1. Description

The ATA5760/ATA5761 is a multi-chip PLL receiver device supplied in an SO20 pack-

age. 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 the Atmel’s PLL RF trans-

mitter 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 f

transmission. All the statements made below refer to 868.3 MHz and 915.0 MHz

applications.
