Infineon TDA5240XUMA1 RF Receiver, 28-Pin PG-TSSOP-28

The Infineon SmartLEWIS RX+ IC is a low power ASK/FSK Receiver for the frequency bands 300-320, 425-450, 863-870 and 902-928 MHz. Bi-phase modulation schemes, like Manchester, bi-phase mark, bi-phase space and differential Manchester are supported. The chip offers best-in-class sensitivity performance at a very high level of integration and needs only a few external components. The device is qualified to automotive quality standards and operates between -40 and +105°C at supply voltage ranges of 3.0-3.6 Volts or 4.5-5.5 Volts. The receiver is realized as a double down conversion super-heterodyne/low-IF architecture each with image rejection supplemented by digital signal processing in the baseband.
