Spurious outputs are low enough to eliminate the need for costly Direct Digital Synthesis (DDS) references in many applications. t he HMc 700LP4(E) phase-frequency detector (PFD) features cycle slip prevention (c SP) technology that allows faster frequency hopping times. Ultra low in-close phase noise and low spurious also permit architectures with wider loop bandwidths for faster frequency hopping and low micro-phonics. FSK mode allows the synthesizer to be used as a simple low cost direct FM transmitter source. r ecommended level >500mVpp. With 250mVpp phase noise degradation may occur.
