CohdaMobility MK5 Module – Datasheet Page 6/27 Cohda Wireless Pty Ltd Confidential Information 1 Functional Description 1.1 Overview The MK5 Module is designed to provide a compact platform for the deployment of advanced connected vehicle applications which can exploit the significant performance of the CohdaMobility Radio in mobile environments. The MK5 Module is an automotive qualified single or dual channel CohdaMobility IEEE 802.11p radio, operating from -40C to +85C PCB ambient temperature. The MK5 module is a complete IEEE 802.11p dual-antenna radio, incorporating Link-, MAC- and PHY Layers and 5.9GHz RF Front-End. It is a surface mount module that only requires connections to 5.9GHz antennas, USB connection to a host processor, and power supply. The key features of the MK5 Module are summarised in Table 1below. Table 1 - Key Features of the MK5 Module Parameter Specification Frequency Bands 5.9 GHz 760 MHz (Future) 2.4 GHz (Future) Transmit Power 5.9 GHz: -10 to +23 dBm 5.9 GHz: Class C Receive Sensitivity 5.9 GHz: -97 dBm @ 3Mbps Antenna Diversity 5.9 GHz only: CDD Transmit Diversity MRC Receive Diversity Bandwidth 10 MHz 20 MHz (Future) Data Rates 3 to 54 Mbps Power Supply 3.3V 5.0V Power Consumption 4W (Max) Temperature Range -40ºC to +85ºC Dimensions 40 (L) x 30 (W) x 4 (H) mm Standards Conformance IEEE 802.11p – 2010 ETSI ES 202 663 IEEE 1609.4 – 2010
CohdaMobility MK5 Module – Datasheet Page 7/27 Cohda Wireless Pty Ltd Confidential Information 1.2 CohdaMobility MAC The CohdaMobility MAC implements a full IEEE 802.11p compliant MAC layer, for one or two independent radio channels. The MAC runs on the ARM processor of the SAF5100. The CohdaMobility MAC provides fast, time-synchronised channel switching functionality. It also provides support for multiple queue sets, allowing packets to be queued while the PHY/MAC is operating on another channel. The MAC provides the following operating modes: - Single radio, single channel operation. o Only one of the radios are used - Single radio, time-synchronised multi-channel operation o Channel switching between two channels with independent sets of transmit queues. - Dual radio, multi-channel operation o Independent MAC/PHY entities operating concurrently on different radio channels. o Optional coordination between channels to avoid self-interference when operating on close radio channels. - Dual radio time synchronised multichannel operation. o As above, plus one of the radios optionally performs channel switching between two channels with independent sets of transmit queues The CohdaMobility MAC provides full IEEE 802.11p support. Full support for MAC time-synchronisation is provided via an external GNSS receiver under software control or using an external 1PPS signal. Other features of the MAC include: - Radio channel measurements o Channel utilisation (ratio of channel busy time to measurement duration) o Channel active ratio (proportion of time that the radio is tuned to the SCH or CCH, respectively) o Per-channel statistics (number of packets successfully transmitted, number of packets that failed to transmit, number of packets successfully received, and number of packets received in error. Broken down according to broadcast, multicast, and unicast packets) o Received signal and noise power levels.
CohdaMobility MK5 Module – Datasheet Page 8/27 Cohda Wireless Pty Ltd Confidential Information 1.3 Performance 1.3.1 Receiver Sensitivity The receive sensitivity of the MK5 Radio is presented in Table 2 for single and dual receive antennas, operating at 5.9GHz in DSRC 10MHz bandwidth mode. The packet error rate (PER) is less than 10% at a PSDU length of 1,000 octets for these input levels. The receive sensitivity is measured with a signal input directly to the antenna ports. Example plots are presented in Figure 1 and Figure 2 overleaf.

CohdaMobility MK5 Module – Datasheet Page 13/27 Cohda Wireless Pty Ltd Confidential Information 1.3.5 Adjacent Channel Rejection The adjacent channel rejection of a MK5 Module is measured by setting the desired signal strength 3 dB above the receive sensitivity specified in Table 18-14 of the IEEE802.11-2012 standardTable 2 and raising the power of the interfering signal until 10% PER is caused for a PSDU length of 1000 octets. The power difference between the interfering and the desired channel is the corresponding adjacent channel rejection. The interfering signal in the adjacent channel is a conformant OFDM signal, meeting the DSRC Class C mask, unsynchronized with the signal in the channel under test. The receive sensitivity values are measured with a signal input directly to the Antenna Ports. Measured results for the MK5 Module adjacent channel rejection, together with the target nACR values obtained from the IEEE802.11-2012 standard, are provided in Table 7 Table 7 - Adjacent Channel Rejection (ACR) Modulation Target ACR [dB] Target opt. enh.

CohdaMobility MK5 Module – Datasheet Page 14/27 Cohda Wireless Pty Ltd Confidential Information 1.3.6 Non-Adjacent Channel Rejection The non-adjacent channel rejection of a MK5 Module Radio is measured by setting the desired signal’s strength 3 dB above the rate-dependent sensitivity specified in Table 18-14 of the IEEE802.11-2012, and raising the power of the interfering signal until a 10% PER occurs for a PSDU length of 1000 octets. The power difference between the interfering and the desired channel is the corresponding nonadjacent channel rejection. The interfering signal in the non-adjacent channel is a conformant OFDM signal, targeting the DSRC Class C mask, unsynchronized with the signal in the channel under test.

