SP8858 - 1.5GHz Professional Synthesiser

Datasheet Summary

Description

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.
