HMC702LP6CE
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.
