GMSL2 Deserializer with Dual LVDS (OLDI) Output

The MAX96752 deserializers convert a single- or dual-link GMSL™ serial input to single or dual OLDI. They also send and receive side-channel and peripheral control data, enabling full-duplex, single-wire transmission of video and bidirectional data.

The OLDI output can be configured as single-port (4 or 8 lanes) or dual-port (2 x 4 lanes) for flexibility in driving displays with a variety of resolutions. Each port accommodates pixel clock rates of up to 150MHz, and in dual-port mode, the MAX96752 support a combined pixel clock of up to 300MHz.

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 TDM mode.

Operation is specified over the -40°C to +105°C automotive temperature range. The devices are AEC-Q100 qualified.

Data can be transmitted over low-cost 50Ω Coax or 100Ω STP cables that meet the GMSL2 channel specification.
