Application Examples
The following two figures show 100/120Hz applications with the Micronas Featurebox
SDA 9400/01. As the chip supports two I2C addresses and owns a RGB switch dual-PiP
applications are easy to implement. The arrangement for best possible performance is
shown in the fig. (5-1).

The output of two âOCTOPUSâ are connected to the YUV (or RGB) input of the video
processor of the main channel. Due to the 4:2:2 processing within the SDA 9400 the
inset picture remains brilliant.

Connecting of a SDA 9588X directly to the RGB input of the RGB processor is possible
as well. One picture is generated from SDA 9588X device, the other one from the
featurebox. This cheap implementation preserves the chroma of inset channel at its full
bandwidth, although only field mode is possible for PiP picture. The output of an OSD/
Text processor may be fed to the RGB switch of the SDA 9588X.
