PANASONIC MN3814S

CCD Delay Line Series
MN3814, MN3814S
NTSC CCD Video Signal Delay Elements
Overview
The MN3814 and MN3814S are 4 fSC CMOS CCD signal
delay elements whose wide bandwidth and low noise make
them ideal for video signal processing applications.
They contain such components as a shift register clock
driver, 906-stage CCD analog shift register, and resampling
output amplifier.
They sample the input using the supplied clock signal with
a frequency of 14.32 MHz, four times the NTSC color signal
subcarrier frequency, and after adding in the attached filter
delay, produce independent delays of 1 H (the horizontal scan
period).
