General Description

the HMc700LP4(E) is a SiGe BicMoS fractional-n PLL. the PLL includes a very low noise digital phase frequency

detector (PFD), and a precision controlled charge pump.

the fractional PLL features an advanced delta-sigma modulator design that allows both ultra-fine step sizes and very

low spurious products. Spurious outputs are low enough to eliminate the need for costly Direct Digital Synthesis (DDS)

references in many applications.

the HMc700LP4(E) phase-frequency detector (PFD) features cycle slip prevention (cSP) 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.

recommended level >500mVpp. With 250mVpp phase noise degradation may occur.
