Hello,
Q1) Is there a good in-stock chip solution to be used as a I2C bus extender?
We have a product with 2m long I2C communication between a master unit and slave peripheral unit that has some bit errors. Management would like to avoid not using I2C with the goal of avoiding software development.
I see that LTC4331 (I2C Slave Device Extender Over Rugged Differential Link) is not in stock right now.
In this forum at the below post, it is written not to use the LTC4310 over long distance. I have ordered an evaluation board and it will be here next week.
(Missing Forum Thread)
The same post suggest the LT3960 (I2C to CAN-Physical Transceiver). It is not in stock today either
Q2) Does galvanic ground isolation give a performance enhancement? I need to pass EMC EMI testing. I care mostly about no bit errors. Our slave peripheral unit is powered by the master unit through the same cable that passes I2C.
Thanks,
Frank
