DESCRIPTION

The DBB03A is a baseband ASIC for the "Dolphin" reference design. The firmware for the Dolphin reference

design resides in the ROM-based program memory of the DBB03A, and thus can be readily interfaced with a

TRF6903 single-chip RF Transceiver to generate a frequency hopping wireless UART "Dolphin" reference design

chipset. This is illustrated in Figure 1.

The DBB03A baseband ASIC in addition to being a RF baseband processor is also responsible for

communications with an external host/system micrcontroller. In a typical end user application, the Dolphin chipset

will be connected up to an external host/system microcontroller that will send configuration messages, RF

transmission messages into the Dolphin chipset, or receive status, RF messages received from the Dolphin

chipset.

Any catalog low-cost host/system microcontroller can be interfaced to the Dolphin chipset as long as the Dolphin

host interface protocol for communication is adhered to. (See Application Note Dolphin - Frequency Hopping

Spread Spectrum Chipset Host Interface Protocol TI Literature SWRA043) Texas Instruments recommends its

ultra-low power MSP430 series of microcontrollers to interface with Dolphin.

The interface between the DBB03A baseband ASIC and an external host/system microcontroller is a simple

UART consisting of RX and TX data lines. (See Application Note Interfacing Dolphin to an External System

Microcontroller, TI Literature SWRA045).

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
