4.1.1
An analog inset CVBS signal can be fed to the inputs CVBS1-3 of SDA 9589X/SDA
9489X. Each of these sources is selectable via I
can be used as separate Y/C inputs. At SDA 9589X YUV sources can be connected to
CVBS1, CVBS2 and CVBS3 provided YUV operation being enabled (YUVSEL). Using
an external switch SDA 9589X can operate in applications with both YUV and CVBS
signals.
4.1.2
All signal are clamped and AD-converted with an amplitude resolution of 8bit. CVBS and
Y signals are clamped to the sync bottom whereas U/V and C signals are clamped to
their mid-level during blanking.
