LA71525M
Monolithic Linear IC
LA71525M
Video/audio signal processor for VHS VCRs
(single chip for Y/C/A)
Overview
The LA71525M is a video/audio signal processor IC
for VHS VCRs. It handles recording and playback of
PAL/GBI, MESECAM, and 4.43 NTSC signals.
NTSC software tapes can be converted to PAL for
monitoring, and the IC realizes high picture and sound
quality. The IC requires no adjustments and minimizes
the peripheral component count, making it possible to
implement efficient signal handling at low cost.

T14A Input signal: 50% white signal superimposed with
4.4336 MHz 300 mVp-p CW. After checking that T14A
output is on, CW frequency is raised until T14A output
goes off. Frequency then is gradually reduced.
CW frequency when T14A output goes on: f1
T14A Same as above, CW frequency is lowered until T14A
output goes off. Then frequency is gradually raised.
CW frequency when T14A output goes on: f2
T51 300 mVp-p, 15.6 kHz pulse train with 5 µs pulse width
