SP8858 Datasheet - Mitel Networks

SP8858 15GHz Professional Synthesiser

FPD = M divider output pulses = RF input frequency 4(MN1A) when SENSE bit in the programming word = ‘0’. When SENSE bit = 1, this pin is FREF = R divider output pulses = reference input frequency 4R. (see Data Entry and Control description and Fig. 6). FREF = R divider output pulses when SENSE bit i.
