Description

The STW81200 is a dual architecture frequency

synthesizer (Fractional-N and Integer-N), that

features three low phase-noise VCOs with a

fundamental frequency range of 3.0 GHz to

6.0 GHz and a programmable dual RF output

divider stage which allows coverage from

46.875 MHz to 6 GHz.

The STW81200 optimizes size and cost of the

final application thanks to the integration of low-

noise LDO voltage regulators and internally-

matched broadband RF outputs.

The STW81200 is compatible with a wide range

of supply voltages (from 3.0 V to 5.4 V) providing

to the end user a very high level of flexibility which

trades off excellent performance with power

dissipation requirements. A low-power functional

mode (software controlled) gives an extra power

saving.

Additional features include crystal oscillator core,

external VCO mode and output-mute function.
