MC44BC373: Multi-Standard PAL/SECAM/NTSC with integrated booster splitter MC44BC374: PAL/NTSC with integrated booster splitter
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 derive 4.
