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 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. 1 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.

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.

Process Activity in FIFO Mode when Compared to a Traditional Mode of Operation 3 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 .

Push Button Demo receiver on F2 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. 4 Demo Unit TABLE OF CONTENTS Radio Hardware Stage 1 – IA4220 Transmitter Stage 2 – IA4420 Transceiver Stage 3 – IA4320 Receiver 5 This page is intentionally left blank 6 Radio Hardware IA4220/21 TRANSMITTER SECTION Contents - Schematic - 434 MHz Layouts - 915 MHz Layouts 7 SCHEMATIC: PUSH BUTTON DEMO TX BOARD 3 WP\ SO 2 GND 10u C1 VCC 8 B1 C3 GND R5 3k3 R4 SO 470 R1 R3 VCC GND 3k3 100p 100n - R2 10 k C2 6k8 + D1 HOLD\ SCK SI CS\ VCC 1 2 3 7 6 5 1 SCK SI CS SW1 EEPROM Array 4 VCC IC2 IC1 1 2 3 4 5 6 7 SCK VDD SEL IRQ WS1 RFP WS2 RFN WS3 MOD WS4 VSS CLK/SDO XTL 16 15 14 13 12 11 10 9 GND 1 2 FSK 3 4 SMDRET S4 1 2 3 4 SMDRET S3 1 2 3 4 SMDRET S2 1 2 3 4 SMDRET S1 8 SDI XTL 10 MHz LED 1 GND Fig 4.
