3 FUNCTIONAL DESCRI PTI O N

The True RF DP1203F is a cost effective high performance radio transceiver module designed for the wireless

transmission of digital information over distances of >500 meters in free space.

The module is based on the RF transceiver circuit from SEMTECH, the XE1203F. For more information on the

XE1203F, please refer to the XE1203F datasheet.

The module incorporates an antenna switch and a SAW Filter placed on the Rx path.

4 SERIAL CONTROL INTERFACE

A 3-wire bi-directional bus (SCK, SI, SO) is used to control the DP1203F. The output signal, SO, is provided by the

DP1203F in opposition to the SCK and SI which needs to be provided by the external application as an 8-bit

microcontroller. An access Read or Write with the XE1203F is possible only when the enable signal is active

(active LOW).

For more information about the 3-wire bus, please refer to the XE1203F datasheet chapter; Serial interface

definitio n a nd principles of operat io n.

5 OPERATION MODES

When operating the XE1203F, it might by useful to quickly switch between two pre-defined operating modes, to

save time and traffic on the 3-wire serial interface bus. This may occur when the XE1203F is required to switch

quickly between receive and transmit mode, when it has to operate on two different carrier frequencies, or when it

has to switch between the high linearity mode B and the high sensitivity mode A. For that purpose, the five

parameters stored in the SWParam Configuration Register are duplicated: the configuration set#1 and the

configuration set #2.

Depending on the ConfigSwitch 1-bit Register or the input level at the SWITCH pin, the XE1203F transceiver will

use either the SWParam configuration set#1 or the set #2. If the RTParam_Switch_ext configuration parameter is

low, then the SWParam configuration set is selected by the ConfigSwitch parameter – set#1 if ConfigSwitch is “0”,

set#2 if ConfigSwitch is “1”. If the RTParam_Switch_ext configuration parameter is high, then the SWParam

configuration set is selected by the SWITCH pin – set#1 if SWITCH is low, set#2 if SWITCH is high.
