Function
1
VDD_DIG
P
Voltage supply for digital functions. Connect to 1.8–3.3 V. Part of internal
core VDD voltage. Must be connected to same voltage as VDDA and
VDD_XTAL.
2
CLKIN_2
I
These pins accept both differential and single-ended clock signals. Refer
to Section
for input termination options. These pins are
high-impedance and must be terminated externally. If both the CLKIN_2
and CLKIN_2b inputs are un-used and powered down, then both inputs can
be left floating. ClockBuilder Pro will power down an input that is set as
"Unused".

CLKIN_2b
I
4
VDD_XTAL
P
Voltage supply for crystal oscillator. Connect to 1.8–3.3 V. Part of internal
core VDD voltage. Must be connected to same voltage as VDDA and
VDD_DIG."
