1 List of applicable FCC rules

The following FCC rules are applicable to the equipment:

•CFR 47, Part 15, Subpart C

•CFR 47, Part 2, Subpart J –Radiofrequency radiation exposure: portable devices

2 Summary of operational use conditions

2.1 Antenna configuration

In addition to the general requirement to use only authorized antennas, the grant also requires a

separation distance of at least 20 cm from the antenna(s) to all persons. The antenna(s) must not

be co-located with any other antenna or transmitter (simultaneous transmission) as well. If this

cannot be met, a Permissive Change as described below must be made to the grant.

☞In order to support verification activities that may be required by certification laboratories,

customers applying for Class-II Permissive changes must implement the setup described in

Radio Test Guide for NXP based modules.

If the module is to be co-located with another transmitter, additional measurements for

simultaneous transmission are required. The results must be added to the grant file as a Class II

Permissive Change.

If the authorized antennas and/or antenna trace design cannot be used, the new antenna and/or

antenna trace designs must be added to the grant file. This is done by a Class I Permissive

Change or a Class II Permissive Change, depending on the specific antenna and antenna trace

design.

•Antennas of the same type and with less or same gain as an already approved antenna

can be added under a Class I Permissive Change.

•Antenna trace designs deviating from the reference design and new antenna types are

added under a Class II Permissive Change.

•For 5 GHz modules, the combined minimum gain of antenna trace and antenna must be

greater than 0 dBi to comply with DFS testing requirements.

2.2 Antenna gain

The antenna gain in each band must not exceed the following:

4 Antenna interfaces:

4.1 Wi-Fi and Bluetooth antennas

JODY-W2 provides two antenna pins, one for dual-band Wi-Fi connectivity (ANT1) and another

for Bluetooth (ANT0). The following recommendations apply to developing an antenna interface

for the JODY-W2 module:

•Where possible, consider integrating in the end product the u-blox Antenna Reference

Design to minimize the effort on the certification process.

•The ANT0 and ANT1 pins of JODY-W2 have a nominal characteristic impedance of 50 Ω

and must be connected to the external antennas through a 50 Ωtransmission line to

allow proper RF transmission and reception.

•Good isolation must be provided between the various antennas in the system. Special

care shall be taken to maximize isolation between the antennas operating in the same or

nearby bands.

For information describing how to properly design circuits compliant with these requirements,

see Antenna interfaces.

4.2 Approved antenna designs

JODY-W2 modules come with a pre-certified design that can be used to save costs and time

during the certification process. To minimize this effort, the customer is required to implement

antenna layout according to u-blox antenna reference designs. Reference design source files can

be provided on request by u-blox.3

For Bluetooth and Wi-Fi operation, the module has been tested and approved for use with the

antennas listed in the JODY-W2 approved antennas. The module may be integrated with other

antennas. In this case, the OEM installer must certify his design with respective regulatory

agencies.

4.3 Approved antennas

The antenna should be installed and operated with minimum distance of 20 cm between the

radiator and nearby persons.

4.3 Other remarks

4.3.1 Unused pins

☞JODY-W2 modules have pins that are reserved for future use (NC). These pins must be left

unconnected on the application board.

4.3.2 GPIO usage

☞The reconfiguration of signals marked as GPIOs on the JODY-W2 module for applications not

listed in this document depends on the respective firmware release.

5 Design-in

5.1 Overview

For an optimal integration of JODY-W2 series modules in the final application board, it is

advisable to follow the design guidelines described in this chapter. Every application circuit must

be properly designed to ensure that the related interface functions correctly, but several specific

points require special attention during the design of the application device.

The following list provides a rank of importance in the application design, starting from the

highest relevance:

•Module antenna connection: ANT0 and ANT1 pins.

Antenna circuit affects the RF compliance of the device integrating JODY-W2

modules with applicable certification schemes. For schematic and layout design

recommendations, see also Antenna interfaces.

•Module supply: VBAT, VIO/1V8, and GND pins.

The supply circuit affects the RF compliance of the device integrating JODY-W2 modules

with applicable certification schemes. Follow the General high-speed layout guidelines.

•High speed interfaces: SDIO pins.

High speed interfaces can be a source of radiated noise and can affect the compliance

with regulatory standards for radiated emissions. Follow the General high-speed layout

guidelines and recommendations for the SDIO 3.0 interface.

•System functions: PDn and pins described as Configuration pins.

Accurate design is required to ensure that the voltage level is well defined during

module boot. Follow the General high-speed layout guidelines.

•Other pins: High speed UART, PCM, specific signals and NC pins.

Document Information Page 10 of 31

FSS JODY-W263 Integration Instructions Rev 02.docx

www.foresightsports.com

Accurate design is required to ensure proper functionality. Follow the General high-

speed layout guidelines and recommendations for the High-speed UART interface.

5.2 Antenna Interfaces

JODY-W2 modules provide the following two RF interfaces for connecting the external antennas:

•The ANT0 port for Bluetooth connectivity.

•The ANT1 port for Wi-Fi connectivity.

Both the ANT0 and the ANT1 ports have a nominal characteristic impedance of 50 Ω and must

be connected to the related antenna through a 50 Ω transmission line to allow proper

impedance matching along the RF path. A bad termination of the ANT0 pin (Bluetooth) or the

ANT1 pin (Wi-Fi) may result in poor performance of the module.

For the dual antenna modules, the isolation between the two antennas should be maximized,

the requirements specified in Table 7 and Table 8 should be followed to ensure good

performance.

⚠According to FCC regulations, the transmission line from the antenna pin in the module to the

antenna or antenna connector on the host PCB is considered part of the approved antenna

design. Consequently, module integrators must either follow exactly one of the antenna

reference designs used in the module’s FCC type approval or certify their own designs. See also

the antenna reference design.

5.2.1 RF Transmission Line Design

RF transmission lines such as the ones from the ANT0 and ANT1 pins up to the related antenna

connectors must be designed so that the characteristic impedance is as close as possible to 50

Ωillustrates the design options and the main parameters to be considered when

implementing a transmission line on a PCB:

•Microstrip: track coupled to a single ground plane, separated by dielectric

material),

•Coplanar microstrip: track coupled to ground plane and side conductors,

separated by dielectric material).

•Stripline: track sandwiched between two parallel ground planes, separated by

dielectric material).

The coplanar microstrip is the most common configuration for a printed circuit board

(PCB).
