mc44c401 Summary of contents
Page 1
... The MC44C401 is engineered to process right and left analog audio signals and base- band composite video to generate a stereophonic composite signal in accordance with BTSC system standards. The MC44C401 is designed to output this signal to a Motorola RF modulator, which in turn produces a stereo encoded RF channel for use with any BTSC stereo television receiver ...
