Pin Description
Crystal connection (REF frequency). Connect to a parallel resonant crystal or an
input clock.
No connect. Do not connect anything to this pin.
Connect to 3.3 V or 5 V.
No connect. Do not connect anything to this pin.
Connect to ground.
Output clock 2, determined by F0 - F1. Can be reference, REF/2, CLK1/2 , or off.
No connect. Do not connect anything to this pin.
Serial clock. See timing diagram.
Strobe to load data. See timing diagram.
No connect. Do not connect anything to this pin.
Output clock 1, determined by R0 - R6, V0 - V8, S0 - S2, and input frequency.
Data input. Serial input for three words which set the output clock(s).
Powers down entire chip, tri states CLK1 and CLK2 outputs when low. Internal
pull-up.
No connect. Do not connect anything to this pin.
No connect. Do not connect anything to this pin.
