high, low, and floating. the data lines will not function unless the address lines share identical states with the encoder address lines. contention considerations an unlimited number of decoder modules may be operated in proximity without interference. it is important, however, to understand that only one transmitter at a time can be activated within a reception area. while the transmitted signal consists of encoded digital data, only one carrier of any frequency can occupy airspace without contention at any given time. page 3 page 2 theory of operation the fctn-dec1-xxx decoder module combines the popular linx lc series receiver with a decoder ic and ra series antenna in a convenient through-hole package. when transmitted data is received, the data is presented to the decoder. the decoder detects the logic states of the address lines. if these match with the address settings of the transmitter, the decoders output(s) are set to replicate the state of the transmitter?s data lines. output pin considerations the output pins will normally require buffering due to their low sink or source current capability. the external addition of a transistor or other buffer is recommended to provide the appropriate sink or source current for devices such as relays, led?s or motors. power supply requirements the user must provide a clean source of power to the module to ensure proper operation. power-supply noise will manifest itself as am and fm noise and can significantly affect transceiver performance. providing a clean power supply for the module should be a high design priority. the module?s power-supply line should have bypass capacitors configured as shown. actual capacitor values will vary depending on noise conditions. layout considerations a 1/4 wave antenna such as that employed on the fctn-dec1-xxx utilizes the groundplane as the antenna's counterpoise. in order to achieve the best range and uniformity, the designer should provide an additional external groundplane. this can be accomplished in several ways, but a ground fill on the product?s pc board will generally suffice. the mounting hole beside the antenna must be tied directly to adequate groundplane no greater than 1/2" away to achieve desired range. .1 f >10 f v cc in v cc to module figure 2: electrical specifications pin# name pin# name 1 address 6 20 address 5 2 address 7 19 address 4 3 address 8 18 address 3 4 data 0 17 address 2 5 vcc 16 address 1 6 data 5 15 address 0 7 data 4 14 data 6 8 data 3 13 data 7 9 data 2 12 valid tx 10 data 1 11 gnd * model dependent
page 5 page 5 typical application for fctn-dec1-xxx page 4 page 4 compliance requirements (instruction manual) for products containing the fctn-dec1-xxx, it is necessary to include the following statement in the end product?s instruction manual or insert card. instr uctions t o the user this equipment has been tested and found to comply with the limits for a class b digital device, pursuant to part i5 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. in order to maintain compliance with fcc regulations, shielded cables must be used with this equipment. operation with non- approved equipment or unshielded cables is likely to result in interference to radio and tv reception. the user is cautioned that changes and modifications made to the equipment without the approval of manufacturer could void the user's authority to operate this equipment. place the above statement in the instruction manual or insert card.
