VDD
Supply
Supply.
The device operates from a 1.8, 2.5, or 3.3 V supply. Bypass
capacitors should be associated with the following VDD pins:
5
0.1 F
10
0.1 F
32
0.1 F
A 1.0 F should be placed as close to device as is practical.
6, 8,19,
20, 31
GND
Supply
Ground.
Must be connected to system ground. Minimize the ground
path impedance for optimal performance of this device.

AUTOSEL
I
3-Level
Manual/Automatic Clock Selection.
Three level input that selects the method of input clock
selection to be used.
L = Manual.
M = Automatic non-revertive.
H = Automatic revertive.
The pin has a weak pull-up and weak pull-down and
defaults to M.
Some designs may require an external resistor voltage
divider when driven by an active device that will tri-state.
12
13
CKIN2+
CKIN2–
IMulti
Clock Input 2.
Differential input clock. This input can also be driven with a
single-ended signal. Input frequency selected from a table
of values. The same frequency must be applied to CKIN1
and CKIN2.
14
DBL2_BY
I
3-Level
Output 2 Disable/Bypass Mode Control.
Controls enable of CKOUT2 divider/output buffer path and
PLL bypass mode.
L = CKOUT2 enabled.
M = CKOUT2 disabled.
H = Bypass mode with CKOUT2 enabled.
CMOS outputs do not support Bypass Mode.
The pin has a weak pull-up and weak pull-down and
defaults to M.
Some designs may require an external resistor voltage
divider when driven by an active device that will tri-state.
16
17
CKIN1+
CKIN1–
IMulti
Clock Input 1.
Differential input clock. This input can also be driven with a
single-ended signal. Input frequency selected from a table
of values. The same frequency must be applied to CKIN1
and CKIN2.
