产品详情和应用
The MAX96751 serializer converts HDMI® to single or dual GMSL™ serial protocol. It also sends and receives side-channel and peripheral control data, enabling full-duplex, single-wire, transmission of video and bidirectional data. Each GMSL2 link operates at a fixed rate of 3Gbps or 6Gbps in the forward direction and 187.5Mbps in the reverse direction.
The MAX96751 supports RGB888 video at up to 215MHz PCLK per GMSL2 link.
For designs supporting two displays, see the New Designs Supporting Two Displays section of Detailed Descriptions for more information.
The GMSL2 concurrent control channel operates in I2C or UART mode. Two additional pass-through I2C or UART channels and a pass-through SPI channel are provided for peripheral control. The bidirectional audio channel supports I2S stereo and up to 8 channels in Time-Division Multiplexing (TDM) mode.
Data can be transmitted over low-cost 50Ω coax or 100Ω STP cables that meet the GMSL2 Channel Specification. Contact the factory to receive the GMSL2 Channel Specification document.
