It sounds like a contradictory combination, yet this is what is more and more requested from your receiver design: long range, low energy consumption and flexible adaptation to customer requirements. You think this requires high development effort and expensive additional components in your design? Not with our new high sensitivity, low-power receiver family SmartLEWIS RX+. The SmartLEWIS RX+ family consisting of TDA5240, TDA5235 and TDA5225 covers all those requirements with a minimum of external components.
Flexibility
● Multi-band, multi-channel receiver
● Extremely low software development efforts especially with TDA5240/ TDA5235
● Multi-protocol handling
● Only one device for multiple applications (RKE+TPMS+Remote start)
● Complementary product portfolio with Infineon`s transmitters and upcoming transceiver family
Low Cost
● Reduced bill of material through highest integration
● Integrated LNA to achieve high sensitivity
● Internal IF filter (optional usage of external filter possible)
● Minimum external component count
● Optimized product family to offer best cost-feature-ratio
Summary of Features
● Highest sensitivity receiver :Typ. -118 dBm for FSK :Typ. -116 dBm for ASK
● Autonomous receive mode leads to reduced noise of host processor, improved

1 Product Description
1.1 Overview
TDA5235XUMA1 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-phasemark, bi-phase space and differential Manchester are supported.
The chip offers best-in-class sensitivity performance at a very high level of integrationand needs only a few external components.
TDA5235XUMA1 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.
TDA5235XUMA1 receiver is realized as a double down conversion super-heterodyne/low-IFarchitecture each with image rejection supplemented by digital signal processing in thebaseband. A fully integrated Sigma-Delta Fractional-N PLL Synthesizer allows for highresolution frequency generation and uses a crystal oscillator as the reference. The onchip temperature sensor may be utilized for temperature drift compensation via the crystal oscillator.
The digital baseband processing unit together with the high performance down converter is the key element for the exceptional sensitivity performance of the device which take it close to the theoretical top-performance limits. It comprises signal and noise detectors, matched data filter, clock and data recovery, data slicer and a format decoder. It
demodulates the received ASK or FSK data stream independently and recovers the data clock out of the received data stream with very fast synchronization times which can then be either accessed via separate pins or used for further processing like frame synchronization and intermediate storage in the on-chip FIFO. The RSSI output signal is converted to the digital domain with an ADC. All these signals are accessible via the 4-wire SPI interface bus. Up to 2 pre-configured telegram formats can be stored into the device offering independent pre-processing of the received data to an extent not available till now. The down converter can be also configured in single-conversion mode at moderately reduced selectivity performance but at the advantage of omitting the IF ceramic filter.
