NTSC Video Signal Delay Elements
MN3814 MN3814S CMOS signal delay elements whose wide bandwidth noise make them ideal video signal processing applications. They contain such components shift register clock driver, 906-stage analog shift register, resampling output amplifier. They sample input using supplied clock signal with frequency 14.32 MHz, four times NTSC color signal subcarrier frequency, after adding attached filter delay, produce independent delays (the horizontal scan period).
