Scope
This document describes key hardware aspects of the Summit SDC-MSD40NBT radio module. This
document is intended to assist device manufacturers and related parties with the integration of this radio
into their host devices. Data in this document is drawn from a number of sources and includes information
found in the Broadcom BCM4329 data sheet issued in June of 2009.
The SDC-MSD40NBT is currently in pre-production and this document is preliminary. The information in
this document is subject to change. Please contact Summit or visit the Summit website at
www.summitdatacom.com to obtain the most recent version of this document.
Operational Description
This device is an SDC-MSD40NBT radio module which supports IEEE
802.11a/b/g/n standards via an SDIO (Secure Digital Input/Output) interface
and Bluetooth version 2.1 via a serial UART (Universal Asynchronous
Receiver/Transmitter) interface. The radio operates in unlicensed portions of
the 2.4 GHz and 5 GHz radio frequency spectrum. The device is compliant with
IEEE 802.11a, 802.11b, 802.11g, and 802.11n standards using Direct
Sequence Spread Spectrum (DSSS) and Orthogonal Frequency Division
Multiplexing (OFDM), and supports Bluetooth 2.1 using Frequency Hopping
Spread Spectrum (FHSS). The device supports all 802.11a, 802.11b, 802.11g,
802.11n, and Bluetooth data rates and automatically adjusts data rates and
operational modes based on various environmental factors.
When operating on channels in the UNII-2 and UNII-2 Extended bands that are
in the 5GHz portion of the frequency spectrum and are subject to Dynamic Frequency Selection
requirements, the SDC-MSD40NBT fully conforms to applicable regulatory requirements. In the event that
specified types of radar are detected by the network infrastructure, the SDC-MSD40NBT fully conforms to
commands from the infrastructure for radar avoidance.
The SDC-MSD40NBT interfaces to host devices via a 60-pin connector. The device is based on the
Broadcom BCM4329chip which is an integrated device providing a Media Access Controller (MAC), a
Physical Layer Controller (PHY or baseband processor), and fully integrated dual-band radio transceiver.
To maximize operational range, the SDC-MSD40NBT incorporates a 5 GHz power amplifier (PA) to
increase transmit power. The frequency stability for both 2.4 GHz (802.11b and 802.11g) and 5 GHz
(802.11a) operation is +/- 20 ppm.
The SDC-MSD40NBT has its own RF shielding and does not require shielding provided by the host
device into which it is installed in order to maintain compliance with applicable regulatory standards. As
such, the device may be tested in a standalone configuration via an extender card.
The device buffers all data inputs so that it will comply with all applicable regulations even in the presence
of over-modulated input from the host device. Similarly, the SDC-SSD40NBT incorporates power
regulation to comply with all applicable regulations even when receiving excess power from the host
device.
The SDC-MSD40NBTprovides two unique U.FL type antenna connectors tosupport dual band transmit
and receive diversity. Supported host device antenna types include dipole and monopole antennas.

Note Regarding SYS_RST_L and CHIP_PWD_L:
Simply releasing SYS_RST_L and CHIP_PWD_L does not guarantee that the BCM4329 chip in
the SSD40NBT module comes out of reset. Ensure that both VDD and VDDIO have been applied
to the SSD40NBT for at least 110 ms before attempting to initiate SDIO communications. A
slightly longer delay is better (safer).

Integration Considerations
The following Wi-Fi information should be taken into consideration when integrating the SSD40NBT.
Series resistors are recommended in all six SDIO lines (27-56 ohms typically):
SDIO_CLK
SDIO_CMD
SDIO_DATA_0
SDIO_DATA_1
SDIO_DATA_2
SDIO_DATA_3
Note: Although these values may vary with the properties of your host interface and the PCB, they are a
reasonable starting point.
Note: The series resistors in the SDIO bus provide several design benefits:
- If a host controller has too high of a drive strength, then bus ringing may result. Series resistors
can reduce this ringing on the I/O lines.
- Adding 27-56 ohms of series resistance on the SDIO bus will reduce sharp transitional edges,
which may reduce EMI.
- Having the series resistors in the PCB layout allows for design flexibility; If they are later found to
be unnecessary, zero (0) ohm jumpers may be used in their place
The following are also recommended:
47 K ohm pull-ups on the CMD line and four data lines: SDIO_CMD, SDIO_DATA_0, SDIO_DATA_1,
SDIO_DATA_2, SDIO_DATA_3
Note: No pull-up is required on the CLK line.
Note: Make sure to apply the proper voltage on the VDDIO input to the SiP to match the signaling
voltage of the SDIO host interface (1.8V or 3.3V typically, but it can be anything in between these
values).
Note: The SDIO host must wait a minimum of 110 ms before initiating access to the SDC-MSD40NBT
after VDD ramps up and settles.

Mounting
Three through-hole mounting with a 60-pin connector. Summit recommends a 1.5 mm bushing with a
conductive mounting screw to connect the exposed ground pads of the radio circuit board to the host
ground plane. A 1.5 mm conductive bushing with a maximum OD of 3.5 mm will maximize grounding of
the radio and help to reduce emissions from the radio circuit board.
Figure 11: Mounting Recommendations
RF Layout Design Guidelines
The following is a list of RF layout design guidelines and recommendation when installing a Summit radio
into your device.
Do not run antenna cables directly above or directly below the radio.
Do not place any parts or run any high speed digital lines below the radio.
If there are other radios or transmitters located on the device (such as a Bluetooth radio), place the
devices as far apart from each other as possible.
Ensure that there is the maximum allowable spacing separating the antenna connectors on the
Summit radio from the antenna. In addition, do not place antennas directly above or directly below the
radio.
Summit recommends the use of a double shielded cable for the connection between the radio and the
antenna elements.
Summit has provided three plated mounting holes that can be used for grounding. When additional
ground plane is required, you may use some or all of these grounded mounting holes.
Use proper electro-static-discharge (ESD) procedures when installing the Summit radio module.

Maximum 2.4 GHz Gain: 1.6 dBi (not used during testing)
Maximum 5 GHz Gain: 5 dBi
Tested and Certified 5 GHz Transmit Power: TBD
Note: If the formal test reports for the SDC-MSD40NBTshow that transmit power was decreased to less
than 100% on 2.4 GHz edge channels. Summit will make these transmit power reductions in
firmware for the edge channels. Integrators do not need to reduce transmit power on a channel-
by-channel basis to comply with band edge regulations.
Antennas of differing types and higher gains may be integrated as well. If necessary, with the Summit
Manufacturing Utility software utility, OEMs may reduce the transmit power of the SDC-MSD40NBT to
account for higher antenna gain. In some cases, OEMs may be able to reduce certification efforts by
using antennas that are of like type and equal or lesser gain to the above listed antennas.
