No Connect Pin
No internal bonding. This pin should be open or connected to the ground.
Output 1 Pin for Loop Filter of PLL Circuit
A8 VCOC1
O This pin should be connected to DVSS with a resistor (10kΩ) and a capacitor
(4.7nF) in series.
Output 2 Pin for Loop Filter of PLL Circuit
B8 VCOC2
O This pin should be connected to DVSS with a resistor (10kΩ) and a capacitor
(4.7nF) in series.
Note: All input pins except analog input pins should not be left floating (XTI/MCKI, PLL0, SDATAOUT, SYNC,
RESETN, PLL1 and ADEXE pins).
