CCD Delay Line Series
MN38663S
NTSC-Compatible CCD Video Signal Delay Element
Overview
The MN38663S is a CCD signal delay element for video
signal processing applications.
It contains such components as a threefold-frequency
circuit, a shift register clock driver, charge I/O blocks,
two CCD analog shift registers switchable between 680.5
and 605 stages, a clamp bias circuit, resampling output
amplifiers, and booster circuits.
When the switch input is "L" level, the MN38663S
samples the input using the supplied clock signal with a
frequency of three times the NTSC color signal subcarrier
frequency (3.579545 MHz) and, after adding in the attached filter delay, produces independent delays of 1 H
(the horizontal scan period) each for the two lines. When
the switch input is "H" level, the MN38663S disables the
threefold-frequency circuit and samples the input with
the image sensor drive frequency (9.545454 MHz) for
the camera's 510 horizontal pixels and, after adding in
the attached filter delay, produces independent delays of
1 H (the horizontal scan period) each for the two lines.
Features
Single 4.4 V power supply
Choice of camera and VCR modes, so that both the
camera and VCR portions of a video camera with 510
horizontal pixels can use the same MN38663S for signal processing
