HMC702LP6CE
14 GHz 16-BIT FRACTIONAL-N PLL

General Description
The HMC702LP6CE is a SiGe BiCMOS fractional-N PLL. The fractional-N PLL includes a fixed divide by 2 followed by
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.
The fractional-N PLL features an advanced delta-sigma modulator design that allows ultra-fine frequency step sizes.
The fractional-N PLL 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 fractional-N PLL 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.
In addition the fractional-N PLL has a number of auxiliary clock generation modes that can be accessed via the GPO.
