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.
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.
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.
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 .
