EVALUATION BOARD MANUAL

INTRODUCTION

This manual should be used in conjunction with the device

data sheet, which contains full technical details on the device

specifications and operation.

ON Semiconductor has developed an evaluation board for

the devices in 32-lead LQFP package. These evaluation

boards are offered as a convenience for the customers

interested in performing their own engineering assessment

on the general performance of the 32-lead LQFP device

samples. The board provides a high bandwidth 50 W

controlled impedance environment. Figures 1 and 2 show

the top and bottom view of the evaluation board, which can

be configured in several different ways, depending on

device under test (see Table 1. Configuration List).

Board Lay-Up

The 32-lead LQFP evaluation board is implemented in

four layers with split (dual) power supplies (see Figure 3.

Evaluation Board Lay-Up). For standard ECL lab setup and

test, a split (dual) power supply is essential to enable the 50

W internal impedance in the oscilloscope as a termination for

ECL devices. The first layer or primary trace layer is 0.008″

thick Rogers RO4003 material, which is designed to have

equal electrical length on all signal traces from the device

under the test (DUT) to the sense output. The second layer

is the 1.0 oz copper ground. The FR4 dielectric material is

placed between second and third layer and between third and

fourth layer. The third layer is the power plane (V & V

)

• Bill of Materials

and a portion of this layer is a ground plane. The fourth layer

is the secondary trace layer.
