SP8858 Datasheet (Mitel Networks) - 15GHz Professional Synthesiser

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
