I am designing a PAL to NTSC converter in real time and I'm using the adv7180 with adv7343 , I get PAL CBVS and outputting NTSC CBVS .
I need some help with the adv7343 configuration :
sd timing : mode 0 slave
NTSC out .
in the typical application circuit I have some questions :
- what kind of FERRITE BEAD should I use ?
- should I use DAC 1 or DAC 4 for CBVS ?
- If I use DAC 1 what is the optional LPF and is it mandatory ?
- should I use the x16 oversampling or keep the x2 ? and if I use x16 what kind of adjustments I need to do in the circuit ?
- what is the recommended configuration script for my project ?
The ORCAD schema I did until now is attached .
thank a lot
