Figure 106: System Delay for External Clock and Clamp Mode
• Regeneration mode
The external clamp pulse fed into the ADV7604 is regenerated inside the ADV7604, which
enables the user to control the clamp pulse position control of the analog voltage clamp and
also the digital fine clamp. This regeneration mode is useful for the user to compensate for
the system delay of clamp control within the ADV7604.
• Nonregeneration mode (direct clamp control)
The external clamp pulse fed into the ADV7604 directly controls the analog voltage clamp
block with no internal position control. The user back end system needs to control the
accurate clamp control positioning, taking system delay into consideration.
