3-Level
Signal Format Select.
Three level inputs that select the output signal format (com-
mon mode voltage and differential swing) for both CKOUT1
and CKOUT2. Valid settings include LVPECL, LVDS, and
CML. Also includes selections for CMOS mode, tristate
mode, and tristate/sleep mode.
CMOS outputs do not support Bypass Mode.
These pins have both weak pull-ups and weak pull-downs
and default to M.
Some designs may require an external resistor voltage
divider when driven by an active device that will tri-state.

CKOUT2–
CKOUT2+
OMulti
Clock Output 2.
Differential output clock with a frequency selected from a
table of values. Output signal format is selected by SFOUT
pins. Output is differential for LVPECL, LVDS, and CML
compatible modes. For CMOS format, both output pins drive
identical single-ended clock outputs.

OMulti
Clock Output 1.
Differential output clock with a frequency selected from a
table of values. Output signal format is selected by SFOUT
pins. Output is differential for LVPECL, LVDS, and CML
compatible modes. For CMOS format, both output pins drive
identical single-ended clock outputs.

Supply
Ground Pad.
The ground pad must provide a low thermal and electrical
impedance to a ground plane.
