Edit: am populating one of borti's SNES RGB Bypass Board Vers. 4.1a ( with_csync )
I will be using a PAL SCART cable, to use the existing 12V on SCART pin 8; automatically setting the TV to 4:3 aspect ratio.
borti's pcb ( for use with NTSC cable )
AV Port pin 3 = c-sync
AV Port pin 9 = not connected ( composite video )
My PAL SCART cable ( with 75ohm
AV Port pin 3 = 12V
AV Port pin 9 = c-sync
- cut trace from R43
- wire jumper cable from R43 to AV pin 9
---------------------------------------------------------------------------------------------
To use a pure h+v sync signal as opposed to the existing composite or luma signals.
Is a line driver circuit required for the current draw from a 'typical modern LCD'?
BA6592F
Icc 38 mA Vr=Vg=Vb = 0.7Vp-p
Is this the maximum current rating? does this apply to the sync output?
SONY LCD KDL-40
1/75 = 0.0133 = 13.3 mA
Is this the correct equation for the TV's maximum input current draw?
Would anyone like to check my circuit please
Yes I might order borti's SNES RGB Bypass Board Vers. 4.1a
mostly this is self education in 'tronics
