Analog Devices / Maxim Integrated MAX96751 GMSL2 Serializers with HDMI 2.0 Input
Analog Devices / Maxim Integrated MAX96751 GMSL2 Serializers with HDMI 2.0 Input convert HDMI® to single or dual GMSL™ serial protocol. These devices also send and receive 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 Analog Devices / Maxim Integrated MAX96751 supports RGB888 video at up to 215MHz PCLK per GMSL2 link. 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 eight 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.
