John : Take a look.https://chihaukam.blogspot.com/2023/10/me-indeed-is-there-any-indias-spy-in.html?m=1 . It mention about a double in/out operational amplifier. 

.

Me: Ok.

.

John : See the 2nd  Picture above.  We use Rd+ and TX+ to create a Clk line. 

.

Me: This clock line is an Alternate current. 

.

John : Yes, now, b1 send a signal to the input (-) of the operational amplifier. 

.

Me: How many voltage is this signal ?

.

John : 4.5 V.

.

Me: Ok.

.

John : In fact, only Tx- is induced 4.5 V. Tx+ is  only induced 0.5 V. Why ? Because,  the current direction of Tx+ isn't clear yet.

.

Me: Common mode block the direction of the current flow of (Tx +).

.

John : Yes, however,  during the next round, the direction of current flow will be changed.  

.

Me: Yes, by then, Tx+ will be in a favorable situation.  

.

John: Something like the below,

.

If (electrical current = left)

{

TX- = favorable 

TX+ = unfavorable (the direction of current flow is not yet clear.)

}

else 

{

TX- = unfavorable (the current flow is not yet clear)

TX+ = favorable 

}
