It supports the IEC-60958 stereo digital audio bus standards, e.g., S/PDIF and AES3/EBU. The RN52 audio interface circuit consists of: • Stereo audio CODEC • Dual audio inputs and dual outputs • Configurable S/PDIF and I2S interface The audio input circuitry has a dual audio input that can be configured as single-ended or fully differential and programmed for microphone or line input. It has an analog and digital programmable gain stage so that it can be optimized for different microphones. See Figure 1-4. www.rovingnetworks.com STEREO AUDIO CODEC INTERFACE The built-in CODEC uses a fully differential architecture in the analog signal path, which results in low noise sensitivity and good power supply rejection while effectively doubling the signal amplitude. It operates from a 1.5 V single power supply and uses a minimum of external components. See Figure 1-5.

MIC_BIAS requires a minimum load to maintain regulation. MIC_BIAS maintains regulation within 0.199 and 1.229 mA. Therefore, if you use a microphone with specifications below these limits, the microphone output must be pre-loaded with a large value resistor to ground. Version 1.1 3/19/13 Advanced Information page 8 RN52-DS 2.0 APPLICATIONS 2.1 The following sections provide information on designing with the RN52 module, including restoring factory defaults, using the LED interface, minimizing radio interference, solder reflow profile, typical application, etc. FIGURE 2-1: Minimizing Radio Interference When laying out the host PCB for the RN52 module, the areas under the antenna and shielding connections should not have surface traces, ground planes, or exposed via (see Figure 2-1). For optimal radio performance, the RN52 module’s antenna end should protrude at least 31 mm beyond any metal enclosure. Figure 2-2 shows examples of good, bad, and acceptable positioning of the RN52 on the host PCB. MINIMIZING RADIO INTERFERENCE (Top View) 31 mm Keep area around antenna (approximately 31 mm) clear of metallic structures for best performance 31 mm Edge of Ground Plain 4.6 mm 21.4 mm Dimensions are in millimeters FIGURE 2-2: PCB EXAMPLE LAYOUT RN52 Good RN52 Bad www.rovingnetworks.com RN52 RN52 Acceptable Acceptable Version 1.1 3/19/13 Advanced Information page 9 RN52-DS 2.2 LED Interface 2.3 The RN52 includes two pads dedicated to driving the LED indicators. The firmware can control both terminals, and the battery charger can set LED0. The terminals are open-drain outputs; therefore, the LED must be connected from a positive supply rail to the pad in series with a current limiting resistor. You should operate the LED pad (LED0 or LED1 pins) with a pad voltage below 0.5 V. In this case, the pad can be thought of as a resistor, RON. The resistance—together with the external series resistor—sets the current, ILED, in the LED. The current is also dependent on the external voltage, VDD, as shown in Figure 2-3. Device Firmware Updates The module has a device firmware update (DFU) mode in which you use the USB interface to update the firmware. ImplementingImplementing the DFU feature is recommended highly because firmware updates offer new features and enhance the module’s functionality. Follow the reference design shown in Figure 2-7 to support this mode. Note: A 47 KΩ pull-down resistor (R2 in Figure 2-4) is required on GPIO3 even if you do not use the USB for DFU. FIGURE 2-4: FIGURE 2-3: VDD C4 LED Forward Voltage, VF GPIO3 RLED LED0 or LED1 Resistor Voltage Drop, VR 2.4 The LEDs can be used to indicate the module’s connection status.

You can use this pin to reset the module to its factory default settings, which is critical in situations where the module has been misconfigured. To reset the module to the factory defaults, GPIO4 should be high on power-up and then toggle low, high, low, high with a 1 second wait between the transitions. The module is connectable.

TYPICAL APPLICATION CIRCUIT FOR A2DP AUDIO STREAMING & AVRCP REMOTE CONTROL page 13 RN52-DS 3.0 REGULATORY APPROVAL This section outlines the regulatory information for the RN52 module for the following countries: • • • • • United States Canada Europe Australia New Zealand 3.1 Contains Transmitter Module FCC ID: T9J-RN52 or Contains FCC ID: T9J-RN52 United States The RN52 module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C “Intentional Radiators” modular approval in accordance with Part 15.212 Modular Transmitter approval. Modular approval allows the end user to integrate the RN52 module into a finished product without obtaining subsequent and separate FCC approvals for intentional radiation, provided no changes or modifications are made to the module circuitry. Changes or modifications could void the user’s authority to operate the equipment. The end user must comply with all of the instructions provided by the Grantee, which indicate installation and/or operating conditions necessary for compliance. The finished product is required to comply with all applicable FCC equipment authorizations regulations, requirements and equipment functions not associated with the transmitter module portion. For example, compliance must be demonstrated to regulations for other transmitter components within the host product; to requirements for unintentional radiators (Part 15 Subpart B “Unintentional Radiators”), such as digital devices, computer peripherals, radio receivers, etc.; and to additional authorization requirements for the non-transmitter functions on the transmitter module (i.e., Verification, or Declaration of Conformity) (e.g., transmitter modules may also contain digital logic functions) as appropriate. 3.1.1 installed must also display a label referring to the enclosed module. This exterior label can use wording as follows: LABELING AND USER INFORMATION REQUIREMENTS The RN52 module has been labeled with its own FCC ID number, and if the FCC ID is not visible when the module is installed inside another device, then the outside of the finished product into which the module is This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation A user’s manual for the product should include the following statement: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. Additional information on labeling and user information requirements for Part 15 devices can be found in KDB Publication 784748 available at the FCC Office of Engineering and Technology (OET) Laboratory Division Knowledge Database (KDB) http://apps.fcc.gov/oetcf/ kdb/index.cfm. 3.1.2 RF EXPOSURE All transmitters regulated by FCC must comply with RF exposure requirements. OET Bulletin 65, Evaluating Compliance with FCC Guidelines for Human Exposure www.rovingnetworks.com Version 1.1 3/19/13 Advanced Information page 14 RN52-DS to Radio Frequency Electromagnetic Fields, provides assistance in determining whether proposed or existing transmitting facilities, operations or devices comply with limits for human exposure to Radio Frequency (RF) fields adopted by the Federal Communications Commission (FCC). The bulletin offers guidelines and suggestions for evaluating compliance. If appropriate, compliance with exposure guidelines for mobile and unlicensed devices can be accomplished by the use of warning labels and by providing users with information concerning minimum separation distances from transmitting structures and proper installation of antennas. The following statement must be included as a CAUTION statement in manuals and OEM products to alert users of FCC RF exposure compliance: To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended.

Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Transmitter Antenna (from Section 7.1.2 RSS-Gen, Issue 3, December 2010): User manuals for transmitters shall display the following notice in a conspicuous location: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.
