I need a new crystal oscillator for a Blizzard 1230 MKIV but I just wanted to check with those in the know exactly what type I need.
I know it needs to be a 50MHz 8 pin DIL type which is square with 4 legs but I'm not sure about:
3.3v or 5v?
TTL and/or HCMOS?
Load capacitance? I see ranges from 15pF to 50pF.
I sometimes see a mA rating too, usually 18mA or 40mA.
I hear a lower PPM results in a more stable crystal, 50PPM is the lowest I can source, with 100PPM crystals being a bit cheaper and more common, is there much in this PPM value for this purpose?
Any help would be much appreciated
