Description .. The ATA5760/ATA5761 is a multi-chip PLL receiver device supplied in an SO20 package. It has been especially developed for the demands of RF low-cost data transmission systems with data rates from 1 k Baud to 10 k Baud in Manchester or Bi-phase code. The receiver is well suited to operate with the Atmel’s PLL RF transmitter T5750. Its main applications are in the areas of telemetering, security technology and keyless-entry systems. It can be used in the frequency receiving range of f0 = 868 MHz to 870 MHz or f0 = 902 MHz to 928 MHz for ASK or FSK data transmission. All the statements made below refer to 868.3 MHz and 915.0 MHz applications. Figure 1-1.
