DS90UB901QSQ/NOPB

Serialization and deserialization are essential steps for data transmission. The goal of data serialization is to convert data types into a byte stream; and the goal of deserialization is to convert the incoming byte stream back into the original data type. DS90UB901QSQ/NOPB is a dual-channel, low-power LVDS serializer, deserializer (SerDes) device, which enables the peripherals to communicate with the host efficiently and accurately.

DS90UB901QSQ/NOPB Features

The DS90UB901QSQ/NOPB is a high-speed, low-power LVDS SerDes. It includes two independent serial data lanes, and each lane has a transmit and a receive channel. This device supports a data rate up to 1.6 Gbps per channel, and the total data rate for both channels can reach 3.2 Gbps. With its low-power operation, the DS90UB901QSQ/NOPB consumes only 125 mW at typical operating condition.

The DS90UB901QSQ/NOPB features a Three-State output enable control and wide supply operation voltage ranges from 3.135 V to 3.465 V. It can provide up to 200 mA of drive current for each output and is guaranteed to run at temperatures up to +125°C when nominally supplied at 3.3 V.

DS90UB901QSQ/NOPB Application Field

The DS90UB901QSQ/NOPB SerDes provides an ideal solution for a variety of video, display, imaging and communication applications. It can be used in high-speed point-to-point data communications systems, such as high-definitionvideo systems, streaming media systems, digital cameras, radio and satellite communication systems, etc. With its wide operating temperature range and superior power efficiency, this device is perfect for space-constrained product designs.

In addition, the DS90UB901QSQ/NOPB is suitable for applications requiring long-distance transmission of high-speed signals. It can easily handle frequencies up to 2.8 Gbps and transfer balanced data over a wide range of distances, while consuming low power and reducing the need for shielding. Its differential receiver thresholds and output voltage swings are adjustable, making it easy to match with a wide variety of loads and line impedance.

DS90UB901QSQ/NOPB Working Principle

The main function of the DS90UB901QSQ/NOPB is to serialize and deserialize the data stream. On the transmit side, the device takes parallel data from the input source, serializes the data and transmits it. On the receive side, the device deserializes the incoming data and re-formats it into a parallel 8-bit data stream for the destination. It also features an integrated auto-equalization circuit on both transmit and receive paths, which helps to ensure accurate data transmission over long distances. The auto-equalization circuit keeps the transmitter and receiver in full synchronization and compensates for data rate variation and transmission line loss.

The DS90UB901QSQ/NOPB also includes a wide range of protection features to ensure reliable data communication. These features include a fail-safe design, power-on reset, power-down functionality, thermal-overload detection and open/active loop detection. In addition, the device also includes an integrated error detector to detect and report errors, which can then be used to reset the device or to generate an error flag.

The DS90UB901QSQ/NOPB offers a high-speed, low-power SerDes solution for a variety of data communication applications. With its wide operating temperature range, excellent power efficiency, reliable operation and protection features, this device is perfect for embedded systems in demanding environments.
