Functional Description
2.1
Analog Processing and A/D Converters
Figure 21 shows a functional diagram of the analog processors and A/D converters, which provide the analog
interface to all video inputs. It accepts up to 10 inputs and performs source selection, video clamping, video
amplification, A/D conversion, and gain and offset adjustments to center the digitized video signal. The
TVP5147M1 supports one analog video output for the selected analog input video.

2.1.1 Video Input Switch Control
The TVP5147M1 decoder has two analog channels that accept up to 10 video inputs. The user can configure
the internal analog video switches via the I2C interface. The 10 analog video inputs can be used for different
input configurations, some of which are:
