LMH0051SQE/NOPB

The LMH0051SQE/NOPB is a monolithic, high speed, low power serializer that is used to convert parallel digital video communications into parallel digital video signals. The unit is particularly suited for applications where simultaneous data transmission is necessary. It provides frame synchronization, data multiplexing, forward transmission, and backward transmission.

Application Field

The main application of the LMH0051SQE/NOPB serializer is in digital video communications, both in household applications and for mobile and broadcast applications. It is used for both progressive and interlaced mode distributed video transmission. Common applications include High Definition TV (HDTV) and standard definition (SD) digital video transmission.

The serializer supports a variety of data rates, from 155 Mbps to 3.4 Gbps, for use with different types of video formats. These include ITU-R 601, SMPTE-274, SMPTE-296, SMPTE-424, SMPTE 292, and numerous other formats. The converter can also be used to multiplex a variety of data sources, such as audio, video, and data, into a single data stream.

Working Principle

The LMH0051SQE/NOPB serializer works by receiving a digital video signal and converting it into a serial data stream. The unit then converts the serial data stream into a parallel video data stream, divided into 8-bit words. Each word is assigned a unique serial number and transmitted over a dedicated line. The serial number is used to track the position of each word in the data stream.

The data is then passed through a deserializer, which stores the data in its assigned location in the parallel video stream. The deserializer uses the serial numbers to determine the position of the words in the stream and assembles them into the correct video data format. The deserialized video signal can then be used to produce the image.

Conclusion

The LMH0051SQE/NOPB serializer is a versatile converter, designed for applications involving digital video transmission. Its unique design allows for both progressive and interlaced mode distributed video transmission, allowing for the transmission of both audio and video signals. The serializer is capable of handling data rates from 155 Mbps to 3.4 Gbps, and is suitable for a variety of video formats.
