T5744

• 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 4.5 V to 5.5 V, 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 Biphase)
• 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

The T5744 is a PLL receiver device for the receiving range of f0 = 300 MHz to450 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 includingManchester, Biphase and most PWM protocols. Its main applications are in the areasof telemetering, security technology and keyless-entry systems.
