Tool/software:
I'm trying to get an I2C bus through a sealed plastic enclosure and plan to use an optical link, where SDA and SCL each have a LED+PD on the Host side, and the Client will have the same corresponding circuitry.
I came across another E2E post confirming that the P82B96 can be used to implement an I2C "optical bridge": "If you really wanted to use optical signals, you would need to use a P82B96 on each side to get unidirectional signals, and then add optical transmitters and receivers to the Tx/Rx/Ty/Ry pins."
Do you have any app notes, reference designs, or advice to share? I'm concerned about how well this handles bidirectional communication on SDA.
I'm also looking at the NXP SC16IS7xx SPI or I2C-to-UART Bridge to do this optical scheme, but it seems like a lot of data-layer configuration mess which I would rather avoid. A pure hardware solution with the P82B96 would be fantastic.
