DEMO KIT CONTENTS
This document describes designs available on the development kit CDROM for the 434 and 915 MHz ISM Repeater Demo.
Also covered are the diagrams for both LCD and non-LCD variants. For further details, please refer to
www.integration.com/
evaluation_kits.php or the IA ISM-DKxx CDROM.
IA ISM-UGRP contains the following items:
• Push Button Demo transmitter board
• Two Push Button Demo receiver boards
• Repeater Demo board
• User Guide
1
This document is designed to provide as the user guide to all variants of the Repeater Demo. Photographs may differ
depending on version. The photograph above is the 434 MHz LCD version.
OVERVIEW
The demo’s main objective is to show the IA4420’s capability to monitor multiple frequencies, receive data from an FSK
transmitter, and then re-transmit this data on an another arbitrary frequency to another receiver or transceiver. This
demonstration is designed to show the IA4420 acting as a repeater node.
The Repeater Demo has three main components: the IA4420, which is the system radio, a C8051F311 type 8051
microcontroller, which controls the application, and a 2 line 16 character LCD, which informs the user of the repeater status
(Note)
.
The current version of the Repeater Demo is equipped with a 50 Ohm SMA connector for the antenna.

OVERVIEW

The demo uses the developer-friendly features of the IA4420 device. In receive mode the microcontroller reads the received
bytes from the IA4420’s FIFO, and transmits them through the TX latch. This approach dramatically reduces the load on the
micro, because the microcontroller doesn’t have to monitor every bit, only the bytes. This means the timing constraints in
an application can be reduced at least by a factor of eight for both the transmitting and the receiving sides. See the
PROCESSOR ACTIVITY lines on Figure 2, as demonstrated for both the ‘Traditional’ transceiver mode and the Integration
‘FIFO’ mode.

DESCRIPTION
The frequency configuration of this demo is as follows:
• One of the Push Button Demo receivers is set to a different frequency than that of the Push Button transmitter.
The other receiver is paired with the frequency of the transmitter.
• The Repeater demo receiving frequency is set to the frequency of the Push Button demo transmitter.
The Repeater demo transmitting frequency is set to the non-paired Push Button demo receiver’s frequency
.

Fig. 3 Repeater Demo Arrangement
After power on, the Repeater Demo continually looks for a valid packet on the receiving frequency. This happens when one
button has been pressed on the Push Button Demo transmitter. At this moment the LED will light up on the paired Push
Button receiver board. After the Repeater Demo (transceiver board) properly receives this packet, it will forward the packet
on its transmitting frequency. At that time, the LED will light up on the non-paired Push Button receiver board, if both of the
Push Button Transmitter and Push Button Receiver are in the range of the Repeater Demo. It should be noted that the
transceiver in this demo adds a small time delay between receiving and transmitting. This is done to prove the transmitter
is not talking directly to the receiver. Depending on the button pressed, a different time delay is implemented.
A packet is valid if it contains the preamble bytes (0xAA), the synchron pattern (0x2DD4), and the data, which corresponds
to the Push Button Demo data structure.
It can be shown that the paired Push Button demo is working alone, but if the Repeater demo is operating, then both the
Push Button Receivers will work, and the RF communication range is significantly bigger than without the Repeater Demo.
