DOFF
Input
PLL turn off
active LOW. Connecting this pin to ground turns off the PLL inside the device. The timing
in the PLL turned off operation differs from those listed in this data sheet. For normal operation, this pin
can be connected to a pull up through a 10 K
or less pull-up resistor. The device behaves in DDR I
mode when the PLL is turned off. In this mode, the device can be operated at a frequency of up to 167 MHz
with DDR I timing.
