IR / 2.4GHz RF Modular Transceiver Installation manual (draft v3) 1. Description This drawing describes an RF / IR remote control transceiver module PCB. The module is part of a panel of PCB’s defined by PT311822 and associated drawings. The module consists of 3 separate circuits : 1) A 2.4GHz RF transceiver IC and etch antenna for use with an RF remote 2) An IR remote control transmitter 3) An IR remote control receiver There is also a pair of LED for indication purposes 2. Cautions: This transceiver module is ONLY to be installed in Bose Corporation devices. 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 Changes or modifications not expressly approved by Bose Corporation could void the user’s authority to operate the equipment.” NOTE: 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.
3. Markings 3.1 This module shall be identified with the following ID numbers on the PCB silkscreen FCC ID : A94311822 IC : 3232A-311822 3.2 End Product Labeling The final end product which this module is used in must be labeled in a visible area with the following: "Contains FCC ID: A94311822 / IC:3232A-311822" 4. Connections The following table describes the connections to the module made via connector J800 Pin # Name Description 1 IR_RCV_DATA IR receiver data output 2 IR_DRIVE IR LED supply 3 +3.3v Power supply 4 CC_DATA_IN RF transceiver IC serial data input 5 GND Ground 6 CC2500_CLCK RF transceiver IC serial clock 7 GND Ground 8 CC_DATA_OUT RF transceiver IC serial data output 9 GND Ground 10 MESSAGE_INT RF transceiver IC interrupt ouput line (to host micro) 11 PWR_RMT_LED2 Red LED (connect to ground via series R to light) 12 CC2500_CS RF transceiver IC chip select 13 PWR_RMT_LED1 Green LED (connect to ground via series R to light) 5. General Electrical specifications 5.1 Power supply 3.3v +/- 5% 5.2 Operational Temperature 0 ~ 45 C (non-condensing) 5.3 Display LED Current 1.3mA typical 5.4 IR Transmitter Current 150mA typical peak
6. 2.4GHz RF Transceiver The RF transceiver uses a TI CC2500 low cost, low power RF transceiver IC to drive a 50 ohm etch antenna via a simple balun and matching network. A switched coaxial connector is provided for test purpose to measure the output power from the IC and balun 6.1 Electrical Specification For a detailed description of the CC2500 and the most recent electrical specification see PT301591-001 (vendor part spec SWRS040C 08_05_04.pdf available on TI web site). The module shall use the following settings : 6.1.1 RF Output Power : +1dBm typical (measured at J801) 6.1.2 Useable Frequency Range: 2401.67 – 2482 MHz 6.1.3 Modulation 250kbaud GFSK with data whitening 6.1.4 Channel Spacing 333kHz 6.2 Antenna Specification The RF module uses an etch antenna whose dimensions and position on the board where determined assuming an ideal ground plane of approximately the dimensions of the actual PCB – as shown below
7. IR Transmitter Refer to PT256733 for detailed electrical specifications of the IR LED’s 8. IR Receiver The module contains 2 IR receiver circuits. These are selected using a GPIO on the CC2500 – controllable via the serial data bus for the IC 8.1 A narrow band (38kHz) IR receiver – Part #319144-038 8.2 A wide band IR receiver constructed from 2 narrow band IR receivers at 38kHz and 56kHz (part # 319144-038 and 319147-156 respectively)
