HA11569FS

PIP Chroma H/V Signal Processing LSI

(NTSC)

Rev. 2

Sep 1993

The HA11569FS is a main/sub Picture chroma and

H/V signal processing LSI with built-in video

switch for NTSC suited PIP systems. The

HA11569FS implements on a single chip the PIP

analog signal processing block which had

previously been formed by three LSIs, the

HA11525MP, the HA11532MP, and the

HA118088NT. Furthermore, the HA11569FS has

been designed to also handle Y and C inputs (S

input).

Features

•

An NTSC PIP system can be constructed from

this and two other (the HD49412 and the

HM53461) ICs.

•

As compared with earlier PIP chip sets, a large

reduction in the number of external

components can be achieved.

•

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.

A PIP system can be constructed from this IC and

two other ICs (the HD49412 and the HM53461),

that is, from a total of 3 ICs.
