SL1451
WIDEBAND PLL FM DETECTOR FOR SATELLITE TV
The SL1451 is a phase locked loop demodulator for use in
wideband FM systems. It is intended for use with an IF input
frequency from 300MHz to 700MHz in satellite receivers. It
consists of an input RF amplifier, signal level detector, UHF phase
detector UHF oscillator and video/loop amplifier. Both positive
and negative going video outputs are available.
FEATURES
■ Complete PLL System for Wideband FM Demodulator
■ Noise Threshold Performance: 8dB (Typ.)
■ Low External Component Count
■ Positive and Negative going Video Output
■ Demodulates FM Signals with up to 28MHz p-p
