GENERAL DESCRIPTION
This user guide describes how to set up and use the evaluation
board for the ADCLK905/ADCLK907/ADCLK925. The same
printed circuit board (PCB) is used to evaluate all three devices.
The ADCLK905/ADCLK907/ADCLK925 data sheet should be
used in conjunction with this user guide.
The data sheet contains full technical details about the spec-
ifications and operation of these devices.
The ADCLK905/ADCLK907/ADCLK925 clock buffers are
very fast, making it important to use adequate high bandwidth
instruments to evaluate them. To that end, the evaluation board
is fabricated using a high quality dielectric material between
layers to maintain high signal integrity. Transmission line paths
are kept as close to 50 Ω as possible.

RECOMMENDED BOARD SETUP
The recommended setup for the evaluation board is shown
in Figure 2. Note that there is no LVPECL output termination
on the evaluation board. LVPECL termination is accomplished
via the 50 Ω input of the oscilloscope. To meet the standard
LVPECL output termination (V
CC
− 2 V into 50 Ω), V
CC
is set
to 2 V and V
EE
is set to −1.3 V. This also meets the requirement
for V
CC
− V
EE
= 3.3 V.
