ATA3742

Features IC Distinguishes the Signal Strength of Several Transmitters via RSSI (Received Signal Strength Indicator) Output 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) High Image Frequency Suppression Due to 1 MHz IF in Conjunction With a SAW Front-end Filter (Up to 40 dB Achievable With Newer SAWs) Communication to Microcontroller Possible via a Single, Bi-directional Data Line Power Management (Polling) is also Possible by Means of a Separate Pin via the Microcontroller UHF ASK/FSK Receiver ATA3742 www.DataSheet4U.com 1. Description The ATA3742 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 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 to operate with Atmel’s PLL RF transmitter IC U2741B. Its main applications in the area of w...
