CP and HDMI Simultaneous Mode

The ADV7604 can be configured to be in either simultaneous mode or non simultaneous mode, as
follows:
• Non simultaneous mode
In this mode, the ADV7604 will process either analog or HDMI/DVI inputs. The HDMI
section is disabled when the ADV7604 is configured to process analog inputs. The ADCs are
powered down when the part is configured to process HDMI/DVI inputs in HDMI mode.
• Simultaneous mode
In this mode, specific subsections of the HDMI block remain enabled when the ADV7604 is
programmed to process analog inputs through the CP core. Simultaneous mode keeps the
HDCP engine and the EDID/Repeater controller active, allowing an upstream transmitter to
authenticate the ADV7604 even when the latter is in analog mode. Keeping the HDCP engine
active allows for fast switching from analog mode to HDMI mode, as the transmitter will
have already authenticated the ADV7604 when the latter is switched into HDMI mode.
Notes:
• Simultaneous mode only affects the ADV7604 when the latter is programmed to process
analog inputs through the CP core.
• Simultaneous mode has no effect when the part is programmed in HDMI mode as the full
HDMI section is enabled in this mode.
• The ADCs are powered down automatically in HDMI mode.
