Order Code STW81200T STW81200TR Package VFQFPN36 VFQFPN36 Packing Tray Tape and reel 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 to cover 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 broadband matched RF outputs. The STW81200 is compatible with a wide range of supply voltage (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. DocID025943 Rev 2 1/53
