EVALUATION KIT AVAILABLE MAX9277/MAX9281 3.12Gbps GMSL Serializers for Coax or STP Output Drive and LVDS Input General Description Features and Benefits The MAX9277/MAX9281 are 3.12Gbps Gigabit Multimedia Ideal for High-Definition Video Applications Serial Link (GMSL) serializers with 3- or 4-data lane LVDS Drives Low-Cost 50 Coax Cable and FAKRA input (oLDI) and a CML serial output programmable for Connectors or 100 STP 50 coax or 100 shielded twisted pair (STP) cable drive. 104MHz High-Bandwidth Mode Supports The MAX9281 has HDCP content protection but other- 1920x720p/60Hz Display With 24-Bit Color wise is the same as the MAX9277. 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- ible with any GMSL deserializer. The output amplitude is Up to 192kHz Sample Rate and 32-Bit Sample programmable 100mV to 500mV single-ended (coax) or Depth For 7.1 Channel HD Audio 100mV to 400mV differential (STP). Multiple Data Rates for System Flexibility 2 The audio channel supports L-PCM I S stereo and up to Up to 3.12Gbps Serial-Bit Rate eight channels of L-PCM in TDM mode. Sample rates of 6.25MHz to 104MHz Pixel Clock 32kHz to 192kHz are supported with sample depth up to 9.6kbps to 1Mbps Control Channel in UART, 32 bits. 2 2 mixed UART/I C, or I C Mode with Clock Stretch The embedded control channel operates at 9.6kbps to Capability 2 1Mbps in UART-UART and UART-I C modes, and up to 2 2 Reduces EMI and Shielding Requirements 1Mbps in I C-I C mode. Using the control channel, a C can program serializer, deserializer and peripheral device Serial Output Programmable for 100mV to 500mV registers at any time, independent of video timing, and Single-Ended or 100mV to 400mV Differential manage HDCP operation (MAX9281).
