Sony PlayStation Multi Frequency Oscillator Mod Kit

Description

Sony PlayStation Multi Frequency Oscillator (MFO) Mod Kit

The multi frequency oscillator (MFO) is a dual clock mod for the Sony PlayStation that provides a correct GPU clock and a correct subcarrier clock for both 50Hz/PAL and 60Hz/NTSC console modes.

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

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)
