33-1253 Technical description: Introduction: The 33-1253 consists of a 2.4GHz dongle and a 2.4GHz headphone. Any analog music source that is applied to the dongle will be sent to the headphone via 2.4GHz RF link without any compression. The audio being sent by the dongle will be reproduced at the headphone side. Dongle operation: The role of the dongle is to accept any analog audio input and transmit the audio data to the corresponding headphone. ADC: The audio encoding is done by the ADC chip uDA1361TS (U4). The uDA1361TS is a single chip stereo analog-to-digital converter employing bit-stream conversion techniques. The ADC chip is set to master mode and system clock apply to the chip is about 11.29MHz (fsys). Therefore the sampling frequency is 44.1KHz (fsys/256) and with a resolution of 16 bit digital data. 2.4GHz wireless audio streamer: The digital data will then be sent to the 2.4GHz wireless audio streamer chip nRF24Z1 (U1). U1 works as an 2.4GHz RF transceiver with 4MBit/S data rate. It handles audio I/O, RF protocol and RF link management. The EEPROM chip (U2) stores the initial configuration of the U1. Once the unit is powered on, U1 goes into a power on reset, and the reset is held until the supply voltage is kept higher than the minimum operation voltage (2V) for a few millisecond. When the reset is released, the chip needs to be configured. It will look for the external EEPROM (U2) memory on the SPI master interface. Then configuration data is load from U2. Once U1 is configured, it starts the link-locate state that the dongle will try to establish link with the corresponding headphone by iteratively sending short search packages on all available channels until acknowledge is received from the corresponding headphone. Once the acknowledge is received, the dongle will enter the synchronization state. This synchronization state takes care of synchronizing the channel hopping engine on dongle and headphone, to secure that both parts follows the same hopping sequence. Which channel to start from is implicitly found during the link-locate state. When the dongle and headphone are in synchronization mode, the audio stream formats are converted to the nRF24Z1 RF protocol and transferred over the air. Power step up: The operation voltage is kept at 2.5V by a step up chip XC6371C251PR (U6) that is supplied by battery voltage. FCC ID: AAO3301253T Low battery: The battery monitor chip XC61CN2002MR/BU4820 (U9) that connects its input to the battery, works as a 2V battery monitor chip. When the battery voltage drops below 2V, it’s output will be dropped from Vdd (2.5V) to zero volt. Then the ADC chip (U4) is powered down and the LED (D3) will also be turned off. Battery charging for both dongle and headphone: Once the charging hub (provided) is connected to the power jack of either the dongle or the headphone. The battery voltage is disconnected from the main circuit and therefore the unit can not be operated when it is charging. FCC ID: AAO3301253T 32-1253 uses a single chip transceiver IC from Nordic nRF24Z1. RF PART The single chip transceiver IC contains all necessary RF circuit. It converts the RF FSK signal picked up by the antenna for further processing. Besides, the base band digital signal, including voice and commands, will be modulated to FSK format on the RF carrier during transmission. The main building blocks of the RF parts includes a LNA, Mixer, IF Band pass filter, VCO with frequency synthesiser, RF power amplifier for transmission. Among those building blocks, the RF circuit can be divided into two sections. A: RX section This product employs traditional single conversion architecture with the following functional blocks: 1. The LNA has low noise figure and high insertion gain. 2. The LO signal is generated VCO and the LO frequency is controlled by the frequency synthesizer after received command from external MCU. 3. The mixer is to convert RF signal to an IF signal. This IF signal will further filter by the IF band pass filter. 4. The IF signal is then down converted to digital signals, i.e. CLK and DATA. 5. The digital DATA is further convert to analogue voice signal through the external DAC IC. B: TX section 1. The digital DATA is from the external ADC and it is applied to the transceiver IC. 2. It is further filtered by the GFSK filter before going to the VCO and the frequency of transmission is controlled by the frequency synthesizer. 3. The FSK modulated signal is amplified by the internal PA. 4. The amplified RF signal is applied to the antenna with the external matching circuit. FCC ID: AAO3301253T

33-1253 Designated frequency hopping algorithm: Pseudorandom Frequency Hopping Sequence Describe how the hopping sequence is generated. Provide an example of the hopping sequence channels, in order to demonstrate that the sequence meets the requirement specified in the definition of a frequency hopping spread spectrum system. The frequency hopping is implemented in 18 non-overlap channels. The hopping is sequentially after the contents of the frequency hopping table CH01, CH08, CH14.... CH11, CH17, CH06 and so on. The example of the hopping sequence channels table shown below. Hopping table. (Total 18 channel frequencies in each sequences) Channel Table Sequence 1 Sequence 2 Channel 01 2404.320 MHz Channel 01 2404.320MHz Channel 07 2428.310 MHz Channel 02 2408.300 MHz Channel 08 2432.310MHz Channel 16 2468.320 MHz Channel 03 2412.310 MHz Channel 14 2460.330MHz Channel 08 2432.310 MHz Channel 04 2416.290 MHz Channel 03 2412.310MHz Channel 17 2472.350 MHz Channel 05 2420.330 MHz Channel 10 2440.310MHz Channel 09 2436.330 MHz Channel 06 2424.310 MHz Channel 16 2468.320MHz Channel 18 2476.350 MHz Channel 07 2428.310 MHz Channel 05 2420.330MHz Channel 10 2440.310 MHz Channel 