The HMC702 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 VCO s. In addition the synthesizer has a number of auxiliary clock generation modes that can be accessed via the GPO.
