boxes, and similar devices. It is designed for applications requiring US broad-
cast, channel 3 or channel 4, RF outputs.
sired channel 3 or 4 frequency is selected using the external package pin, Chan-
nel Selection (CHS). No external tank circuit components are required, reducing
the sensitivity of the PCB design and the need for external adjustments. The PLL
obtains its reference from a 4.0 MHz crystal oscillator.
Sound Oscillator Control (SOC). A fixed Picture to Sound ratio of 12 dB and
4.5 MHz sound subcarrier are used for MC44CC375AV. A low-power standby
mode is selectable via the pin, Power Save (PSAVE), which turns off all internal
VCOs and mixers.
iary Input, pin AUX, which bypasses the sound FM modulator. This direct sound
RF modulator has found more and more applications in BTSC stereo systems.
