Title: Sega dreancast eye pattern
Post by: davidrayel on May 03, 2023, 12:23:46 PM

I have the Sega Dreancast xv779 board and I need to measure the optical eye pattern but I don't know what the test point is. Anyone who can help I'll be grateful.

No idea, the schematic I made for that board awhile back is here. Might be of some use. - https://acidmods.com/forum/index.php?topic=44892.0

I found the RF output IC (IC1 313-5635) but I didn't find its datasheet. I will solder 7 wires (to test the closed drive) in the probable test points that can be the RF output of the eye patern. I'll be back soon with the result
