Power supply jack
J18
Connect to 1.8V, 2.5V, or 3.3V for the output voltage of
the device
1
Ground jack
J19
If J18 & J17are used for power supply, this is the return
power
2

CLKIN/CLKINB
A differential clock can be connected as source for the
device
5
(cont.)
Single-ended clock input
CLKINB
A Single-ended clock can be connected as source for
the device using CLKINB only
6
Crystal, 25 MHz
Y1
This crystal is used as a reference source for the clock
signal

This can be a differential pair, or two single-ended
outputs. By default, it’s a LPHCSL differential output.
8
Differential output
DIFF_C0/T0
This can be a differential pair, or two single-ended
outputs. By default, it’s a LPHCSL differential output.
9
Single-ended output
SE_1
This is the single-ended output. By default it’s an
LVCMOS single-ended output
