PLL Tuned VHF (Channel 3 / 4) Audio / Video Modulator
MC44CC375AV
The MC44CC375 CMOS RF modulator is the latest generation of the legacy MC44BC375 products. www.datasheet4u.com The MC44CC375AV is an audio/video RF modulator for use in VCRs, set-top PLL TUNED VHF boxes, and similar devices. It is designed for applications requiring US broad(CHANNEL 3/4) cast, channel 3 or channel 4, RF outputs. AUDIO/VIDEO MODULATOR A programmable Phase-Locked Loop (PLL) tunes the modulator, and the desired channel 3 or 4 frequency is selected using the external package pin, Channel Selection (CHS). No external tank circuit components are required, reducing the sensitivity of the PCB design and the need for external adjustments.
