wi.dp1203-xxx-r datasheet 9 4. functional description the wi.dp1203-xxx-r tm 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 datasheet, available from the semtech website: http://www.semtech.com . the module incorporates an antenna switch and a saw filter placed on the rx path. figure 2: antenna switch chapter 4
wi.dp1203-xxx-r datasheet 10 5. operation modes when operating the xe1203f, it might by useful to qui ckly 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 regi ster are duplicated: the configuration set#1 and the configuration set #2. depending on the conf igswitch 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 t he 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. configswitch register switch pin rtparam_switch_ext configuration parameter swparam configuration set selected 0 switch is an output: ?1? in transmitter mode ?0? in the other mode 0 set #1 swparam_mode_1 swparam_power_1 swparam_rmode_1 swparam_t_delsig_in_1 swparam_freq_1 1 switch is an output: ?1? in transmitter mode ?0? in the other mode 0 set #2 swparam_mode_2 swparam_power_2 swparam_rmode_2 swparam_t_delsig_in_2 swparam_freq_2 x 0 0 set #1 swparam_mode_1 swparam_power_1 swparam_rmode_1 swparam_t_delsig_in_1 swparam_freq_1 x 1 0 set #2 swparam_mode_2 swparam_power_2 swparam_rmode_2 swparam_t_delsig_in_2 swparam_freq_2 table 4, configswitch, switch pin and swparam configuration register for more information about the data operation modes, please refer to the xe1205 datasheet chapter: description. you can find this at http://www.semtech.com . chapter 5
wi.dp1203-xxx-r datasheet 11 5.1. standard sequence for switching between receiver and transmitter the drop-in module wi.dp1203- xxx-r tm is able to switch between any configuration by using the 3-wire bus or by using the pin switch. this section descri bes the switching sequence from set #1 to set #2. figure 3: switching sequence
wi.dp1203-xxx-r datasheet 12 6. serial control interface a 3-wire bi-directional bus (sck, si, so ) is used to control the dp1203f. th e output signal, so, is provided by the wi.dp1203-xxx-r tm 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 definition and principles of operation . figure 4: serial control interface chapter 6
