LMH0030VS Application Field and Working Principle

The LMH0030VS are a family of serializer/deserializer (SerDes) designed for professional AV applications and for high speed interfaces up to 6.375 Gbps. These devices are designed for applications where high speed data transmission between two systems is needed, such as for HD video, audio and other high speed interfaces. They are capable of transmitting over long distances with minimal jitter, and are available in a range of package sizes and I/O configurations. This article will discuss the application field and working principle of the LMH0030VS family of Serializers and Deserializers.

Application Field of LMH0030VS

The LMH0030VS are designed for a variety of professional AV applications, including infotainment systems, video walls, and data systems. These devices are suitable for applications where high speed serialization is needed, and can be used in a range of serial video formats including SDI, HD-SDI, and DVB-ASI. They are also suitable for other high speed interface applications such as GigE, USB3.0, and SATA. The LMH0030VS family of devices is designed for a variety of markets, including Broadcast and Professional AV, Test and Measurement, Military and Aerospace, and Industrial Automation.

Working Principle of LMH0030VS

The LMH0030VS family of devices is a serializer/deserializer that transfers high speed data between two systems. It uses a differential signaling technique to transmit data, which allows for low power consumption, low electromagnetic interference (EMI), and minimal jitter. The devices feature an input equalizing amplifier, which accepts input data and modifies the signal characteristics to improve the transmission performance and reduce jitter. The devices also feature an internal clock multiplier and phase-locked loops (PLLs), which enable the device to generate a high-speed clock at the output, ensuring reliable data transmission. A digital control interface is also present, which allows for the setting of device functions and operation mode.

The devices operate in two modes – Master Mode, in which the device transmits data to the receiver, and Slave Mode, in which the device receives data from the transmitter. In both modes, the device performs serialization of the data, which involves converting parallel data into a serial bitstream. The devices also feature an output de-emphasis system, which helps to reduce the output jitter, increase the performance of the system, and reduce crosstalk between adjacent channels.

Conclusion

The LMH0030VS family of serializer/deserializer devices are designed for a variety of professional AV applications, and are capable of providing reliable data transmission at high speeds, over long distances. The devices feature an input equalizing amplifier, an internal clock multiplier, and phase-locked loops for generating a high-speed clock, and can operate in either master or slave mode. These devices are suitable for a wide range of applications, and are available in a range of package sizes and I/O configurations.
