Another interesting component is (was) the Motorola MC1378 video overlay
synchronizer. Put NTSC in and get everything out, including phase locked
10xSc clock (35.8 Mhz). External circuitry has to feed H sync back to the
chip - we accomplished that with one PAL. The thing also had RGB and
overlay enable inputs. Anyway, what we worked with was a pre-production
sample (labelled XC1378), and I haven't heard whether or not these things
ever made it to full production. Anyone got more info?
