ATA3741

Features 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 Supply Voltage 4.5V to 5.5V Operating Temperature Range –40°C to +105°C Single-ended RF Input for Easy Adaptation 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 2 Different IF Bandwidth Versions are Available (300 kHz and 600 kHz) UHF ASK Receiver IC ATA3741 1. Description www.DataSheet4U.com The ATA3741 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 (1 kBaud to 3.2 kBaud for FSK) in Manchester or Bi-phase code. The receiver is well-suited...
