Dynamic Delay Adjustment
The Dynamic Delay Adjustment is controlled by the DDAMODE input. When the DDAMODE input is set to “1”, the
delay control is handled through the inputs, DDAIZR, DDAILAG and DDAIDEL(2:0). For this mode, the attribute
“DELAY_CNTL” must be set to “DYNAMIC”. Table 11-3 shows the delay adjustment values based on the attri-
bute/input settings.
In this mode, the PLL may come out of lock due to the abrupt change of phase. RST must be asserted to re-lock
the PLL. Upon de-assertion of RST, the PLL will start the lock-in process and will take the t
the PLL lock.
