Monolithic Linear IC
LA7191N
Global VHS-format VCR
Video Signal Processor
Overview
The LA7191N is a multi-format, single-chip video signal
processing IC that supports TV systems around the world.
.Features
Compatible with TV systems around the world (NTSC/
. PAL/MESECAM/4.43 -NTSC/PAL-M/PAL-N).
All filters on chip, except for PB-LPF for chroma (cutoff
frequency requires no adjustment).
. No adjustment of YNR and DOC levels.
. Double high-pass noise canceller on chip.
. Linear phase-type picture control on chip.
. fsc output can be used as clock for OSD IC.
. DCC circuit on chip.
. Pilot burst erasure circuit on chip.
. High-speed AFC circuit on chip.
. Switching noise canceller on chip.
. Smallest package in the industry.
. Few components needed.
. 2fsc output.
. I/O pin for CNR insertion added.
. YNR/LNC switching possible.

VIN = standard color bar signal (1 Vp-p),
input +6 dB chroma signal level only,
measure T15A burst level, and calculate ratio
with VOR-15
VIN = standard color bar signal (1 Vp-p),
input –6 dB chroma signal level only,
measure T15A burst level, and calculate ratio
with VOR-15
VIN = standard color bar signal (1 Vp-p),
lower the chroma signal, and measure the
input burst level at the point where output at
T15A ceases, and calculate the ratio with the
standard input level
VOACCK T37A T15A Use a spectrum analyzer to measure the
output level at T15A in the killer state
described previously; ratio with VOR-15
VACCK-OFF T4A T34A Starting from the killer state described
previously, gradually raise the input chroma
level and measure the input burst level when
output is generated at T15A and calculate the
ratio with the standard input level

Input a 50% white signal overlapped with a
4.4336 MHz, 300 mVp-p continuous wave.
After confirming that there is output at T15A,
increase the frequency of the CW until the
output at T15A stops, and then gradually
reduce the frequency until output appears
again at T15A; that CW frequency is f1.
∆fAPC1 = f1 – 4433619 (Hz)
In the same manner, reduce the frequency of
the CW until the output at T15A stops, and
then gradually increase the frequency until
output appears again at T15A; that CW
frequency is f2.
∆fAPC2 = f2 – 4433619 (Hz)
Measure waveforms at T32 and T36 when a
standard color bar signal (1 Vp-p) is input.
