Description
Sony PlayStation Multi Output Frequency Oscillator (MOFO) Mod Kit
The multi output frequency oscillator is a dual clock mod for the Sony PlayStation that provides correct GPU timings and correct subcarrier clock depending on the region of the console. The MOFO also has an additional fixed subcarrier clock output for PAL60 operation.
What is the difference between a DFO, MFO , and MOFO?
- The Dual Frequency Oscillator (DFO) provides an auto switching GPU clock output.
- The Multi Frequency Oscillator (MFO) provides an auto switching GPU clock output and an auto switching subcarrier clock output.
- The Multi Output Frequency Oscillator (MOFO) provides an auto switching GPU clock output, an auto switching subcarrier clock output, and an additional fixed subcarrier clock output.
Compatibility
The MOFO should be compatible with all revisions of PlayStation. Not all have been tested yet to confirm. The following table is only a general rule until they can be tested.
| Correct GPU Clock for 50Hz & 60Hz | Correct Subcarrier Clock for PAL & NTSC | Force PAL60 | |
| DFO | PU-8, PU-18, PU-20, PU-22, PU-23, PM41. | PU-8, PU-18. | |
| MFO | PU-8, PU-18, PU-20, PU-22, PU-23, PM41. | PU-8, PU-18, PU-20, PU-22, PU-23, PM41. | |
| MOFO | PU-8, PU-18, PU-20, PU-22, PU-23, PM41. | PU-8, PU-18, PU-20, PU-22, PU-23, PM41. | PU-8, PU-18, PU-20, PU-22, PU-23, PM41. |
PU-8 / PU-18
- GPU Output is necessary for correct GPU clock in 50Hz and 60Hz console modes.
- Subcarrier Output A is not necessary because the GPU creates the correct PAL & NTSC subcarrier clocks in all regions.
- Subcarrier Output B can be used to force PAL60 operation for use with TVs that are incompatible with NTSC signals.
PU-20 / PU-22
- GPU Output is necessary for correct GPU clock in 50Hz and 60Hz console modes.
- Subcarrier Output A is necessary to get correct PAL & NTSC subcarrier clocks in all regions.
- Subcarrier Output B can be used to force PAL60 operation for use with TVs that are incompatible with NTSC signals.
Recommended Dual Clock Mod
PU-8 / PU-18
- If using RGB = DFO
- If using composite video & a dual format PAL/NTSC TV = DFO
- If using composite video & a single format PAL TV = MOFO (Sub-B Out)
PU-20 / PU-22 / PU-23 / PM-41
- If using RGB = DFO
- If using composite video & a dual format PAL/NTSC TV = MFO/MOFO (Sub-A Out)
- If using composite video & a single format PAL TV = MOFO (Sub-B Out)