The PHY RF front-end can provide multiple radio configurations, allowing the MK5 Module to implement single or dual radio DSRC systems. The RF sub-system provides separate antenna ports for 5GHz bands via castellated edges of the module. RF output pin sets (separate Rx and Tx pins) are available for 760MHz and 2.4GHz. These two frequency bands will require off-board RF Front-End circuits for complete integration into a radio system. In the dual-radio configuration, the CohdaMobility PHY effectively operates as two independent PHY modules, each operating on a different radio channel. The module can support the dual-radio configurations shown in Figure 8.

The CohdaMobility PHY provides 2-antenna diversity transmission and reception at 5.9GHz for optimum radio performance. A summary of the operating modes and functionality of the CohdaMobility PHY are as follows: - Single-channel mode (1 or 2 antenna diversity operation). - Dual-channel mode (1 antenna per channel), 2 independent IEEE 802.11p radios operating on different radio channels. - 10MHz (DSRC) channel bandwidth modes. - Supported frequency bands: o As per Table 1 - Transmit mask meeting IEEE 802.11p Class C (5GHz band). - IEEE 802.11p enhanced adjacent channel receiver performance. - Transmit antenna cyclic delay diversity (2 antenna operation in 5.9 GHz band only). - Transmit power control (0.5dB steps). - Fast mode changes for synchronised channel switching systems.
CohdaMobility MK5 Module – Datasheet Page 17/27 Cohda Wireless Pty Ltd Confidential Information 1.5.2 Reset The reset line will keep the SAF5100 and TEF5100 IC’s on the MK5 module in reset. Contact Cohda Wireless for specific information on the implementation of this pin. 1.5.3 GPIO Refer Table 10. 1.5.4 1PPS The 1PPS input is required by the radio to align transmissions when channel switching and for timekeeping. The MK5 accepts pulses with standard CMOS 1V8 levels. The signal should have the rising edge on the UTC second. Pulse width should be 1ms nominally. Pulse widths up to 250ms should be tolerable. As with all MK5 input this signal must NEVER be driven into the MK5 when the internal MK5 supplies are off. Contact Cohda Wireless for specific information on the implementation of this pin. 1.5.5 USB Refer Table 10. 1.5.6 Power Supplies The MK5 module 5.0v supplies are designed to support up to 400mA current draw for each radio (producing a continuous sinus wave at maximum transmit power). The 3.3v power supply is designed to support up to 1A, assuming maximum load on all the DSP and RF transceiver functions. The total power consumption of the MK5 module will not exceed 4W in normal operation, and typically consumes only 2.1W.

CohdaMobility MK5 Module – Datasheet Page 20/27 Cohda Wireless Pty Ltd Confidential Information P=Power I=Input O=Output BI=Bidirectional RF=Radio Frequency NOTES 1. This pin should be driven by an open drain/collector device. It is internally pulled high to 1V8 by 10k. When reset it should be below 0.2V. 2. This pin is internally pulled to pin 3 and 4, the 3V3 supply lines. This should not be shorted or pulled to ground. See HW manual. 3. These 3 pins should never be loaded by more than 500 kΩ to ground or 1V8 as this would interfere with correct internal operation at boot. 4. The 5V0_PAn pins should have bypass caps located at the pin. These are NOT connected internally and each supply is isolated to its own PA. Supply must be provided whenever the module main supply is powered. 5. The SPI bus is nominally an output on all modules. Internally, depending upon version of module, there may be a flash memory on this bus. Direction of these lines may be swapped on some versions of the module depending upon customer requirements. Always check your modules model and version against the HW documentation. 6. This line is optionally a SPI CS line. In other cases it may be used as a GPIO. Please check model number against HW documentation for how to use this pin in your application. 7. The USB interface is only between the module and host processor for short impedance controlled traces. The data and VBUS signals should only be applied to these pins when the module has power applied otherwise damage may occur. 8. This UART is not yet implemented but may be used in the future for customer specific or Cohda Wireless use. 9. This input, as with all inputs, should not be driven in to the device when the power is not supplied to the module otherwise damage will occur.

The MK5 module is an Electrostatic Sensitive Device (ESD) and require special precautions when handling. In addition to standard ESD safety practices, the following measures should be taken into account whenever handling the receiver: - Unless there is a galvanic coupling between the local GND (i.e. the work table) and the PCB GND, then the first point of contact when handling the PCB must always be between the local GND and PCB GND. - When handling the RF pin, do not come into contact with any charged capacitors and be careful when contacting materials that can develop charges (e.g. antenna, coax cable ~50-80 pF/m, soldering iron, …) - To prevent electrostatic discharge through the RF input, do not touch any exposed antenna area. If there is any risk that such exposed antenna area is touched in non ESD protected work area, implement proper ESD protection measures in the design. - When soldering RF connectors and patch antennas to the receiver’s RF pin, make sure to use an ESD safe soldering iron (tip).
