It has been specially developed for the demands of RF low-cost data transmission systems with data rates from 1 kBaud to 10 kBaud 1 kBaud to kBaud for FSK in Manchester or Bi-phase code. The receiver is well-suited to operate with PLL RF transmitter IC U2741B. Its main applications in the area of wireless control are telemetering, security technology, tire-pressure monitoring and keyless-entry systems. It can be used in the frequency receiving range of f0 = 300 MHz to 450 MHz for ASK or FSK data transmission. All the statements made in this datasheet refer both to MHz and 315 MHz applications.
