MN3890S

The MN3890S is a 1 H image delay element of a 4 fSC CMOS CCD and suitable for video signal processing applications.

It contains such components as a frequency-doubler circuit, a shift register clock driver, a 906-stage CCD analog shift register, and a resampling output amplifier.

The MN3885S drives and samples the 906-stage analog shift register using a redoubled version of the supplied clock signal with a frequency 7.16 MHz of twice the NTSC color signal subcarrier frequency, and after adding in the attached filter delay, produces a delay of 1 H (the horizontal scan period).
