MAX9290：3.12Gbps GMSL Deserializers for Coax or STP Input and MIPI CSI-2 Output

Deserializers Enable Use of Coax Cables, Reducing Weight and Cost of Cabling in Automotive Infotainment

The MAX9288/MAX9290 gigabit multimedia serial link (GMSL) deserializers receive data from a GMSL serializer over 50Ω coax or 100Ω shielded twisted-pair (STP) cable and output deserialized data on the CSI-2 outputs. The MAX9290 has HDCP content protection but otherwise is the same as the MAX9288. The deserializers pair with any GMSL serializer capable of coax output. When programmed for STP input, they are backward compatible with any GMSL serializer. 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 (MAX9290). Two GPIO ports are included, allowing display power-up and switching of the backlight, among other uses. A continuously sampled GPI input supports touch-screen controller interrupt requests in display applications. For use with longer cables, the deserializers have a programmable cable equalizer. The serial input meets ISO 10605 and IEC 61000-4-2 ESD standards. The GMSL supply is 3.0V to 3.6V, the MIPI CSI-2 supply is 1.7V to 1.9V, and the I/O supply is 1.7V to 3.6V. The devices are available in lead(Pb)-free, 48-pin, 7mm x 7mm TQFN and QFND packages with exposed pad and 0.5mm lead pitch.
