STW81200: Phase-locked loop (integrated VCO). Company advantage inventory.

describe

STW81200 is a dual architecture frequency

synthesizer (fractional N and integer N),

Features three low phase noise VCOs with

Fundamental frequency range from 3.0 GHz to

6.0 GHz and programmable dual RF outputs

divider stage that can be overridden

46.875 MHz to 6 GHz

STW81200 optimizes size and cost

End application due to integrated low noise LDO regulator and internally matched wideband RF output.

STW81200 is widely compatible

The supplied supply voltage (from 3.0 V to 5.4 V) provides

Very high flexibility for end users

Trade-off for superior performance

dissipation requirements. Low power function

Mode (software control) for extra power

save.

Other features include a crystal oscillator core,

External VCO mode and mute output function
