The MAX9276B/MAX9280B 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 LVCMOS outputs.
The MAX9280B has HDCP content protection but otherwise is the same as the MAX9276B. The deserializers pair with any GMSL serializer capable of coax output including the MAX9293 HDMI/MHL serializer. 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 (MAX9280B). Two GPIO ports are included, allowing display powerup 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. Programmable spread spectrum is available on the parallel output. The serial input meets ISO 10605 and IEC 61000-4-2 ESD standards. The core supply is 3.0V to 3.6V and the I/O supply is 1.7V to 3.6V.
The devices are in lead-free, 56-pin, 8mm x 8mm TQFN/SWTQFN packages with exposed pad and 0.5mm lead pitch.
