The DS90UB904QSQE/NOPB is a quad deserializer designed to interface up to four high-speed LVDS signals with data rates up to 1.2 Gbps to one low voltage differential signaling (LVDS) bus. It is designed to meet JEDEC standard signaling levels and tolerate HCSL, LVPECL, LVDS, and CML input levels. It provides a 4:1 multiplexed output that can transfer the four LVDS inputs to a common LVDS output.The DS90UB904QSQE/NOPB belongs to a category of devices called Serializers, Deserializers.

The DS90UB904QSQE/NOPB is ideal for a wide range of applications, including communications and networking, medical imaging, radar systems, test and measurement, and automation systems. It is suitable for high-speed data acquisition, HD imaging systems, and wireless communications.It can also be used to integrate FPGAs, ASICs, and MEMs chipsets with LVDS interfaces in applications such as automotive, military, and industrial.

The DS90UB904QSQE/NOPB can receive up to four high-speed LVDS signals with data rates up to 1.2 Gbps.It deserializes each of these four signals by decoding them into 8-bit data words, and it then multiplexes them into a single LVDS output. The LVDS output can then be used for further downstream processing or transmission. The device also includes configurable output skew and configuration reads for ease of use.It is programmable via an I2C interface and includes programmable input equalization, output levels, data rate, and power-saving modes. There is also an output enable for turning off the device and saving power when it is not in use.

In conclusion, the DS90UB904QSQE/NOPB is an ideal solution for high speed communication systems and applications that require a high bandwidth data transfer. It has a wide range of applications and is programmable through an I2C interface. With its quad deserializer design, it can receive up to four high-speed LVDS signals with data rates up to 1.2 Gbps and multiplex them into a single LVDS output.
