PLL Tuned UHF and VHF Audio/Video High Integration Modulator

Overview The MC44BS373CA is a multi-standard, PAL/SECAM/NTSC modulator. The channel is set by an on-chip high-speed I2C compatible bus receiver. A phase-locked loop (PLL) tunes the modulator over the full UHF range. The modulator incorporates a sound subcarrier oscillator and uses a second PLL to de \n\t•Integrated on-chip programmable UHF oscillator\n\t•No external varicaps diodes/inductor or tuned components\n\t•Extremely low external components count\n\t•Channel 21-69 UHF operation\n\t•VHF range possible by internal dividers (30 MHz to 450 MHz)\n\t•Boosted TVout level (82 dBuV typical)\n\t•H;
