Multi-Standard Audio/Video Modulator Antenna Booster/Splitter

Overview The MC44BC374 is a single or dual output, phase-locked loop (PLL) tuned, ultra high frequency (UHF) and very high frequency (VHF), audio/video (A/V), high integration modulator, integrated circuit (IC). It isintended for use in VCRs, games, and set-top box systems. The MC44BC374B has dual t \n•No external varicaps diodes/inductor or tuned components\n•Channel 21-69 UHF operation\n•VHF range possible by internal dividers (30 MHz to 450 MHz)\n•Integrated on-chip programmable UHF oscillator\n•Extremely low external components count\n•High-speed read and write I2C-bus compatible (800 kHz)\;
