DP1203
868 / 915MHz RF Modules
FUNCTIONAL DESCRIPTION
The DP1203 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 XE1203. For more information on the
XE1203, please refer to the Semtech web site.
All high frequency circuits and the 39MHz reference crystal are enclosed inside a shielding can. The module
incorporates an antenna switch driven by two external pins (RX and TX), and a SAW Filter placed between the
antenna port (RF IN/OUT). The switch provides a superior margin to satisfy the European or the North American
regulatory standards.

SERIAL CONTROL INTERFACE
A 3-wire bi-directional bus (SCK, SI, SO) is used to control the DP1203. The output signal, SO, is provided by
the DP1203 in opposition to the SCK and SI which need to be provided by the external application as an 8-bit
microcontroller. An access Read or Write with the XE1203 is possible only when the enable signal is active
(active LOW).
For more information about the 3-wire bus, please refer to the XE1203 datasheet chapter; Interface definition,
principles of operation.

OPERATING MODES
The DP1203 has 2 main operating modes (Mode 1, Mode 2); each mode is subdivided into 4 modes illustrated
in the table below. The switching between Mode1 and Mode 2 can be done either through the 3-wire bus
(Chip_config register) or by using the pin SWITCH. The selection depends on the Switch_ext which is a XE1203
register.

1.3 STANDARD SEQUENCE FOR SWITCHING BETWEEN RECEIVER AND TRANSMITTER
The drop-in module DP1203 is able to switch between any configuration by using the 3-wire bus or by using the
pin SWITCH. This section describes the switching sequence from Mode 1 to Mode 2.
Switching sequence by using the 3-wire bus
Switch_ext = 0 (Bit 3, Address 00010)
Switching sequence by pad SWITCH
Switch_ext = 1 (Bit 3, Address 00010)

TYPICAL APPLICATION
The schematic below shows the DP1203 interfaced with a Semetch's microcontroller XE8806A. In this typical
application, the pad SWITCH is used as an input and the two signals TX and RX are controlled directly by the
microcontroller.
