MC44BC374C General Description
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.
The modulation standard can be chosen using a control bit that selects between System L or System B/ (MC44BC373C only).
The picture-to-sound ratio may be adjusted using the bus. In addition, an on-chip video test pattern generator can be switched ON with a 1KHz audio test signal.

Meets Moisture Sensitivity Level 1, no dry pack required
This device contains protection circuitry to guard against damage due to high static voltage or
electric fields. However, precautions must be taken to avoid applications of any voltage higher
thanmaximum rated voltages to this high impedance circuit. For proper operation, input and
output voltages should be constrained to the ranges indicated in the Recommended Operating
Conditions.
