产品概述

描述

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.
