Sega Mega Drive Dual Frequency Oscillator Mod Kit
Sega Mega Drive / Genesis Dual Frequency Oscillator (DFO) mod kit 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.
DFO does not change the colour sub-carrier for forced region 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.
The 5V DIL14 is designed to replace metal can oscillators like those found in Sega Mega Drive / Genesis consoles. It is a direct replacement and has the same footprint as the metal can oscillator.
