Arduino and a YMZ294
volume is low, you can see me in reflection ... I know ... hope you like it anyway.

square signal on just one pin, so no crystal here (unlike what you would have next to your Atmel MCU). Anything that makes a square signal will do the trick, but must be in range 1MHz to 8Mhz.
So, by reading the japanese documentation provided by Akizuki, I got it is the same as a YMZ284 (YMZ294 has 2 extra pins, one for test mode and the other one for choosing the crystal frequency 4/8 MHz). Wiring is the same as YMZ284 therefore.
And to me it looks like also its friend the YM2149. So I put these documentations here :
