MAX96714F has one GMSL2 input port and one CSI2 4 lanes output port, MAX96717F has one CSI2 input port and one GMSL2 output port. The drivers support the tunnel mode where all the CSI2 traffic coming from an imager is replicated through the deserializer output port. Both MAX96714F and MAX96717F are limited to a 3Gbps forward link rate leaving a maximum of 2.6Gbps for the video payload.
