1.
The ATA3742 is a multi-chip PLL receiver device supplied in an SO20 package. 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 3.2 kBaud for FSK) in
Manchester or Bi-phase code. The receiver is well-suited to operate with Atmel’s PLL
RF transmitter IC U2741B. Its main applications in the area of wireless control are
telemetering, security technology, tire-pressure monitoring and keyless-entry sys-
tems. It can be used in the frequency receiving range of f
0
= 300 MHz to 450 MHz for
ASK or FSK data transmission. All the statements made in this datasheet refer both to
433.92 MHz and 315 MHz applications.
