The ATA5743 is a multi-chip PLL receiver device supplied in an SSO20 package. It has been especially developed for the demands of RF low-cost data transmission systems with data rates from 1 kBaud to 10 kBaud in Manchester or Bi-phase code. The receiver is well suited to operate with Atmel's PLL RF transmitter U2741B. 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 = 300 MHz to 450 MHz for ASK or FSK data transmission. All the statements made below refer to MHz and 315 MHz applications.