08 2432.310 MHz Channel 12 2448.320MHz Channel 01 2404.320 MHz Channel 09 2436.330 MHz Channel 18 2476.350MHz Channel 11 2444.320 MHz Channel 10 2440.310 MHz Channel 07 2428.310MHz Channel 02 2408.300 MHz Channel 11 2444.320 MHz Channel 13 2456.310MHz Channel 12 2448.320 MHz Channel 12 2448.320 MHz Channel 02 2408.300MHz Channel 03 2412.310 MHz Channel 13 2456.310 MHz Channel 09 2436.330MHz Channel 04 2416.290 MHz Channel 14 2460.330 MHz Channel 15 2464.340MHz Channel 13 2456.310 MHz Channel 15 2464.340 MHz Channel 04 2416.290MHz Channel 05 2420.330 MHz Channel 16 2468.320 MHz Channel 11 2444.320MHz Channel 14 2460.330 MHz Channel 17 2472.350 MHz Channel 17 2472.350MHz Channel 06 2424.310 MHz Channel 18 2476.350 MHz Channel 062424.310MHz Channel 15 2464.340 MHz The sequences are generated by Matlab RAND function in which calculate uniformly distributed random numbers. The first 18 channels are grouped into Sequence 1. Sequence 2 is generated by the same function with only the same 18 channels are selected (in different order). Equal Hopping Frequency Use Describe how each individual EUT meets the requirement that each of its hopping channels is used equally on average (e.g., that each new transmission event begins on the next channel in the hopping sequence after the final channel used in the previous transmission event). In a clean RF environment, which means few or no other RF transmitters nearby, the nRF24Z1 will use all the channels in hopping table. FCC ID: AAO3301253T 1 A synchronized frequency hopping table is kept in the ARX by use of the service channel superimposed on the audio stream. In summary: All channels will on average be used equally. Thop depends on the audio rate, you can find values below: Fs=44.1kHz : Thop=2.9ms System Receiver Input Bandwidth Describe how the associated receiver(s) complies with the requirement that its input bandwidth (either RF or IF) matches the bandwidth of the transmitted signal. It's the same RF device, the only difference is that one is set as a transmitter and the other in receive mode. Main data stream is one-way audio, which is why they are referred to as a transmitter and receiver. The receiver bandwidth is 4000kHz where the 20dB bandwidth of transmitter is 2450kHz. System Receiver Hopping Capability Describe how the associated receiver(s) has the ability to shift frequencies in synchronization with the transmitted signals. A two-way low speed data and control channel makes it possible to exchange information. The ARX will start every frame with a ACK on new channel, the ACK will also contain the next 8 channels to use in the hopping scheme. This way even if a ACK is lost, both devices will know which channels to use next. Section 15.247(h) Describe how the EUT complies with the requirement that it not have the ability to be coordinated with other FHSS systems in an effort to avoid the simultaneous occupancy of individual hopping frequencies by multiple transmitters Since the banning list was disabled. So our device does not have the ability to be coordinated with other FHSS systems in an effort to avoid the simultaneous occupancy of individual hopping frequencies by multiple transmitters. Moreover, our device has a unique user ID for link registration. So no other FHSS system can join the link with our device. FCC ID: AAO3301253T 2 FCC ID: AAO3301253T 3 Data frame structure: Each ATX frame consist of 8 packets. Each packets will have - 1 byte preamble - 9 bytes address and control data - 64 bytes audio data - 2 bytes CRC Each ARX acknowledge packet consist of - 1 byte preamble - 27 bytes address and control data - 2 bytes CRC All bits are "ON" in the worst case for both ATX and ARX. ATX 1. The maximum transmitting time is 1.32ms and it is fixed. 2. One frame in each hop and carry a fixed number of frame. ARX 1. The maximum transmitting time is 164us and it is fixed. 2. One frame in each hop and carry a fixed number of frame. Remarks Only one frame will be transmitted in each hop and the hopping time is 2.9ms which is mentioned as above. The transmitter (dongle unit) will waiting the acknowledge packet from the receiver (headphone unit) after the frame transmitted.

INTERTEK TESTING SERVICES FCC ID: AAO3301253T RF exposure For Specific Absorption Rate (SAR) evaluation of the transmitter, with reference to TCB Exclusions List revised on July 17, 2002, portable transmitters with output power less than low threshold and operating within 2.5cm from person’s body can be certified by TCB without the SAR evaluation. The output power for portable transmitters is defined as the higher of the conducted or radiated (EIRP) source- based time averaging output power. And the low threshold is equal to (60/f GHz ) mW for d < 2.5cm, where f GHz is mid-band frequency in GHz, and d is the distance from the portable transmitter to a person’s body, excluding hands, wrists, feet, and ankles. For the transmitter of the tested model of 33-1253, the measured peak conducted power was 1.28 mW. The maximum source-based time averaging duty factor in 45.5172%. The conducted source-based time averaging output power = (1.28 * 0.45517) mW = 0.58262 mW The measured maximum field strength (FS) was 103.2 dBμV/m. The distance (D) between the antenna and the equipment under test (EUT) was 3 meters. From these data, the radiated (EIRP) source-based time-averaging output power can be calculated by: The radiated power = (FS*D) 2 / 30 mW = 6.2679 mW The radiated (EIRP) source-based time-averaging output power = (6.2679 * 0.45517) mW = 2.85296 mW The low threshold in the 2400-2483.5 band is 24.57 mW. From the above calculation, output power obtained in both method is less than low threshold, it is concluded that the transmitter can be certified by TCB without the SAR evaluation.
