Maxim’s new LVDS serializer/deserializer (SerDes) gigabit multimedia serial link (GMSL) chipset provides A/V content protection for automotive infotainment and rear-seat entertainment applications.
The MAX9263/MAX9265 serializers and MAX9264 deserializer chipset feature high-bandwidth digital content protection (HDCP) and forms a secure, bidirectional digital-video link (HDCP-GMSL) for transmission of digital video and audio over a single DC-balanced twisted-pair or differential line. The chipset manages all HDCP protocol transactions, supports touch-screen communications, and eliminates the CAN/LIN bus for diagnostics.
Maxim's proprietary differential, full-duplex control channel also enables bidirectional communication with the display module for touch-screen applications. Programmable spread-spectrum modulation reduces EMI, making it easier to pass automotive compliance tests. Other protective features include isolation between the serializer and deserializer through AC coupling. Integrated hot-swap capability increases fault tolerance and allows "on-the-fly" frequency programming. Line-fault detection and integrated self-test features check for link integrity at system power-up.
The MAX9263/MAX9265 operate from a 1.8V core supply, and the MAX9264 operates from a 3.3V supply. These devices feature a separate input supply for interfacing to 1.8V to 3.3V logic levels. The MAX9265 serializer features an LVDS system interface; the MAX9263/MAX9264 have parallel interfaces.
The MAX9263/MAX9264 are packaged in a 10mm x 10mm, 64-pin TQFP, while the MAX9265 comes in a 7mm x 7mm, 48-pin TQFP. These devices are specified over the -40°C to +105°C temperature range. Prices start at $5.55 for MAX9263/MAX9264 and at $6.81 for the MAX9265 (1000-up, FOB USA). Device data sheets, evaluation kits, and samples are available under NDA, according to the company.
