14 GHz 16-BIT FRACTIONAL-N SYNTHESIZER
General Description
the hMc702LP6ce is a siGe BicMos fractional-n frequency synthesizer. the synthesizer includes a 8Ghz 16-bit
rf n-Divider, a 24-bit delta-sigma modulator, a very low noise digital phase frequency detector (PfD), and a precision
controlled charge pump. in addition the synthesizer supports an external step tuned Vco.
the fractional synthesizer features an advanced delta-sigma modulator design that allows ultra-fine frequency step
sizes. the synthesizer features the ability to alter both the phase-frequency detector (PfD) gain and the cycle slipping
characteristics of the PfD. this feature can reduce the time to arrive at the new frequency by 50% vs. conventional
PfDs. Ultra low in-close phase noise also allows wider loop bandwidths for faster frequency hopping.
the synthesizer contains a built-in linear sweeper function, which allows it to perform frequency chirps with a wide
variety of sweep times, polarities and dwells, all with an external or automatic sweep trigger.
a General Purpose output (GPo) bus supports the use of multiple Vcos. in addition the synthesizer has a number of
auxiliary clock generation modes that can be accessed via the GPo.
