AN3672NFBP
Audio signal processor IC for HiFi VCR
incorporating EIAJ sound multiplex system
s Overview
The AN3672NFBP is a HiFi audio signal processor IC
(NTSC) incorporating EIAJ sound multiplex decoder and
pre/recording amplifier. An adjustment-free sound multi-
plex decoder is realized through both of f_O automatic
adjustment of high precision VCO by a reference signal
(f_SC) and an SIF (4.5 MHz inter-carrier sound intermediate
frequency) signal input.
s Features
• Built-in EIAJ sound multiplex decoder
• Full adjustment-free by SIF signal input
• f_O automatic adjustment of high precision VCO
• Built-in pre/recording amplifier
s Applications
• HiFi VCR
