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