| 14 | The MAX96712 deserializer converts GMSL2 or GMSL1 serial inputs into MIPI |
| 15 | CSI-2 D-PHY or C-PHY formatted outputs. The device allows each link to |
| 16 | simultaneously transmit bidirectional control-channel data while forward |
| 17 | video transmissions are in progress. The MAX96712 can accommodate as many as |
| 18 | four remotely located sensors using industry-standard coax or STP |
| 19 | interconnects. |
| 20 | |
| 21 | Each GMSL2 serial link operates at a fixed rate of 3Gbps or 6Gbps in the |
| 22 | forward direction and 187.5Mbps in the reverse direction. In GMSL1 mode, the |
| 23 | MAX96712 can be paired with first-generation 3.12Gbps or 1.5Gbps GMSL1 |
| 24 | serializers or operate up to 3.12Gbps with GMSL2 serializers in GMSL1 mode. |
