DS90UB904QSQX/NOPB is a type of serializers and deserializers, or SERDES, integrated circuit (IC). SERDES devices are used in digital communication systems to convert parallel data streams into serial data streams and vice versa. SERDES devices are often used along with high-speed communication links such as Ethernet, USB, and PCI Express.

The DS90UB904QSQX/NOPB, like most SERDES devices, contains two high-speed serializer and desserializer stages, as well as an integrated phase-locked loop (PLL). The serializer stage encodes parallel data streams into high-speed serial data streams, while the deserializer stage decodes the serial data back into parallel data streams. The PLL ensures that the transmitted and received serial data streams are properly synchronized and the data is reliably transmitted and received. The device is typically used for data rates up to 6.25 Gbps.

The DS90UB904QSQX/NOPB is used primarily to connect multiple devices, such as computers and peripherals, to a common high-speed data link such as PCI Express, Ethernet, or USB. The device supports up to four independent differential channels of serial data, with each channel capable of transmitting and receiving data at up to 6.25 Gbps. The device also supports the USB-C standard, providing up to 5 Gbps of data throughput.

A common application for the DS90UB904QSQX/NOPB is in storage systems, such as solid-state drives (SSDs). The device is used to connect the SSD’s controller to a host computer, for example a laptop or desktop, via the high-speed interface. The SSD controller receives the parallel data from the host computer, serializes it to a high-speed serial data stream, and sends it to the SSD memory. The SSD memory then returns the serial data, which is deserialized back to a parallel data stream, and provided to the controller.

Another application for the DS90UB904QSQX/NOPB is in communication systems. The device is used to connect different processors, like an ARM processor and an Intel processor, to a common high-speed data link, such as Ethernet. The DS90UB904QSQX/NOPB is used to serialize and deserialize the data transmitted and received between the processors. The device is also used to provide protocol translation so that the different processors can communicate and understand each other.

The DS90UB904QSQX/NOPB is a high-performance and reliable device for connecting different devices and enables them to communicate with each other over high-speed serial and parallel buses. Its integrated PLL ensures that data is transmitted and received reliably and in a synchronized manner. The device can be used in a variety of applications, from storage systems to communication systems, and its support for the USB-C standard provides up to 5 Gbps of data throughput.
