HA11579
P-I-P Analog
Signal Processing LSI (NTSC)
Rev.1
Sep. 1993
The HA11579 is a main/sub Picture analog signal
Features
processing LSI for NTSC suited PIP systems. The
HA11579 has built-in the Band Pass Filter BPF and
Low Pass Filter LPF with automatically adjustment
function, and can reduce external components.
Furthermore, the HA11579 has been designed to
also handle Y and C inputs (S input).
•
An NTSC PIP system can be constructed from
this and two other (the HD49420FS and the
HM53461) ICs.
As compared with earlier PIP chip sets, a large
reduction in the number of external components
can be achieved.
•
A PIP system can be constructed from this IC and
two other ICs (the HD49420FS and the HM53461),
that is, from a total of 3 ICs.
•
•
Can handle S inputs
A black level compensation circuit is built into
the sub-picture processing circuit, and such
problems as black lifting are eliminated.
A color signal level compensation circuit is built
into the sub-picture processing circuit, and the
sub-picture color signal level is always stable.
