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 also be placed as close to device as is prac-
tical.

External Crystal or Reference Clock.
External crystal should be connected to these pins to use
internal oscillator based reference. Crystal or reference clock
selection is set by the XTAL/CLOCK pin.

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 selec-
tion to be used.
L = Manual
M = Automatic non-revertive
H = Automatic revertive
This 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.
11
XTAL/CLOCK
I
3-Level
External Crystal or Reference Clock Rate.
Three level input that selects the type and rate of external
crystal or reference clock to be applied to the XA/XB port.
This pin has both a weak pull-up and a weak pull-down and
defaults to M.
L = Crystal
M = Clock (Default)
H = Reserved
Some designs may require an external resistor voltage
divider when driven by an active device that will tri-state.

CKIN2+
CKIN2–
I
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.
