2. Overall Description
2.1. Product Perspective
This Radio module version is constrained to 406.1125-419.9875MHz, 0dBm to 24dBm, GFSK modulation
and 30% maximum duty cycle.
The Radio modules is to achieve full interchangeability between product model lines, maintaining mechanical
and software interfaces as well as physical dimensions is a general objective.
2.1.1. User Interfaces
All interface between this module and the User will be software controlled by the product hosting this
module. Features such as Frequency, Power and Modulation are all controlled by the Host device.
2.1.2. Hardware Interfaces
This product will have two hardware interfaces, these are the RF Port and a 50 pin I/O connector
carrying the microcontroller interface and power lines.
The 50 pin interface will have a
4 wire serial interface, consisting of Clock in, Data out, Data in and Load.
Power: Vbat, 3V3 synth and E2Prom 3-5V
I2C interface to store personality.
Power control interface consisting of 2 wire power set and one wire PA amp on
Data I/O 1 wire out 1 wire in
Chip enable 1 wire.
2.1.3. Software Interfaces
This module will require the configuration of 15 Data Registers by the operating firmware that set the
operating parameters.
The AE system will provide the operational parameters to the operating firmware.
