　　描述

　　Dolphin is a Frequency Hopping Spread Spectrum (FHSS) Wireless UART chipset for the 902-928 MHz US ISM Band. The Dolphin chipset consists of the TRF6903 RF transciever and the digital baseband ASIC DBB03A and comes FCC pre-certified.

　　DOLPHIN-HP-EVM is the evaluation kit for the High Power Dolphin chipset. With this hardware the user is able to demonstrate, test, and evaluate two way point-to-point communication. The evaluation kit contains:

　　Two High Power daughter cards

　　Two Interface cards

　　Two RS-232 Serial Cables to connect to a computer

　　Graphical evaluation software

　　All applicable literature and data sheet

　　To demonstrate the broADCast capability of the Dolphin chipset, an additional adder kit is available. Please see DOLPHIN-LP-ADDER for a low power adder kit, or DOLPHIN-HP-ADDER for a high power adder kit.

　　特性

　　Hardware Features:

　　Chipset Solution - TRF6903 RF Transceiver and DBB03 Digital Baseband ASIC (firmware in ROM-based program memory)

　　FHSS FSK operation in the 902-928 MHz US ISM band

　　Fastest frequency hopping solution available resulting in fast acquisition and less power consumption. (Channel lock time of 200μs; No calibration needed when frequency hopping)

　　Evaluation software or system micro can be used to evaluate/program the Dolphin chipset using a defined host-interface protocol

　　+23 dBm output Power

　　2.7-3.6 V operation

　　RF bit rate of 38.4 kbps

　　50 hopping channels and multiple hop tables

　　FCC pre-certified per testing at LS Compliance

　　Transmisson Range of 1 mile

　　-101 dBm sensitivity at 38.4 kbps bit rate

　　Software Features:

　　Simple, hardware UART interface for an external system microcontroller

　　AcknowLEDgement/Retry for reliable data transfer

　　Packet routing to increase communication range

　　Supports Point-to-Point and Broadcast Networks

　　Hierarchical Network definition: Each Transceiver has a Transceiver ID(unique), Network ID and System ID

　　U

　　p to 65536 Transceivers can be configured within a single System

　　Network Partitioning: Only Transceivers with same System ID, Network ID and same hopset communicate

　　Up to 16 distinct hopsets. Each hopset contains 50 frequencies. Transceivers with different hopsets will not communicate

　　Modular Firmware Facilitates Easy Customization
