Other Parts Discussed in Thread: SN74LVC2G34, SN74LVC2G17
Originally Processor 1 and Processor 2 had data to transmit, 24MHz Clock.
Since I want to extend the length of the wiring. So I use TXB0104 for this design.
The bottleneck currently seen is,
The signal of TXB0104 of the first level alone is OK (TXB0104-Oscilloscope-20201218-01)
The signal NG after connecting to the second-level TXB0104 (TXB0104-oscilloscope-20201218-02, it looks like it has oscillated)
Oscilloscope
channel 1 --- TXB0104 input of the first level
channel 2 --- TXB0104 output of the first stage (also TXB0104 input of the second stage)
channel 3 --- TXB0104 output of the second level
Just tried pull high 51k ohm. In addition, adding 82 ohm resistors between the 2 TXB0104s is also invalid.
Considered the last output of the second TXB0104, there will be noise coming in, and 100K is used to ground
After making the above 3 modifications, it will still oscillate.
