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
