Output Synchronization Signals Polarity
INV_LLC_POL, IO Map, Address 0x06, [0]
The polarity of the pixel clock provided by the
inversion affects only the LLC output pin. The other output pins are not affected by INV_LLC_POL.
Changing the polarity of the LLC clock output may be necessary in order to meet the setup and hold time expectations of the downstream
devices processing the output data of the ADV7610. It is expected that these parameters must be matched regardless of the type of video
data that is transmitted. Therefore, INV_LLC_POL is designed to be mode independent.
INV_LLC_POL, IO, Address 0x06[0]
A control to select the polarity of the LLC.
Function
INV_LLC_POL
0 (default)
1
The output synchronization signals HS, VS/FIELD/ALSB, and DE can be inverted using the following control bits:
•
INV_HS_POL
•
INV_VS_POL
•
INV_F_POL
INV_HS_POL, IO, Address 0x06[1]
A control to select the polarity of the HS signal.
Function
INV_HS_POL
0 (default)
1
INV_VS_POL, IO, Address 0x06[2]
A control to select the polarity of the VS/FIELD/ALSB signal.
Function
INV_VS_POL
0 (default)
1
INV_F_POL, IO, Address 0x06[3]
A control to select the polarity of the DE signal.
Function
INV_F_POL
0 (default)
