ST STW81200TR

无LVDS，LVPECL时钟

Overview

The STW81200T 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 STW81200T 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 STW81200T 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.
