Monolithic Linear IC
LA7770
FSK Receiver for CATV Use
Overview
The LA7770 is a CATV-oriented wide-band FSK (fre-
quency shift keying) receiver IC encapsulated in a DIP20S
package that incorporates the functions required to demodu-
late scramble decoding data (i. e., the oscillator, mixer, lim-
iting IF amplifier, squelcher, and data shaper functions).
