Control124
4 bit Address - 12 bit Data encoder/decoder
Control124 is a 4 bit address, 12 bit data encoder and decoder combined in a single IC. This device can operate in either Encode or Decode mode. It uses 1kbps differential Manchester bit balancing with preamble and checksum. CTR124 is specifically designed to be used in RF remote control applications. It is available in 28pin SO and DIL packages.

Features
Operating voltage (temperature): 4.0V-5.5V for standard version (-40°C to +125°C) 2.0V-5.5V for low voltage version (-40°C to +85°C) Draws <2mA without external load 4 bit address and 12 bit data 16 different remotes with 12 controls each Single packetised transmission for fast activation Maximum usage of the range capability of an RF module Adequate preamble to settle data slicer in the receiver. Extra wake up preamble to allow for transmitter power up time requirements Differential Manchester encoding of address, data and checksum Synchronisation codes and checksum to reduce false triggering on noise Suitable to be used with Narrow Band FM radio modules Ceramic resonator or crystal oscillator up to 20MHz Data rate up to 5.6kbps Minimum external component requirement 4 wire, push button and latched push button modes Custom address, data bit variations availabl……
