Hi Team
I want to review schematic of customer.
SENSOR_RSTN and SENSOR_CLK are PUSH-PULL type.
So, I connected PULL-UP to A PORT (SENSOR SIDE) only.
SENSOR_CLK is 37.125MHz, 200ohm is connected to B port, 100ohm is connected to A port.

Hi Charles,
There's a video series that explains how to design with the LSF family in detail located here:
https://training.ti.com/logicminute
As long as the SENSOR_RSTN and SENSOR_CLK drivers can handle the total current sink -- 3.3V @ 200 ohm and 100 ohm @ 1.8V will produce a total of (1.8/100) + (3.3/200) = 34.5mA -- then I don't see any problems. The only other factor will be the parasitic capacitance, but with typical values (15pF) I would expect this to work without any problems.
