Active low to stop differential output buffers, This is internal 120K pull up. Latched input at power up to selecting PLL Band Width 0=HIGH, 1=LOW, This is internal 120K pull up. Deciding the reference current for the Differential clock pairs. The pin was connected to the precision resistor tied to ground to decide the appropriate current; 475 ohm is the standard value for 0.7V differential clock output. Latched output, transitions high when PLL lock is achieved. 1= PLL mode, 0=NORMAL buffer mode.
