Title: 5V from 6260 chip (sync pin 44)
Post by: atman on June 22, 2016, 08:27:57 PM

Testing the continuity from the 6260 chip before i will pass it trough the RGB-amp.
Getting 4.1V from the RGB-lines to ground, unamplified voltage that is.

Also noticed that the sync outputs 5V (pin44), composite out outputs like 1.5V correctly.

How come all outputs so high values?

Is this correct?, seems a bit high?
Thougt the output was around 1.5-2.1V?

C-sync from the hu6260 chip does put out close to 5 volts. Typically 4.7v. This is completely normal.
