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
SSO20 and SO20 package
Fully Integrated VCO
Supply Voltage 4.5V to 5.5V, Operating Temperature Range –40°C to
+105°C
Single-ended RF Input for Easy Adaptation to l/4 Antenna or Printed
Antenna on PCB
Low-cost Solution Due to High Integration Level
Various Types of Protocols Supported (i.e., PWM, Manchester and
Bi-phase)
Distinguishes the Signal Strength of Several Transmitters via RSSI (Received Signal
Strength Indicator)
ESD Protection According to MIL-STD. 883 (4KV 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
Power Management (Polling) is Possible by Means of a Separate Pin via the
Microcontroller
Receiving Bandwidth BIF = 600 kHz
1.
The ATA5744 is a PLL receiver device for the receiving range of f
0
= 300 MHz to
450 MHz. It is developed for the demands of RF low-cost data communication sys-
tems with low data rates and fits for most types of modulation schemes including
Manchester, Bi-phase and most PWM protocols. Its main applications are in the areas
of telemetering, security technology and keyless-entry systems.
