John : Take a look. https://johnchihau.blogspot.com/2026/06/blog-post_16.html?m=1.It mention about how GPS form a clock line .

Me: Ok.

John : Take a look.https://chihaukam.blogspot.com/2024/09/blog-post_13.html?m=1. It said if the input vote is above 3V, the output is 1. Else, the output is 0.

Me: Ok.

John : See the Picture above. Route A is higher than Route B in term of Voltage,  therefore, the Clock line is on Up Cycle. 

Me: The clock line is based on differential pair.

John : Correct.  However,  the data input isn't based on differential pair.  

Me: The data input of GPS is based on Level trigger.  If the voltage is above 3V, the data input is 1, else,  the data input is 0.

John : Correct.
