PTN3356 DisplayPort to VGA.
PTN3356 has ROM type and Flash type.
We used both ROM type and Flash type, but didn't work.
We designed Schemetics that is copyed NXP reference, so we think Schemetics is no problem.
Does it have to program? Does it need a program using tool?
1) Crystal scope : 27MHz XTAL at power on,
oscilator about 1msec and disappear 27M waveform.
2) Realtek's DP to VGA module: It works well when we attach DP to VGA module to our DP port,
