behaviour
Reduced noise bandwidth for the prescaler with 480-MHz
LC circuit
Limitation of the prescaler's internal bandwidth to 960 MHz
Due to the LC circuit improvement stability against
oscillations
Interferences reduced by damping higher frequencies with
LC circuit
Switch for double SAW filter input integrated.
