    The MAX9291B/MAX9293B GMSL serializers convert an HDMI input to a gigabit multimedia serial link (GMSL) output for transmission of video, audio, and control signals over 15m or more of 50µ coax or 100µ shielded twisted-pair (STP) cable. The MAX9293B has HDCP content protection, but is otherwise the same as the MAX9291B. The serializers pair with any GMSL deserializer capable of coax input. When programmed for STP output, the serializers are backward compatible with any GMSL deserializer. The output amplitude is programmable 100mV to 500mV single-ended (coax) or 100mV to 400mV differential (STP).

    The audio channel supports L-PCM I²S stereo and up to eight channels of L-PCM in TDM mode. Sample rates of 32kHz to 192kHz are supported with sample depth up to 32 bits.

    The embedded control channel operates at 9.6kbps to 1Mbps in UART-to-UART and UART-to-I²C modes, and up to 1Mbps in I²C-to-I²C mode. Using the control channel, a µC can program serializer, deserializer, and peripheral device registers at any time, independent of video timing and manage HDCP operation (MAX9293B). A GPO output supports touch-screen controller interrupt requests from the remote end of the link. For use with longer cables, the serializers have programmable pre/deemphasis. Programmable spread spectrum is available on the serial output. The serial output meets ISO 10605 and IEC 61000-4-2 ESD standards. The core supply is 1.8V and 3.3V and the I/O supply is 1.7V to 3.6V. The devices are available in lead(Pb)-free, 56-pin, 8mm x 8mm TQFN and SWTQFN packages with exposed pad and 0.5mm lead pitch.

    Product Detail

    The MAX9291B/MAX9293B evaluation kit (EV kit) provides a proven design to evaluate the MAX9291B/MAX9293B HDMI input with high-bandwidth gigabit multimedia serial link (GMSL) output serializer with spread spectrum and full-duplex control channel with the use of a standard FAKRA coaxial cable. The EV kit also includes Windows Vista®- and Windows® 7-compatible software that provides a simple graphical user interface (GUI) for exercising features of the serializers. The EV kit comes with a MAX9291B or MAX9293B IC installed.

    For complete GMSL evaluation using a standard FAKRA coax cable, order the MAX9291B/MAX9293B coax EV kit and a companion deserializer board (MAX9276B/MAX9280B coax EV kit referenced in this document). For testing with STP cable, also order the MAXCOAX2STP-HSD adapter kit. Only one adapter kit is needed per link (connecting the serializer and deserializer boards).

    Applications

    • High-Resolution Automotive Navigation
    • Megapixel Camera Systems
    • Rear-Seat Infotainment
