Part Number: TCA4311A
We are failed to config 0xFE device, but for other I2C address is ok. And competitor-PCA9511ADP is also OK to config 0xFE.
We compare TI-TCA4311ADGKR and NXP-PCA9511ADP, the spec is all the same.
In below figure, we find CLK input (EM_I2C_SCL_U155) have clock in TCA4311ADGKR, and do not find CLK input EM_I2C_SCL_U155 in PCA9511ADP.
It looks these clocks cause IO module confused.
Please kindly give us some suggestion about where does the clock come from? And how to delete it.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to TRX Bobby:
I believe the 8.2 functional block diagram is incorrect in terms of the 2 mA current source. The TCA4311A does not use a current mirror to generate its pull up current, the current actually follows the I(t) curve of a charging capacitor. The 8mA spec is more accurate though it is dependant on the Vcc and any series impedance to the bus capacitance.
