Getting Started
Hardware Requirements
1. A personal computer with a minimum Pentium II, 300
MHz, 32MB RAM, 5MB free disk space, v1.1 USB port
interface, and running Windows 98, ME, or 2000
operating systems. Windows NT does not support the
USB interface and should not be used.
2. A 5Vdc power supply capable of supporting the
evaluation CCA by sourcing 2.0 amps.
Software Installation
1. In order to supply the latest software and documentation
at the time of purchase, the software media is only
available from the Intersil website at www.intersil.com.
Please search on the device or evaluation board number,
as the software and all other related documentation for
the evaluation kit is downloadable from the website.
2. Download the ISL5239.exe file to the host computer ’s
root directory. (C:)
3. Execute the ‘ISL5239.exe’ installation program from the
distribution media. This program will create folder
ISL5239 and install the required files.
Hardware Description
The ISL5239 eval. board allows demonstration of the
ISL5239 device functions and can serve as a reference for
development and verification of customer prototypes. In
addition, the eval. board has interfaces that allow
interconnection with other Intersil eval. boards and
commercial equipment, as depicted in the block diagram.
These interfaces facilitate the generation and observation of
pre-distorted signals in a lab environment during application
development to provide for PA pre-distortion algorithm
development and implementation.
The device input capture memory and output capture
memory provides for demonstration of the ISL5239 signal
processing modes. It can be used as a device learning tool
and as part of lab prototype set-up for experimental
development of linearization systems. It is a tool for the early
development of control set-ups, algorithms, thermal memory
effect compensation, and system performance estimates.
Board Components
The evaluation board consists of four major components as
depicted in the block diagram:
1. ISL5239 U16: This is the Pre-Distortion Linearizer device.
This device is clocked by the onboard U6 oscillator or an
external reference supplied through J2 to drive the U5
programmable skew clock buffer.
2. USB Interface U19: This is a complete USB interface to
provide for programming and controlling the ISL5239
device. The USB also allows for direct configuration of
the on-board CPLD and FPGA devices.
3. CPLD U2. The primary function of the CPLD is
input/output signal conditioning to provide for digital
2
output from the ISL5239 IOUT<17:0> and QOUT<17:0>
output busses. The CPLD also provides several
operational modes to control the FBCLK and FB<19:0>
inputs.
4. FPGA U1: The FPGA’s main function is to provide a user
programmable hardware implementation for temperature
compensation. A typical implementation is pre-loaded
into the board with the details available in the device
verilog.
USB Registers
The USB is configured with 128 registers which contain the
control information for the CCA. These registers can be
accessed from the evaluation software using the console
commands “read” and “write” or the script commands
“PDP.read” and “PDP.write.” For more details refer to the
Software Description’ section.
Hardware Configuration
Verify the following default jumper configurations.
1. J4 in position 2-3, J7 5-6 and J7 7-8 jumpered.
2. Connect the 5 volt power supply to the evaluation board
connector J13 utilizing the supplied power cable. Ensure
the power supply can source 2.0 amps regulated at
5Vdc±5%.
WARNING: Ensure care is utilized to prevent the appli-
cation of reverse polarity power to the CCA.
3. Connect the supplied USB cable from the PC’s USB port
to the evaluation board’s J12 connector.
Software Description
The evaluation software provides a Graphical User Interface
(GUI) that allows full control over all operational modes of
the ISL5239 evaluation board and the ISL5239 IC. The
software also implements functions for loading LUT patterns
into device memory and for supporting capture memory
loading and reading operations. Control of the on-board
CPLD and FPGA can be accomplished via the GUI.
Controlling the board can be done by using the forms
provided in the software, by using the active command
window to execute commands pertaining to accessing
registers directly in a peek/poke manner, or by running
configuration files. The software contains eight forms, each
controlling a specific part of the board.
The software also has pull-down menus through which the
user can execute various commands. These commands
include running configurations files, controlling the stimulus,
loading the capture memories, and writing to the LUT’s in the
device. These functions are discussed in more details in the
following sections.
Running the Software
1. Turn on the power supply to the board and verify less
than 1.5A is being drawn.
