Hello,
I am attempting to use a TXB0108 for a SPI 5V to 3.3V interface. The SCK signal looks like the following picture.
Signal 3 (purple) is the input to the level shifter, and signal 2 (blue) is the output. The clock period seems to be about half. The levels are correct, but the timing is off. Please advise. Each bit time is 8 microseconds which is slower than the maximum 100 Mbps. What could be causing this?
Thanks!
