Output to the delay line and input for the delay line reflected signal.
Outputs the signal that has passed through 1H interpolation. Aperture
correction is performed by inserting an aperture correction delay line
(with an impedance of about 1 k
) at this output. Since a 1 k
resistor is built in to this pin's internal circuit, the DL reflected signal is
created at about 1/2 the level of the original signal. This signal is
combined with the original signal and the combination is input to the
aperture correction circuit.
Delay line delayed signal input. This pin inputs the signal that has
passed through the aperture correction delay line to the aperture
correction circuit. The combined signal consisting of the original
signal and the reflected signal is subtracted from the delay line signal
(pin 27), and the aperture whisker components are created by
amplifying that difference signal. See the description of pins 19 and
20 for details on whisker component control.
The aperture clipped whisker components are added to the original
signal at a fixed ratio and output from this pin. The original signal
gain is about 0 dB.
The aperture corrected signal is input to this pin through a coupling
capacitor. OPB clamping is applied at the input stage, clamping at
about 1.8 V with the timing of the clamp pulse signal input to pin 40.
Ground for the 75
driver system.
Video signal output. A signal that has sync added at pin 37 and has
been amplified is output through the driver circuit. When output is to
a unit that has a 75
load, the 140 IRE = about 1.9 V output signal
can be converted to a 140 IRE = about 1.0 V signal by inserting a
68
resistor.
