Preliminary Data Sheet

General Description
SDA 9488X 'PIP IV Basic' and SDA 9588X
'OCTOPUS' belong to a new generation of cost-
effective PiP processors that combine high-quality
digital PIP signal processing, digital multistandard
color decoding and AD/DA conversion on a single chip.
Both devices are equipped with CVBS and Y/C input
interfaces. In addition the SDA 9588X is also able to
process YUV input signals for displaying high-quality
video signals e.g. coming from a DVD source.

Figure 0-1

Picture-In-Picture

The integrated digital color decoder is able to decode all analog TV standards (PAL,
NTSC and SECAM) and detects the standard automatically. Therefore the IC is suited
for world-wide use.
A picture reduction from 1/9 to 1/81 of original size selectable in fine steps is possible.
The transfer functions of the decimation filters are optimally matched to the selected
picture size reduction and can furthermore be adjusted to the viewer's requirements by
a selectable peaking. A maximum of 216 luminance and 2x54 chrominance pixels per
line are stored in the memory.
