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).

Figure 5-1 SDA 9589X application with insertion in front of the featurebox
The output of two ’SOPHISTICUS’ 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 the SDA 9589X/SDA 9489X directly to the RGB input of the RGB processor
is possible as well. One picture is generated from SDA 9589X/SDA 9489X device, the
other one from the featurebox. This cheap implementation preserves the chroma of inset
channel at its full bandwidth, although frame mode is only possible for PiP pictures
