EVALUATION KIT AVAILABLE MAX9275/MAX9279 3.12Gbps GMSL Serializers for Coax or STP Output Drive and Parallel Input General Description Benefits and Features The MAX9275/MAX9279 are 3.12Gbps Gigabit Multimedia Ideal for High-Definition Video Applications Serial Link (GMSL) serializers with parallel LVCMOS Drives Low-Cost 50 Coax Cable and FAKRA inputs and a CML serial output programmable for 50 Connectors or 100 STP coax or 100 shielded twisted pair (STP) cable drive. 104MHz High-Bandwidth Mode Supports The MAX9279 has HDCP content protection but other- 1920x720p/60Hz Display With 24-Bit Color wise is the same as the MAX9275. The serializers pair Serializer Pre/Deemphasis Allows 15m Cable at with any GMSL deserializer capable of coax input. When Full Speed programmed for STP output they are backward compat- Up to 192kHz Sample Rate And 32-Bit Sample ible with any GMSL deserializer. The output amplitude is Depth For 7.1 Channel HD Audio programmable 100mV to 500mV, single-ended (coax) or Multiple Data Rates for System Flexibility 100mV to 400mV differential (STP). Up to 3.12Gbps Serial-Bit Rate 2 The audio channel supports L-PCM I S stereo and up to 6.25MHz to 104MHz Pixel Clock eight channels of L-PCM in TDM mode. Sample rates of 9.6kbps to 1Mbps Control Channel in UART, Mixed 2 2 32kHz to 192kHz are supported with sample depth up to UART/I C, or I C Mode with Clock Stretch 32 bits. Capability The embedded control channel operates at 9.6kbps to Reduces EMI and Shielding Requirements 2 1Mbps in UART-UART and UART-I C modes, and up Serial Output Programmable for 100mV to 500mv 2 2 to 1Mbps in I C-I C mode. Using the control channel, a Single-Ended or 100mV to 400mV Differential C can program serializer, deserializer, and peripheral Programmable Spread Spectrum Reduces EMI device registers at any time, independent of video timing, Bypassable Input PLL for Parallel Clock Jitter and manage HDCP operation (MAX9279). A GPO output Attenuation supports touch-screen controller interrupt requests from Tracks Spread Spectrum on Input the remote end of the link. High-Immunity Mode for Maximum Control- Channel Noise Rejection For use with longer cables, the serializers have program- mable pre/deemphasis. Programmable spread spectrum Peripheral Features for System Power-Up and is available on the serial output. The serial output meets Verification ISO 10605 and IEC 61000-4-2 ESD standards. The core Built-In PRBS Generator for BER Testing of the supply is 1.7V to 1.9V and the I/O supply is 1.7V to 3.6V. Serial Link The MAX9275/MAX9279 are available in a lead-free, Dedicated Up/Down GPO for Touch-Screen 56-pin, 8mm x 8mm, TQFN package with exposed pad Interrupt and Other Uses and 0.5mm lead pitch.
