Board User's Manual

Introduction

The NB7L1008 is a high performance differential
1:8 Clock/Data fanout buffer that operates up to
12 Gbps/7 GHz with a 2.5 V or 3.3 V power supply.
ON Semiconductor has developed a "universal" QFN−32
evaluation board and configured it for the NB7L1008. This
evaluation board was designed to provide a flexible and
convenient platform to quickly evaluate, characterize and
verify the operation of the NB7L1008.
This evaluation board manual contains:
•
Information on the NB7L1008 Evaluation Board
•
Test and Measurement Setup Procedures
This manual should be used in conjunction with the device
datasheet, which contains full technical details on the device
specifications and operation.

Board Layout

The NB7L1008 Evaluation Board provides a high
bandwidth, 50-W controlled impedance environment and is
implemented in one layer.

If the input signals to the NB7L1008 require termination,
internal 50-W resistors are provided via the VT pin and
grounded using a SMA grounding plug then and should be
stimulated with the appropriate voltage levels.
