The DS90UB949TRGCRQ1 is an integrated serializer/deserializer (serdes) circuit designed to convert stereo video/audio information into a single channel serial data stream, and vice versa. The deserializer converts the single channel serial data stream back into the original individual stereo video/audio formats. Engineers from many industries rely on this device for purposes ranging from digital video broadcast (DVB) systems to high-speed data transmission.In a nutshell, this circuit takes the baseband data from digital video and audio devices such as digital TV receivers and home theater systems, and combines them into a single bit stream. This bit stream is then converted back into the original stereo format for output. This approach is more efficient because the image and sound data can be transmitted over a single channel as opposed to multiple channels.In more detail, the DS90UB949TRGCRQ1 consists of two components: a serializer and a deserializer. The serializer converts the video/audio data into a single serial data stream by combining the individual components. This serial stream is then converted into a wide-bandwidth serial data stream by the deserializer. The result is 10-bit super video resolution and 14-bit audio resolution.In order to achieve this conversion, the DS90UB949TRGCRQ1 must be operated within certain operating conditions. The parameters such as input voltage, input impedance, and bandwidth requirements are set in such a way that the output waveform is “clean”, meaning free from distortion or noise. The circuit also incorporates numerous analog noise-canceling techniques, thereby eliminating the need for additional filtering.In addition to providing serialization/deserialization capabilities, the DS90UB949TRGCRQ1 can also be used as a jitter attenuator. This is possible because the device features an internal jitter attenuation mechanism which allows for reduced jitter in the final output. The device also features an integrated bypass mode, which allows for an alternative output source to be used in case of an emergency.The applications for the DS90UB949TRGCRQ1 vary depending on the customer’s requirements. It is perfect for use in professional audio/video systems, automotive infotainment applications, home theaters, and industrial systems that require high-speed data transmission. It is also ideal for broadcast systems and data networks.In conclusion, the DS90UB949TRGCRQ1 is an integrated serdes circuit that provides an efficient and reliable way to convert digital video/audio data into a single serial data stream, and vice versa. This device is simple to integrate into existing systems, and its various features make it perfect for a wide range of applications.
