To cover the range from 10 to 18 MHz (0 to 70°C) and 8
to 16 MHz (-40 to 85°C), select address 01 to generate
2x your desired output frequency, then configure CLK2
to generate CLK1/2.

Pin Description
Reference divider word input pins determined by user. Forms a binary number
from 0 to 127. Internal pull-up resistor.
Selects CLK2 function to output a SYNC signal or a divide by 2 of CLK1 based
on the table above. Internal pull-up resistor.
Select pins for output divider determined by user. See table above. Internal
pull-up resistor.
Connect to VDD.
Reference clock input.
Feedback clock input.
Connect to ground.
CLK2 Output Enable. CLK2 tri-stated when low. Internal pull-up resistor.
Clock output drive strength doubled when high. Internal pull-up resistor.
Feedback divider word input pins determined by user. Forms a binary number
from 0 to 127. Internal pull-up resistor.
Power Down. Active low. Turns off entire chip when low, both clock outputs are
tri-stated. Internal pull-up resistor.
Output clock 2. Can be SYNC output or a low skew divide by 2 of CLK1.
Output clock 1.
