Only to the extent that the VTI one will work if that capacitor happens to be missing/faulty, while the Ferranti one requires that it is present.Am I right in thinking that slightly different external circuitry is required for these two chips? There was that whole business with the Ferranti device relying on an external capacitor in order to blip DCD. (related thread)
The capacitor is used for a timer; the VTI does the timing digitally and so simply doesn't use the pin with the capacitor connected to it at all.
