... I.6 - Synchro Identification Status The MCU can choose via the I priority thanks to the system identification status provided by the TDA9110. The extracted Vertical synchro pulse is available when this identification status has been received and when the 12V is supplied. Even in Power managementmode the IC is able to inform the MCU that synchrosignals were detected due to its 5V supply ...

... TDA9110 OPERATING DESCRIPTION (continued) Of course, when the choice is done, we can refresh the synchro detectionsand verify that the extracted Vsync is present and that no synchro type change have occured. Synchro processor is also giving synchro polarity information. I status TheIC can inform the MCUabout the 1st Horizontal PLL or Vertical section status (locked or not), and about the Xray protection (activated or not) ...

... From A Phase NOR1 Comparator The TDA9110 also includes a Lock/Unlock identifi- cation block which senses in real time whether the the PLL1 is locked or not on the incominghorizontal synchro signal. The resulting information is avail- able on Hlockout (see Synchro Processor). The block function is described in Figure 12. ...

... This protection is reset either (see Figure 16). II.6 - Horizontal and Vertical Dynamic Focus The TDA9110 delivers a horizontalparabola which is added on a vertical parabola waveform on Pin 15. This horizontal parabola comes from a saw- tooth. The phase advance versus Horizontal fly- back middle is kept constant for each frequency (about 860ns) ...
