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.
