HMC700LP4 / 700LP4E
v11.0411
8 GHz 16-Bit Fractional-N PLL
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.
