Hi.
J514 select 1-2, the voltage between pin13 and pin14(end) is 3.3V. But when I connect pin13 to ptgrey camera point2 , and connect pin14 connect ptgrey camera point5, the voltage between pin13 and pin14(end) is 1.7V.
When I connect to my gps, the voltage is 1.7V too.
How can I fix that?
Hi, it seems caused by camera, for level shift (TXB0108) you can refer to the datasheet of TI (http://www.ti.com/lit/ds/symlink/txb0108.pdf), it should be no problem if camera point is passive point. Also you can use an external resistor to connect pin 13 to GND to verify if the voltage is still 3.3V.
