... Freescale Semiconductor, Inc. Features 1 Features The MC44BS374CA is a Multi-Standard, PAL/NTSC Modulator. The channel is set by an on-chip high-speed I 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 6.5 MHz subcarrier frequencies. These frequencies are selectable by bus. ...
