MAX9249GCM/V+TGG5

Serializers and deserializers are components used to transfer data between two entities, such as the processor and the memory, or a transmitter and a receiver. There are many types of serializers and deserializers, such as SATA, USB, PCIe and so on. The MAX9249GCM/V+TGG5 is a serializer and deserializer specifically designed for audio and video applications. In this article, we will discuss the application field and working principle of this device.

Application Field

The MAX9249GCM/V+TGG5 is an integrated encoding IC which mainly supports video, audio and graphics data. It integrates .serializer and deserializer, video and audio format conversion, ADC and DAC. As a result, the device is mainly applied for video and audio applications, such as digital broadcast and multimedia terminals. It supports a wide range of video formats such as 1080p60Hz, 2K/120Hz, 4K/30Hz, etc. It also supports HD audio formats such as Dolby Digital Plus and Dolby TrueHD, as well as Dolby Atmos. In addition, it provides high reliability due to its built-in self-test functions, error correction and PLL-based jitter reduction.}

Working Principle

The MAX9249GCM/V+TGG5 device consists of serializers, deserializers, video format conversion, audio format conversion, ADC, PLLs and self-test functions on one chip. It works as follows:

• The serializers convert the incoming digital video and audio data into a serial bitstream.
• The deserializers convert the serial bitstream back into the digital video and audio data.
• The video format conversion circuit converts the incoming digital video data into the desired output format, such as 1080p60Hz, 2K/120Hz, 4K/30Hz, etc.
• The audio format conversion circuit converts the incoming digital audio data into the desired output format, such as Dolby Digital Plus and Dolby TrueHD, as well as Dolby Atmos.
• The ADC converts the analog video and audio signals into digital video and audio signals.
• The jitter reduction circuit, based on PLLs, reduces the jitter in the system.
• The built-in self-test functions ensure that the device is running properly.

The MAX9249GCM/V+TGG5 device is designed with an eye towards cost savings. As such, it reduces the need for additional circuitry and components, resulting in a lower overall system cost.

Conclusion

In conclusion, the MAX9249GCM/V+TGG5 is a serializer and deserializer specifically designed for audio and video applications. It integrates a serializer and deserializer, video and audio format conversion, ADC and DAC, as well as jitter reduction and self-test functions. The device provides a cost-effective solution for digital broadcast and multimedia terminals.
