The MAX9276A and MAX9280A 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 (MAX9280A). Two GPIO ports are included, allowing display power-up and switching off 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. A 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 Analog Devices MAX9276A & MAX9280A 3.12Gbps GMSL Deserializers are available in lead-free, 56-pin, 8mm x 8mm TQFN and SWTQFN packages with exposed pad and 0.5mm lead pitch.
