Other Parts Discussed in Thread: DS90UB926Q-Q1, , DS90UB934-Q1
Hello,
I have several questions regarding FPD LINK III Serializer/Deserializer IC families. I am planning to use DS90UB953-Q1 as a CSI-2 RX {TX: ToF sensor device is compliant with CSI-2(v 1.2) & D-PHY(v 1.2)} device to receive data. I would like to transfer this serialized data with FPD Link III interface over PCB trace(not planning to use a shielded coax / twisted-pair cable) to a device like DS90UB926Q-Q1 which has a LVCMOS output(output number can be less, thus it can be any device with LVCMOS output with FPD LINK III interface).
Block diagram of my design:
Reference: (Interface)Component(Interface)
Tof(CSI-2 v1.2) ->(CSI-2 v1.3)DS90UB953-Q1(FPD LINK III) <-> (FPD LINK III)DS90UB926Q-Q1(LVCMOS) -> (Parallel CMOS)uProcessor
My questions are:
- TX device(ToF sensor) has compatibility with CSI-2(v 1.2) & D-PHY(v 1.2). DS90UB953-Q1 has compatibility with CSI-2(v1.3) & D-PHY(v1.2). I wonder if DS90UB953-Q1 is capable of handling CSI-2 v1.2 communication, which means it has a backward compatibility ?
- Will not using a shielded cable for FPD Link III and using a PCB trace(<5cm for example) cause problems , even considering signal & power integrity topics into consideration ? I don' t think it will but all the application notes and datasheets has diagrams with either shielded coax or twisted pair cable. I assume this is just to point that the link is high speed, TX/RX circuits are far apart and needs careful design regarding SI/PI/EMI ?
- Will using the FPD LINK III interface between different serializer/deserializer IC families cause any problems ? Are the frames differ between or has special fields regarding serializer/deserializer used or the FPD LINK III frames are universal and can be used with any IC which has this interface ? I would like to be sure that the above block diagram will work.
I apologize if a similar question is already asked, which I couldn' t found, thank you for your time in advance.
Kind Regards.
