ATA3742 UHF ASK/FSK Receiver

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.
