The DS90UB914QSQE/NOPB is an interface serializer/deserializer (SERDES) device designed to transfer 4 lanes of low voltage differential signaling (LVDS) on a single differential pair. It has applications in a variety of technologies, from audio and video to computer networking. The device is also used to transmit and receive Ethernet frames in high speed networks.

The DS90UB914QSQE/NOPB is available in a QFN-48 package and is versatile enough to work in a wide range of environments, from automotive to industrial. Its robust feature set, including 50Ω single-ended outputs and a wide operating voltage range from 1.8V to 5.5V, allows for easy integration into existing system designs. The device is also low-power and offers maximum power savings of up to 60mW when switching from the default operating mode to a low-power standby mode.

The DS90UB914QSQE/NOPB is an LVDS-based serializer/deserializer offering a high degree of flexibility and operational capability. The device is capable of transmitting and receiving information in 8-bit parallel or 20-bit serial mode. In 8-bit parallel mode, data is transferred on four lines, while in 20-bit serial mode, all four lanes are used to transmit and receive a single 20-bit stream. The device can also be configured to support a wide range of LVDS data rates, from 400Mbps to 6.25Gbps.

In addition, the DS90UB914QSQE/NOPB incorporates input equalization, programmable slew rate control, and level shifting, which are useful for reducing insertion loss, improving data integrity, and ensuring compliance with high-speed standards such as SMPTE 295M and SMPTE 424M. The device also features low jitter (typically less than 0.2UI) as well as fast lock/loss of lock detection and hysteresis.

The DS90UB914QSQE/NOPB operates using a number of components, including a pair of input serializers, a pair of output deserializers, four control lines, and four LVDS I/O lines. The input serializer converts the parallel data into serial 20-bit streams, while the output deserializer converts the serial stream back into 8-bit parallel data. The control lines ensure that data is correctly sent and received, while the four LVDS I/O lines are used to transfer the parallel or serial data over the LVDS link.

The DS90UB914QSQE/NOPB is designed to be used in various applications including video processing, full high-definition (HD) video streaming, computer networking, and high-bandwidth automotive infotainment. The device is also well-suited for applications such as 10Gb Optical Transport Network (OTN) and 100Gb/s Ethernet, both of which require high-speed transmission capability and reliable performance. The device also offers integrated jitter tolerance, which helps ensure data transmission quality in high-speed networks.

The DS90UB914QSQE/NOPB is a high-speed, flexible serializer/deserializer device that is well-suited for a variety of applications. The device offers a wide range of features, including 8-bit parallel and 20-bit serial modes, low-power operation, and level shifting. Its integrated equalization, programmable slew rate control, and fast lock/loss of lock detection capabilities ensure data transmission integrity and reliability. Finally, its low jitter and wide operating voltage range make it ideal for applications such as HD video streaming and computer networking.
