EXT_CLK
Input
External clock feed-through: 0 to 200 MHz
25
STOP
Input
Internal pull-down resistor1
Logic 1 stops clock outputs.
Use Logic 0 for normal operation.

XTAL_1 / REF_IN
Input
External crystal connection. Also accepts
LVCMOS/LVTTL compatible clock source.
28
XTAL_2
Input
External crystal connection. Leave unconnected
when driving pin 27 with external clock reference.
34, 35, 36
DNC
Do Not Connect.
