SL1451
WIDEBAND PLL FM DETECTOR FOR SATELLITE TV
The SL1451 is a phase locked loop demodulator for use inwideband FM systems. It is intended for use with an IF inputfrequency from 300MHz to 700MHz in satellite receivers. Itconsists of an input RF amplifier, signal level detector, UHF phasedetector UHF oscillator and video/loop amplifier. Both positiveand negative going video outputs are available.LOOP FEEDBACK 10VOSCILLATOR EMITTER12345678
