Hi:
Does anybody have any SCHEMATICS  of these things?  Particularly the
PLL/VCO stages?  Or at least an ID on the PLL chips which can be used to
get a data sheet?l  (I've had no luck searching using the numbers
stamped on the chips, other than the obvious 74hc series.)

Any info appreciated.  Thanks!

73,
Jim
