MAX9278/MAX9282 3.12Gbps GMSL Deserializers for Coax or STP Input and LVDS Output General Description Benefits and Features The MAX9278/MAX9282 gigabit multimedia serial link Ideal for High-Definition Video Applications (GMSL) deserializers receive data from a GMSL serializer 104MHz High-Bandwidth Mode Supports over 50 coax or 100 shielded twisted-pair (STP) cable 1920 x 720p/60Hz Display with 24-Bit Color and output deserialized data on 3 of 4 data-lane LVDS Works with Low-Cost 50 Coax Cable and FAKRA outputs (oLDI). Connectors or 100 STP The MAX9282 has HDCP content protection but other- Equalization Allows 15m Cable at Full Speed wise is the same as the MAX9278. The deserializers pair Up to 192kHz Sample Rate and 32-Bit Sample with any GMSL serializer capable of coax output. When Depth for 7.1 Channel HD Audio programmed for STP input, they are backward compatible Audio Clock from Audio Source or Audio Sink with any GMSL serializer. Color Lookup Table for Gamma Correction CNTL 3:0 Control Outputs 2 The audio channel supports L-PCM I S stereo and up to eight channels of L-PCM in TDM mode. Sample rates of Multiple Data Rates for System Flexibility 32kHz to 192kHz are supported with sample depth up to Up to 3.12Gbps Serial-Bit Rate 32 bits. 6.25MHz to 104MHz Pixel Clock 9.6kbps to 1Mbps Control Channel in UART, The embedded control channel operates at 9.6kbps 2 2 2 UART-to-UART, UART-to-I C, or I C-to-I C 2 to 1Mbps in UART-to-UART and UART-to-I C modes, Modes with Clock Stretch Capability 2 2 and up to 1Mbps in I C-to-I C mode. Using the control channel, a C can program serializer, deserializer, and Reduces EMI and Shielding Requirements peripheral device registers at any time, independent of Programmable Spread Spectrum Reduces EMI video timing, and manage HDCP operation (MAX9282). Tracks Spread Spectrum on Input Two GPIO ports are included, allowing display power- High-Immunity Mode for Maximum Control- up and switching of the backlight among other uses. A Channel Noise Rejection continuously sampled GPI input supports touch-screen Peripheral Features for System Power-Up and controller interrupt requests in display applications. Verification For use with longer cables, the deserializers have a Built-In PRBS Tester for BER Testing of the Serial programmable cable equalizer. Programmable spread Link spectrum is available on the LVDS output. The serial input Programmable Choice of Nine Default Device and LVDS output meet ISO 10605 and IEC 61000-4-2 Addresses ESD standards. The core supply is 3.0V to 3.6V and the Two Dedicated GPIO Ports I/O supply is 1.7V to 3.6V. Dedicated Up/Down GPI for Touch-Screen Interrupt and Other Uses The devices are in lead-free, 48-pin, 7mm x 7mm Remote/Local Wake-Up from Sleep Mode TQFN and side-wettable TQFN (SWTQFN) packages with exposed pad and 0.5mm lead pitch.
