Hello,
one of our customer is currently creating a concept for a "remote" camera.
The camera should be up to one meter away from the processor board. To bridge this distance they need a serializer on the camera module and a deserializer on the processor module
- The serializer on the camera module should support the resolution/frames per second of the Image Sensor/ISP. This is important to them for future (more powerful) processor modules.
- For the serializer they favor the DS90UB953.
- For the deserializer on the processor module, they favor the DS90UB934 due to the parallel interface
- As a connection between the two modules they want to use a USB 3.0 cable (Super Speed data signal)
The block diagram looks like this:
What I would like to know:
- Is a USB 3.0 cable (Super Speed Data Signal) with 90Ohm impedance suitable as an interface between serializer and deserializer.
According to the datasheet (ds90ub953-q1) page 10, the impedance for STP (differential) should be 100 ohms.
Is there any experience regarding the use of USB3.0 cables as an interface between serializer and deserializer? - The application report “Backward Compatibility Modes for Operation With Parallel Output Deserializers” (snla270a.pdf) page 4 table 2 shows, that a combination of DS90UB953 and DS90UB934 is only possible with coax cable.
Is there thus no possibility to connect the serializer DS90UB953 and the deserializer DS90USB934 via STP
Thanks and best regards,
Brian
