ODM Posted May 12, 2011 Report Share Posted May 12, 2011 The datasheet for YMF262 lists the chip requiring a clock of 10 to 16 MHz. Will it suffer if left unclocked, and should clock be established at the same time as the power supply? Has anyone built a Midibox-FM without supplying a clock for the YMF262 chip?

TK. Posted May 12, 2011 Report Share Posted May 12, 2011 Will it suffer if left unclocked, and should clock be established at the same time as the power supply? This isn't specified in the datasheet, but I think that the clock could also start later. Has anyone built a Midibox-FM without supplying a clock for the YMF262 chip? This won't work, as the clock is used to generate the audio frequencies. The OPL3 has no inbuilt oscillator. Btw.: why are you asking? If you are planning to build a MBFM, the 14.318 MHz oscillator is required, otherwise the oscillator pitches won't be correctly tuned. Best Regards, Thorsten.
