We sell three types of cables for the Saturn. A universal sync on luma which is compatible with both PAL and NTSC regions and also two separate CSYNC versions for the PAL and NTSC. The NTSC version of the Saturn is capable of outputting composite sync (CSYNC) from AV pin number 1, which gives the purest sync output from the console. And our Saturn NTSC CSYNC RGB SCART cable is optimised to work on both the NTSC model 1 and NTSC model 2 Saturns without stability issues, which is achieved using a 220uF capacitor and 470 ohm resistor in series on the sync line. Warning! our NTSC CSYNC cable should not be used on a PAL Saturn, as pin 1 on the AV output of a PAL Saturn doesn't output CSYNC, instead it outputs DC voltage which means it will not function. Therefore we sell a separate cable for the PAL console which incorporates a sync separator circuit inside the cable called an LM1881, which takes the sync over composite video signal and strips out the composite video and outputs CSYNC. This CSYNC cable for the PAL is also compatible with the NTSC. Confusing hey!
