TDA6142-5X Datasheet, PDF (1/10 Pages) Siemens Semiconductor Group – FM-Demodulator for SAT TV with Switchable Input

FM-Demodulator for SAT TV with
Switchable Input
TDA 6142-5X
Preliminary Data
Features
q High input sensitivity results in excellent carrier/noise
behaviour
q Reduced noise bandwidth for the prescaler with 480-MHz
LC circuit
q Limitation of the prescaler's internal bandwidth to 960 MHz
q Due to the LC circuit improvement stability against
oscillations
q Interferences reduced by damping higher frequencies with
LC circuit
q Switch for double SAW filter input integrated.
