Serial/Deserializer Chipset FPD-Link III (NS)
National Semiconductor Corporation (NS) announced the industry's first serial/deserializer chipset for high-bandwidth digital content protection (HDCP) for automotive infotainment systems. The FPD-Link III chipset delivers encrypted video and audio content in the car, such as Blu-ray movies with playback resolutions up to 720p, allowing passengers to stay in the home as if they were in a home theater. This article refers to the address: http:// National's FPD-Link III serializer/deserializer chipset consists of the DS90UH925Q serializer and the DS90UH926Q deserializer. Both chips can simultaneously transmit digital video, audio and bi-directional I2C control signals over a twisted pair cable, using interface technology that meets the high bandwidth figures developed by Digital Content Protection (DCP) LLC () The relevant provisions of the Content Protection (HDCP) Interface Protocol. High-bandwidth Digital Content Protection (HDCP) technology is fully supported by major content providers such as Warner Bros., The Walt Disney Company and Sony Pictures Entertainment. Each serializer/deserializer chipset has an on-chip memory built in to store a unique high-bandwidth digital content protection master key to protect video content from theft. National's serial/deserializer encrypts data content and ensures that the entire data identification process complies with HDCP regulations. The FPD-Link III serializer/deserializer itself has the ability to process confidential data, streamlining the circuit design of infotainment systems by handling a large amount of computational work, such as data authentication and encryption, without the need to add expensive auxiliary components such as micro-control. And FPGA chips. The DS90UH925Q serializer converts video, digital I2S audio, and control output signals from the host processor into a serial stream of information that is then transmitted over the car cable to each terminal device in the vehicle. The DS90UH926Q deserializer restores the serial stream to video, audio and control output signals, allowing the central display and rear-seat LCD to display information on the screen. The new serializer/deserializer can simultaneously transmit video data and control signals over a differential twisted pair, allowing video systems to use smaller, lighter interconnects, which reduces cost and further simplifies the system. design. Both of these chips deliver serial 24-bit color video to a range of 10 meters and a wide range of pixel clocks from 5MHz to 85MHz. Therefore, designers of automotive infotainment systems can use this chipset to develop a modular platform for the entire video system portfolio, including video sources and displays, ensuring that the same platform can be used in a variety of different vehicles in the same series, including Luxury cars and even ordinary cars. The serializer and deserializer chipset complies with AEC-Q100 Level 2 (Grade-2) and operates over a temperature range of -40 to 105 degrees Celsius and requires only a 3.3V supply. . Both chips have built-in self-test (BIST) mode for in-plant testing, system startup and diagnostics. The FPD-Link III serializer and deserializers have excellent immunity to electromagnetic interference (EMI), ensuring that the high-speed data transmission links of automotive infotainment systems and driver assistance systems meet the stringent regulations of the automotive industry. National's FPD-Link III series serializer/deserializer is suitable for automotive infotainment systems and driver assistance systems. The DS90UH925Q serializer and DS90UH926Q deserializer are the newest members of the series. Price and availability The DS90UH925Q serializer chip in a 48-pin LLP package and the DS90UH926Q deserializer chip in a 60-pin LLP package are sampling and will be available in volume in the second quarter of 2011.
