STW81200TR

STW81200TR is a wideband RF PLL fractional/integer frequency synthesizer with integrated VCOs and LDOs. It is a dual architecture frequency synthesizer (Fractional-N and Integer-N) that features three low phase-noise VCOs with a fundamental frequency range of 3.0GHz to 6.0GHz and a programmable dual RF output divider stage which allows coverage from 46.875MHz to 6GHz. It is compatible with a wide range of supply voltages (from 3.0V to 5.4V) providing the end user a very high level of flexibility. This frequency synthesizer gives 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. This frequency synthesizer is ideal for application such as cellular/4G infrastructure equipment, instrumentation and test equipment, cable TV, other wireless communication systems etc.
