Transmit and receive pins
The XDL Micro module uses pin 3 to receive data from an external device, such as
a computer, GPS receiver, or weather sensor, and uses pin 14 to transmit data to the
external device.
The external device transmits data to the XDL Micro transceiver on pin 3, so according to
the DTE naming convention, pin 3 is called the Tx Data pin. The external device receives
data from pin 14 on the XDL Micro transceiver, so this is called the Rx Data pin.
Antenna port
A coaxial antenna port is provided to connect the antenna system to the transceiver. The
antenna connector is a 50-Ohm MMCX type. Appendix B: Cables and Connectors, page
17 provides part numbers and manufacturer information for compatible interface and
RF connectors. Pacific Crest also provides custom manufactured cables designed to your
specific needs. For specific cabling requirements, please contact us for a quotation.
CAUTION – Do not transmit without first connecting an antenna as it may damage the
transceiver.
Compatibility
The transceiver is compatible with most modes of operation supported by the XDL,
ADL and PDL product families of radio modems. For an overview of the protocols and
modes that the transceiver supports, see Protocols and Operation Modes, page 10. The
compatibility also extends to the XDLCONF configuration software and the XDL Test
application that are supplied as part of the XDL Micro Developer’s Kit (P/N 70888-88).
10 XDL Micro Intergrator’s Guide
Protocols and Operation Modes
You can completely configure the transceiver using the XDLCONF software. Configuration
parameters define the DTE interface and the over-the-air protocol. Depending on your
application, you may need to change the factory default settings.
The following table shows the factory default settings of the transceiver.

11 XDL Micro Intergrator’s Guide
Electrical Considerations
Power supply
The transceiver has a power supply connection on pins 18, 23, 24, 25, 26, 27, and 28 of the
interface connector. If there is a potential for a ground path current loop due to incorrect
power application, Pacific Crest recommends that you insert a fusible link in the signal
ground to protect the transceiver.
The XDL Micro transceiver is designed to operate with an unregulated DC voltage level at
3.6 ±0.4V. The power supply must be capable of sourcing 2 A.
Data interface
The transceiver has one serial port. It is a data port that has a simple 3-wire CMOS
electrical interface with signals for transmitting data to, and receiving data from, the
transceiver, and for providing a reference ground for the Tx (pin 3) and Rx (pin 14) signals.
Note– Pacific Crest defines Tx and Rx as a DTE port. That is, an external device transmits
data to the radio modem’s Tx pin (pin 3) and receives data from the radio modem’s Rx pin
(pin 14).
CMOS input/output protection circuitry
The Tx signal terminates into a CMOS input port on the transceiver and should be driven
externally or pulled to ground through a 10 kΩ resistor. The absolute maximum voltage
applied to the Tx signal is -0.3 v to 3.3 V.
The Rx signal is CMOS outputs. Note that loading the RX signal increases the power
consumption of the transceiver and these should be limited to no more than 2.5 mA in
order to maintain performance across the temperature range.
CAUTION – Internal circuitry protects the inputs and outputs against damage caused by
high static voltages or electric fields. However, normal precautions are necessary to avoid
application of any voltage higher than the maximum-rated voltages.
NC pins
Pins 2, 4, 6, 8, 10, 12, 13, and 15 through 17 must be left with no connection.
12 XDL Micro Intergrator’s Guide
Power down pin
Pin 29 is the active low pin used to turn off power to the XDL Micro transceiver. The VIH
(Voltage Input High) minimum is 1.2 V and VIL (Voltage Input Low) maximum is 0.3 V. It
has a 10 K pull-up resistor to VCC. You can leave it unconnected (NC) if you do not want
to turn off the XDL Micro transceiver.
Error codes
The transceiver performs a variety of start-up and run-time tests to ensure optimal
operation. Tests include environmental as well as electrical measurements designed to
avoid damage to the unit while maintaining adequate operation.
A 50 Ω impedance coaxial MMCX style RF connector is provided to attach to an external
antenna system. The MMCX connector offers a positive friction locking mechanism that
is very reliable. In some circumstances it may be required to provide a physical stop to
prevent the MMCX plug from becoming disconnected due to extreme shock or vibration.
The transceiver requires an antenna and feed cable system that is impedance-matched
to 50 Ω. Pacific Crest recommends that you use a high-quality RG-178 or equivalent
coaxial cable for internal wiring of the RF signal from the MMCX connector to the panel
connector. Pacific Crest also recommends you select an antenna that has a low VSWR
(Voltage Standing Wave Ratio) (less than 1.5:1) and which is tuned for operation in the
band of the XDL Micro transceiver.
CAUTION – Incorrect impedance matching of the antenna, connectors, or cable degrades the
performance of the transceiver.
Shielding considerations
The transceiver is designed to operate in proximity to noise-generating circuitry.
However, certain radiated or conducted frequencies may degrade the performance of
the transceiver or make it inoperable. When possible, provide well-grounded shielding
between the transceiver and radiating circuits, such as power supplies, voltage-controlled
oscillators, and crystal oscillators.
13 XDL Micro Intergrator’s Guide
Frequency planning
The transceiver contains a very sensitive, dual-conversion, super-heterodyne receiver.
CAUTION – Radiated and conducted signals to and from the transceiver may cause problems
due to interference. Correct attention to frequency planning may reduce interference from
radiated or conducted frequencies that fall within the pass-bands of the filters at the IF
frequencies.
Pacific Crest recommends you first analyse the product frequency plan (including
harmonics) and then use a spectrum analyzer to determine the potential for interference
within the pass-bands of the various front-end and band pass filters.
The following table indicates the frequencies and pass-band filter characteristics that are
areas of potential interference.
Circuit Center frequency (MHz) Bandwidth (MHz)
RF front-end 438 70
First IF 54.45 0.015
Second IF 0.450 0.010
14 XDL Micro Intergrator’s Guide
Mechanical Considerations
EMI interferers
The transceiver is easily mounted in new and existing products. The transceiver is
specifically designed for operation in harsh environments. For best performance, mount
the radio away from potential EMI radiators and route RF signals apart from digital
signals.
CAUTION – To avoid interference between the signals, Pacific Crest recommends you do not
bundle the antenna interface cable with other signal cables internal to your product.
Shock and vibration
Sensitive receivers, such as that in the XDL Micro transceiver, are susceptible to
interference due to mechanical shock and vibration. To reduce the potential for
electromechanical interference, you must use a robust mounting scheme when you
integrate the transceiver into other systems. You may need to use a thin damping pad
between the mounting surface and the transceiver. Pacific Crest recommends that the
damping pads you use are made of PORON® or a similar material.
Thermal transfer
The transceiver requires additional thermal heat dissipation in order to supply maximum
output power at elevated ambient temperatures and high-duty cycles. The transceiver has
a thermal sensor and a firmware controlled limit switch. To prevent permanent damage
to the transmitter, the XDL Micro module shuts down when its internal temperature
reaches 85 °C (185 °F). The integrated heat sink is adequate for most bench top testing,
but when the transceiver is integrated into other systems you must consider additional
thermal heat sinking. The transceiver produces approximately 6 Watts of heat at full RF
power out.
For mounting diagrams and specification, see Appendix A: Mounting Guide, page 15.
Materials
The transceiver is housed in a metal shield that is a conductor and is electrically
connected to the ground and signal ground pins.

Standard enclosure
The following figure shows mounting holes locations and overall dimensions for the
transceiver.
CAUTION – Screws used to mount the transceiver to a mounting plate must not penetrate
the mounting surface of the transceiver by more than 0.20 inches. Screws that penetrate
beyond this distance may cause damage.
