserialized. The DS90UR904QSQ/NOPB supports speeds up to 500 Mbps per channel and offers low power dissipation, making it an attractive option for applications where power is a concern.

The device enables designers to achieve maximum performance while consuming minimal power. It works by accepting parallel data channels in the form of nibbles or bytes, and it then serializes them into a single bit stream. It supports two different modes of operation: Data Deserializer mode and Data Output Deserializer mode. In the Deserializer mode, it receives a differential signal and converts it into parallel data. In the Output Deserializer mode, it takes in parallel data and outputs a differential signal.

The DS90UR904QSQ/NOPB features a serial control port (SCP) for programming various features and parameters of the device. This port is used to adjust the input/output swing, output swing, clock speed, master/slave configuration, and multiplexing. Additionally, the device includes output enable pins which can be used to independently disable specific channels.

The DS90UR904QSQ/NOPB is a highly integrated and feature-rich serializer/deserializer that is suitable for a wide range of applications. With its low power consumption and excellent signal integrity, it is an ideal solution for automotive, high-end networking, and consumer electronics. It is also an excellent choice for applications in military and medical systems where reliable and low-power performance is required.
