The LM1871 is designed as the wireless remote control launch coding circuit that can be used in the electronic toys and model cars. The internal circuit is composed of the channel addition logic circuit, the 4.6V voltage regulator, the encoder, the frame-picture timer and the pulse timer. FeaturesThe IC has the radio frequency oscillator/transmitter and the 4.6V voltage regulator.The RF output power is adjustable.The six proportion channels use the same timing capacitor.The channel number is programmable. The external modulator controls the frequency band width.It can be used in the low power, non-speech signal and unauthorized communication devices with the carrier frequency of 27MHz or 49MHz and the 3m field strength of 10000uV/m.
