It provides RF signals with negative or positive video modulation and AM or FM sound subcarrier to satisfy both PAL/NTSC and SECAM applications. The on-chip local oscillator uses an external resonator tank which may be controlled via any Mitel 1.3GHz synthesiser. Selection of both video and sound standards are provided by level switching of a single pin. A video AGC circuit is provided to ensure constant modulation depth. In PAL mode this may be disabled and a white clip circuit switched in to prevent overmodulation if desired.
