Summit User’s Guide – SDC-SSD40L 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.

Summit User’s Guide – SDC-SSD40L Mounting Summit specializes in the design and manufacturing of Wi-Fi radio modules and cards. Although we understand that every system is different, our expertise does not extend to the system level. Because of this, we can provide only integration guidelines and not individual design reviews and approvals. The SDC-SSD40L is a Quad Flat pack with No Leads (QFN) System in Package (SiP).
Summit User’s Guide – SDC-SSD40L Solder Stencil Opening for Pads: 1:1 to 1:0.9 (dependent on solder type) Solder Paste Type: No-Clean as the soldered part to board clearance will not allow for adequate post solder cleaning. Rework is technically challenging due to parts on the SIP reflowing at the same temperature needed for rework. The SDC-SSD40L cannot be lifted by the shield during rework. As such, removal of part for rework is not recommended.
Summit User’s Guide – SDC-SSD40L Regulatory Summit has received a Limited Modular Approval for this radio with the limitation that it must essentially be mounted on an MSD40L layout in order to have the Summit FCC ID attached to the device.
Summit User’s Guide – SDC-SSD40L B. PCB layout considerations The PCB board stack is shown below using 2-Layer FR4, lead-free solder finish plating, green solder mask on both sides and white silkscreen on both sides. Gerber files are shown below in detail. Figure 2: Components placement and trace route on the top layer. Via hole is of 10 mils size Figure 3: Components location of the top layer 17 © 2011 – 2012 Summit Data Communications, Inc. All rights reserved.
Summit User’s Guide – SDC-SSD40L Figure 4: Bottom layer On the bottom layer, a complete ground plane under the SSD40L is must to ensure the rf signal is well referenced. Also, the RF trace impedance between the SDC-SSD40L (Pin 56) and the antenna connector (J1) should be controlled within 50 ohm +/-10% and keep the trace as short as possible (recommend less than 100 mils) to reduce the trace lose.
Summit User’s Guide – SDC-SSD40L D. Design and testing verification for ensuring compliance Follow the reference design using the same components as when integrating the SDC-SSD40L. Use the same PCB material (FR4) with the same board stake thickness (0.062”). The RF trace between the SDC-SSD40L (Pin 56) and the antenna connector (J1) should be controlled within 50 ohm +/-10%; keep the trace as short as possible (less than 100 mils is recommended) to reduce the trace loss.
Summit User’s Guide – SDC-SSD40L User’s Guide Requirements As outlined in the Operational Description, the SDC-SSD40L complies with FCC Part 15 Rules for a Modular Approval. To leverage Summit’s grant, the conditions below must be met for the host device into which the SDC-SSD40L is integrated: 1. The antenna is installed with 20 cm maintained between the antenna and users. 2. The transmitter module is not co-located with any other transmitter or antenna that is capable of simultaneous operation. 3.
Summit User’s Guide – SDC-SSD40L 2. Increase the separation between the equipment and receiver. 3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. 4. Consult the dealer or an experienced radio/TV technician for help. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This device complies with Part 15 of the FCC Rules.
