User's Manual

Description

This document describes the NB7L14M evaluation board
and the appropriate lab test setups. It should be used in
conjunction with the NB7L14M data sheet which contains
full technical details on the device specifications and
operation.
The evaluation board is designed to facilitate a quick
evaluation of the NB7L14M GigaCommt clock/data
receiver/driver/translator device. The NB7L14M is
designed to support the distribution of clock/data signals at
high operating frequencies and produces four equal
differential clock/data outputs from a single input
clock/data. The Current Mode Logic (CML) output ensures
minimal noise and fast switching edges.
The evaluation board is implemented in two layers for
higher performance.
Board Lay−up
The board is implemented in two layers and provides a
high bandwidth 50 W controlled impedance environment for
higher performance. The first layer or primary trace layer is
5 mils thick Rogers RO6002 material, which is engineered

to have equal electrical length on all signal traces from the
NB7L14M device to the sense output. The second layer is
32 mils thick copper ground plane.
