The MAX9278A/MAX9282A 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 3 of 4 data-lane LVDS outputs (oLDI).

The MAX9282A has HDCP content protection but otherwise is the same as the MAX9278A. 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 (MAX9282A). 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. Programmable spread spectrum is available on the LVDS output. The serial input and LVDS output meet 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, 48-pin, 7mm x 7mm TQFN/SWTQFN and QFND packages with exposed pad and 0.5mm lead pitch.

Product Detail

The MAX9278A/MAX9282A coax evaluation kits (EV kit) provide a proven design to evaluate the MAX9278A/MAX9282A high-bandwidth gigabit multimedia serial link (GMSL) deserializers with spread spectrum and full duplex control channel with the use of a standard FAKRA coaxial cable. 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 device. The EV kit comes with a MAX9278AGTJ/V+ or MAX9282AGTJ/V+ installed.

For complete GMSL evaluation, using a standard FAKRA coaxial cable, order the MAX9278A/MAX9282A coax EV kit and a companion serializer board (MAX9275/MAX9279 coax EV kit referenced in this document). For evaluating with STP cable, also order the MAXCOAX2STP-HSD adapter kit and refer to its data sheet. Only one adapter kit is required per link, connecting the serializer and deserializer (SerDes) boards.

Applications

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