  • AN-00310 - Encoder and Decoder Comparison
    Encoders and decoders are an ideal way of sending on / off data, such as button presses, to a remote location. When a line on the encoder is taken high, it will create a data stream that is sent to the decoder. The decoder will interpret the data stream and take a corresponding data line high
  • H.265 is Coming. What Will This Mean for Encode and Decode Engines?
    H.265 is coming. What will this mean for encode and decode engines?
  • KEELOQ (R) Code Hopping Decoder Using a PIC16C56
    This application note fully describes the working of a code hopping decoder implemented on a Microchip PIC16C56 microcontroller. Background is given on the various KEELOQ (R) code hopping encoders that can be used with the decoder, the decoder hardware described, and descriptions of the various
  • KEELOQ (R) Simple Code Hopping Decoder
    This application note fully describes the working of a code hopping decoder implemented on a Microchip PIC16C54 microcontroller. The PIC16C54 is smaller than the PIC16C56 used in the normal decoder (AN642) or the secure learn decoder (AN652). A sim-plified learning scheme with all encoders sharing
  • KEELOQ Code Hopping Decoder Using Secure Learn
    part of the transmission, principally containing the encoder's serial number identifying it to a decoder. The hopping code contains function information, a discrimination value, and a synchronization counter. This information is encrypted by an encryption algorithm before being transmitted. A 64-bit
  • How Does an Optical Encoder Work?
    The Optical Encoders typically consist of a rotating and a stationary member. The rotor is usually a metal, glass, or a plastic disc mounted on the encoder shaft. The disc has some kind of optical pattern, which is electronically decoded to generate position information. The rotor disc in absolute
  • AN-00156 - Reading The Tx ID From the MS And HS Decoders
    The Linx MS and HS Series of decoders have the. ability to output a number that uniquely identifies the encoder that sent the transmission. This can be used to log access attempts or in any application where the originating transmitter needs to be known. This application note will discuss how
  • Secure Learning RKE Systems Using Encoders
    Learning capability in remote keyless entry (RKE) and remote-controlled security systems is regarded as essential by most manufacturers. The logistical problems associated with the supply of replacement and additional transmitters for personalized decoders quickly become overwhelming if any dealer
