The MAX9266 gigabit multimedia serial link (GMSL) deserializer features an LVDS system interface and high-bandwidth digital content protection (HDCP) decryption for content protection of DVD and Blu-ray™ video and audio data. The deserializer pairs with any HDCP-GMSL serializer to form a digital serial link for the transmission of control data and HDCP-encrypted video and audio data. GMSL is an interface approved by Digital Content Protection, LLC (DCP).

The deserializer features 3-channel and 4-channel modes. The 3-channel mode outputs three lanes of LVDS data (21 bits), UART control signals, and three audio outputs. The 4-channel mode outputs four lanes of LVDS data (28 bits), UART control signals, three audio outputs, and auxiliary control signals. The three audio outputs are for I²S audio, supporting an 8kHz to 192kHz sampling frequency and a sample depth of 4 to 32 bits. The embedded control channel forms a full-duplex differential 9.6kbps to 1Mbps UART link between the serializer and the deserializer. An electronic control unit (ECU) or microcontroller (µC) can be located on the serializer side of the link (typical for video display), on the deserializer side of the link (typical for image sensing), or on both sides. The control channel enables ECU/µC control of peripherals on the remote side, providing such functions as backlight control, touch-screen input, and HDCP-related operations.

The serial link signaling is AC-coupled current-mode logic (CML) with scrambled 8b/10b coding. For driving longer cables, GMSL serializers have programmable pre/deemphasis, and the deserializer has a programmable channel equalizer. For reduced EMI, the deserializer has programmable spread spectrum on the LVDS and control outputs. The serial link inputs and the LVDS output meet ISO 10605 and IEC 61000-4-2 ESD standards. The deserializer's core supply is 3.3V and the I/O supply is 1.8V to 3.3V. The device is available in a 48-pin TQFP package with an exposed pad and is specified over the -40°C to +105°C automotive temperature range.

Product Detail

The MAX9266 evaluation kit (EV kit) provides a proven design to evaluate the MAX9266 high-bandwidth digital content protection (HDCP) gigabit multimedia serial link (GMSL) deserializer with LVDS system interfrace and spread spectrum and full-duplex control channel. The EV kit also includes Windows XP®-, Windows Vista®-, and Windows® 7-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the MAX9266.

The MAX9266 EV kit comes with a MAX9266GCM/V+ installed.

For complete GMSL evaluation from LVDS inputs, order both the MAX9266 EV kit and its companion board, the MAX9265 EV kit.

For complete GMSL evaluation from CMOS parallel inputs, order both the MAX9266 EV kit and its companion board, the MAX9263 EV kit. For simplicity, this EV kit data sheet uses a MAX9265 EV kit serializer.
