TX2/RX2
REMOTE CONTROLLER WITH FIVE FUNCTIONS
General Description
The TX2/RX2 are a pair of CMOS LSIs designed for remote controlled car applications. TX2
Is the transmitter and RX2 is the receiver. They provide five function key to control forward, Backward,
Rightward, Leftward and Turbo motions. Beside,a combination of these five motions can be played.
RX2 Provide two high effective amplifiers and Enhance Signal Input recognition capacity to enhance remote
control distance.
Major Core Features:
! Wide and low operating voltage range: 2.2V to 5.0V
! Typical oscillator frequency:
RF:128KHz.
IR :114KHz(Carrier Frequency:57KHz).
IR : 76KHz(Carrier Frequency:38KHz).
! Provide two transmissive interface(RF and IR)for different application.
! RX2 Provide two high effective amplifiers to enhance remote control distance.
! Enhance Signal Input recognition capacity for very weak signal.
! Auto Power-OFF function for TX2
! Low Standby current (TX2) and low operating current.(RX2).
! Oscillator with an external resistor.
Peripheral Features:
! 5-function remote controller controlling forward/ backward/ turbo/ right/ left.
! Few external components needed.
Application Field:
! remote controlled toy.
! remote electric appliance controller.
