Part Number: DS90UB933-Q1
The overall hardware block diagram is as follows:
1, video output impedance 50 ohm
2. CPU model: Ti J6
Video IC model: ds90ub933artvrq1
3. Only video signal is transmitted on the coaxial line without POC circuit
4. The pin corresponds to d2-d9
5. Output video 720P@30FPS
6. Signal format: bt656, embedded with synchronous signal, and the timing requirement is less than 256bytes. See the attachment for details.
7. The corresponding schematic screenshot is as follows, including bt656 input, I2C address and impedance
The current problems are as follows:
1. After decoding with ds90ub936, there is no CSI signal output
The following investigations have been carried out:
1. You can see the picture when you test 936 with pattern generator,
2. The ds90ub933 register data can also be obtained through 936 I2C transmission
3. But the ds90ub936 CSI measured by oscilloscope doesn't see any data output
There are some questions:
1. Ds90ub936 does not support decoding bt656 (added Hsync + Vsync signal)?
Please help to solve the above problems and questions;
thank you!
