With the 1.42 GHz 7447A it'd be 1.40 GHz (multiplier of 10.5), like with the existing but very rare 7447A cards, or 1.47 GHz (multiplier of 11). And with a 1.7 GHz 7448 I guess it wouldn't be a problem to find out the remaining PLL configs for multipliers of 11.5 (1.53 GHz), 12 (1.60 GHz), 12.5 (1.67 GHz) and even 13 (1.73 GHz).
