Other Parts Discussed in Thread: TDES954
I am designing a board that has both a Camera Module (MIPI) and an IMU (I2C). In a previous post it was confirmed that both can be connected to a TSER953 which is then connected over Coax to a TSER954 and then onto the ISP. I am a little confused regarding the I2C remote host/slave configuration. Here a few a questions that I have.
- Is it possible to simply have both the Camera Module and IMU as Slaves and the TSER953 acting as a Remote Host?
- If so, can the SCL and SDA pins on the Camera Module and IMU connect together on a single path to the SCL & SDA pins on the TSER953? (Pullup resistors between TSER953 and junction of SCL/SDA.)
- Or, would I need to add a Serial Control Bus (i.e. I2C Switch or I/O Expander) on the board that connects to the TSER953 SCL/SDA pins and then communicates to the Camera Module and IMU?
- How do I confirm that the Camera Module and the IMU have distinct addresses both on the pin connection and on the software register? Is this where the IDX pin comes into play?
Thank you for your time!
All the best,
