NJU3712D is an interface device belonging to the Serializers and Deserializers (SERDES) category. This device is designed to provide a reliable transmission connection between high-speed source and target systems, such as in data communication, network communication and industrial control systems. Specifically, NJU3712D is a compact, single-chip, non-blocking, 3-2-1-level multiplexer with built-in channel and frame synchronization capability. It is built with low-power CMOS technology, which not only provides high-performance properties but also reduces power consumption.

NJU3712D Application Field

The NJU3712D interface device is an ideal solution for high-bandwidth communication and network applications where low-latency point-to-point data transmission and effective parallel connection of two or more devices are required. Its multiplexing and synchronization capabilities make it well suited for transferring data in real-time environments, like audio and video streaming. Additionally, the NJU3712D is suitable for applications where Control bits are needed to maintain synchronization, such as antenna actuator tracing in the medical imaging systems.

NJU3712D Working Principle

The NJU3712D is a combination of a multiplexer and a frame synchronization module. It supports both unidirectional and bidirectional data transfers and is capable of achieving a stable communication link between the source and target systems. On the hardware level, the multiplexer consists of three stages. The first stage is the phase-locked loop (PLL), which is responsible for providing accurate clock signals to the other parts of the circuit. The next stage is the frame synchronization circuit, which is responsible for constructing timing frames that evenly divide the incoming data stream into discrete blocks. Finally, the multiplexer section combines the incoming data bits from different sources into one or two single data streams.

In operation, NJU3712D accepts incoming data from both the source and target systems. First, it checks for a valid clock signal from the source system. If a valid clock signal is detected, the multiplexer will start sending proper sync pulses to ensure that the data frames are correctly constructed. Then, NJU3712D will read the incoming data from both source and target systems and multiplex them into one or two output data streams. Finally, the result is sent to the target system.

In addition, the NJU3712D interface device also provides a Control bit stream to maintain the proper data flow and communication link. This Control bit is used to indicate the start and end of the data frame as well as the state of the communication link. This offers a more robust and reliable connection between the source and target systems.

Conclusion

NJU3712D is a powerful interface device that belongs to the Serializers and Deserializers (SERDES) category. It is most suitable for data and network communications, as well as network control applications. It combines a multiplexer, frame synchronization module and Control bit stream to provide an efficient, low-latency transmission connection between the source and target systems.
