Sony PlayStation Dual Frequency Oscillator (DFO) is designed to switch the video refresh rate between more accurate and stable 50Hz and 60Hz as compared to running region modified consoles in non-native video refresh rates.

A DFO in a PlayStation does not change the colour subcarrier for the forced region to have colour over composite and RF.

It is important that you know what you are doing with these and know their intended purpose and how much benefit this might bring.

3.3V SMD Dual Frequency Oscillator

This low profile 3.3V SMD version is perfect for bottom mount PlayStation installs. This is the absolute best PlayStation Dual Frequency Oscillator available.
