Hello. i saw a post for quars crystals for the pc engine. now id like to know if someone has 21.477272mhz crystals (2pin) or knows where to get them. im from spain Thanks in advance!
It should be a fairly easy part to get hold of - it's a standard frequency (6 times the NTSC color subcarrier) - this one looks OK: http://www.digikey.com/product-detail/en/ecs-inc/ECS-214.7-S-4/X044-ND/110145 Note that it's specified as being 21.47727Mhz - this is pretty standard since most of those crystals are specced at something like +/- 30ppm and trying to specify the accuracy down to 1Hz is basically meaningless.
