MAX9276/MAX9280 3.12Gbps GMSL Deserializers for Coax or STP Input and Parallel Output General Description Benefits and Features The MAX9276/MAX9280 gigabit multimedia serial link Ideal for High-Definition Video Applications (GMSL) deserializers receive data from a GMSL serializer Works with Low-Cost 50 Coax Cable and FAKRA over 50 coax or 100 shielded twisted pair (STP) cable Connectors or 100 STP and output deserialized data on the LVCMOS outputs. 104MHz High-Bandwidth Mode Supports 1920x720p/60Hz Display With 24-Bit Color The MAX9280 has HDCP content protection but other- Equalization Allows 15m Cable at Full Speed wise is the same as the MAX9276. The deserializers pair Up to 192kHz Sample Rate And 32-Bit Sample with any GMSL serializer capable of coax output including Depth For 7.1 Channel HD Audio the MAX9293 HDMI/MHL serializer. When programmed Audio Clock from Audio Source or Audio Sink for STP input they are backward compatible with any Color Lookup-Table for Gamma Correction GMSL serializer. CNTL 3:0 Control Outputs 2 The audio channel supports L-PCM I S stereo and up to Multiple Data Rates for System Flexibility eight channels of L-PCM in TDM mode. Sample rates of Up to 3.12Gbps Serial-Bit Rate 32kHz to 192kHz are supported with sample depth up to 6.25MHz to 104MHz Pixel Clock 32 bits. 9.6kbps to 1Mbps Control Channel in UART, Mixed The embedded control channel operates at 9.6kbps to 2 2 UART/I C, or I C Mode with Clock Stretch 2 1Mbps in UART-UART and UART-I C modes, and up to Capability 2 2 1Mbps in I C-I C mode. Using the control channel, a C Reduces EMI and Shielding Requirements can program serializer, deserializer, and peripheral device Programmable Spread Spectrum Reduces EMI registers at any time, independent of video timing, and Tracks Spread Spectrum on Input manage HDCP operation (MAX9280). Two GPIO ports High-Immunity Mode for Maximum Control- are included, allowing display power-up and switching of Channel Noise Rejection the backlight among other uses. A continuously-sampled GPI input supports touch-screen controller interrupt Peripheral Features for System Power-Up and requests in display applications. Verification Built-In PRBS Tester for BER Testing of the Serial For use with longer cables, the deserializers have a pro- Link grammable cable equalizer. Programmable spread spec- Programmable Choice of 8 Default Device trum is available on the parallel output. The serial input Addresses meets ISO 10605 and IEC 61000-4-2 ESD standards. Two Dedicated GPIO Ports The core supply is 3.0V to 3.6V and the I/O supply is Dedicated Up/Down GPI for Touch-Screen 1.7V to 3.6V. Interrupt and Other Uses The devices are in lead-free, 56-lead, 8mm x 8mm TQFN Remote/Local Wake-Up from Sleep Mode and QFND packages with exposed pad and 0.5mm lead Meets Rigorous Automotive and Industrial pitch.
