Typical Applications

7 GHz INTEGER N SYNTHESIZER

CONTINUOUS (N = 56 - 519), NON-CONTINUOUS (N = 16 - 54)

v05.0110

The hMC699LP5(E) is a frequency synthesizer with

a wideband reversible polarity digital PFD and lock

detect output. The divider operates from 160 - 7000

Mhz with a continuous integer division ratio N = 56

to 519 and non-continuous division ratio N = 16 to

54. 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. For continuous

division ratio, the A counter and s counter must

satisfy the condition: A + 1 ≥ s.

Ultra Low ssB Phase Noise Floor:

-153 dBc/hz @ 10 khz offset @ 100 Mhz

Open Collector Output Buffer Amplifiers for

Interfacing w/ Op-Amp Based Loop Filter

Reversible Polarity PFD w/ Lock Detect Output

The hMC699LP5(E) is ideal for:

• satellite Communication systems

• Point-to-Point Radios

• Military Applications

• sonet Clock Generation
