Phase-Locked Oscillator Products
Luff Research offers phase-locked oscillators (PLO) that span the 10 MHz to 32 GHz frequency range. PLO’s are realized in one of the three architectures show below:
Phase-locked oscillators with digital Phase-lock IC:
- Straight forward PLL implementation
- Moderate performance
- High frequency capabilities
- Moderate performance
Phase-locked oscillators with analog sampling phase detector:
-
analog PLL implementation
-
best possible performance
-
FIN typically 10 MHz for CRO units
-
FIN typically 100 MHz for DRO units
Dual loop phase-locked oscillators:
-
analog PLL implementation
-
10 MHz reference or int. reference
-
best possible performance
The implementation of a specific PLO depends on its specific set of requirements:
-
output frequency
-
external reference frequency (or internal reference frequency requirements)
-
required spectral quality (phase noise, spurious and harmonics)
-
power output
-
environmental requirements
PLO requirements will determine the selection of the appropriate fundamental oscillator to be used. These fundamental oscillators operate over the frequency ranges shown.
