Application Note
AN 97085
2.3.2
CVBS Subclick Connector
This is the output for the CVBS signal that passed the 5MHz LOWPASS FILTER and the JP14 (CVBS_out). This
jumper selects the CVBS output (CVBS0 or optionally CVBS1,2 at Y/C lines). A simultaneous load at this conne-
xctor and the SCART connector should be avoided.
2.3.3
SCART Connector
Fig.2 Output Connector
The figure above shows the analog output circuit with Subclick- and SCART- connector. The main CVBS line
should not be switched to both Subclick and SCART (CVBS output or CSYNC) at the same time. The SAA7128/
29 and SAA7138/39 offer additional CVBS outputs on Y and C pins as option (JP14). To enable RGB input to a
SCART TV plug, close JP16. In this case JP17 must be in position ’RGB’
SAA7120/21: This device provides no other signals than CVBS and Y/C one time so the jumper configuration is
JP14 = CVBS0 and JP17 = Y/C.
SAA7126/27: This device provides CVBS and Y/C or RGB signals at the respective connectors. For Y/C output
JP31 and JP32 must be closed.
