| HMC698LP5 / 698LP5E v03.0709 7 GHz INTEGER N SYNTHESIZER (N = 12 - 259) Typical Applications The HMC698LP5(E) is ideal for: * Satellite Communication Systems * Point-to-Point Radios * Military Applications * Sonet Clock Generation Features Ultra Low SSB Phase Noise Floor: -153 dBc/Hz @ 10 kHz offset @ 100 MHz Reference Frequency. Programmable Divider (N= 12 - 259) Operating up to 7 GHz Open Collector Output Buffer Amplifiers for Interfacing w/ Op-Amp Based Loop Filter Reversible Polarity PFD w/ Lock Detect Output 32 Lead 5x5mm SMT Package: 25mm 2 11 PLL - INTEGER-N SYNTHESIZER - SMT Functional Diagram General Description The HMC698LP5(E) is a frequency synthesizer with a wideband reversible polarity digital PFD and lock detect output. The divider operates unconditionally from 80 - 7000 MHz with a continuous integer division ratio of 12 to 259. The HMC698LP5(E) high frequency operation along with ultra low phase noise floor make possible synthesizers with wide loop bandwidth and low N resulting in fast settling and very low phase noise. When used in conjunction with a differential loop filter, the HMC698LP5(E) can be used to phase lock a VCO to a reference oscillator.
