Typical Applications

7 GHz INTEGER N SYNTHESIZER

(N = 56 - 519)

v03.0709

The HMC699LP5(E) is a frequency synthesizer with

a wideband reversible polarity digital PFD and lock

detect output. The divider operates unconditionally

from 160 - 7000 MHz with a continuous integer

division ratio of 56 to 519. The HMC699LP5(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 HMC699LP5(E) can be

used to phase lock a VCO to a reference oscillator.

Ultra Low SSB Phase Noise Floor:

-153 dBc/Hz @ 10 kHz offset @ 100 MHz

Reference Frequency.

Programmable Divider (N= 56 - 519) Operating

up to 7 GHz

Interfacing w/ Op-Amp Based Loop Filter

Reversible Polarity PFD w/ Lock Detect Output

Vcc = Vcc1 = Vcc2 = Vcc3 = Vcc_pd = 5V

The HMC699LP5(E) is ideal for:

• Satellite Communication Systems

• Point-to-Point Radios

• Military Applications

• Sonet Clock Generation
