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 4.5, 5.5, 6.0, and 6.5MHz subcarrier frequencies. These frequencies are selectable using the bus.
