Figure 6: Synchronization Path - Analog Devices Advantiv ADV7604 Hardware Manual

• Section 5: The CP core outputs the following signals to the output formatter section:
HS with negative polarity
VS with negative polarity
DE with negative polarity
Note that the CP core generates the DE signal for analog input. In HDMI mode, the
CP core regenerates the DE signal from the DE output by the HDMI receiver section.
• Section 6: The output formatter outputs the synchronization signal through the pins as
follows:
HS with positive polarity only if INV_HS_POL is set to 1
VS with positive polarity only if INV_VS_POL is set to 1
DE with positive polarity only if INV_F_POL is set to 1
