Features
Supply Voltage 4.5V to 5.5V Operating Temperature Range –40°C to +85°C Minimal External Circuitry Requirements, No RF Components on the PC Board Except
Matching to the Receiver Antenna High Sensitivity, Especially at Low Data Rates Sensitivity Reduction Possible Even While Receiving Fully Integrated VCO Low Power Consumption Due to Configurable Self-polling with a Programmable Time Frame Check Single-ended RF Input for Easy Matching to λ / 4 Antenna or Printed Antenna on PCB Low-cost Solution Due to High Integration Level ESD Protection According to MIL-STD 883 (4 KV HBM) Except Pin POUT (2 KV HBM) High Image Frequency Suppression Due to 1 MHz IF in Conjunction With a SAW Front-end Filter. Up to 40 dB is Thereby Achievable With Newer SAWs Programmable Output Port for Sensitivity Selection or for Controlling External Periphery Communication to the Microcontroller Possible via a Single, Bi-directional Data Line Power Management (Polling) is also Possible by Means of a Separate Pin via the Microcontroller

1. Description
The ATA3745 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 low 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 ATA2745. It can be used in the frequency receiving range of f0 =...
