TVWIN
The PLL unlocks if the reference signal is lost for more than the time defined in the
TVWIN register. During the TSI GAP (See TSI GAP Mode) the PLL and the TVWIN are
frozen.
The TVWIN time is the time that DigRX should stay locked without incoming signal
edges detected. The time resolution is T/16.
TVWIN is calculated as follows:
CV is the number of code violations in a block.
This calculation is done by IAF TDA523x Configuration Tool, if the number of CV’s
is entered.
