SDA9489X
ANALOG-TO-DIGITAL CONVERTER LNEAR SUBSYSTEM

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.
Figure 5-2 SDA 9589X application with insertion behind the featurebox
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
smaller than 1/9. The output of an OSD/Text processor may be fed to the RGB switch of the SDA 9589X/SDA 9489X.
