TDA5225 - Infineon Technologies

Überblick

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

Zusammenfassung der Merkmale

Highest sensitivity receiver: Typ. -118 dBm for FSK Typ. -116 dBm for ASK
Autonomous receive mode leads to reduced noise of host processor, improved sensitivity and reduced power consumption of the system
Up to 4 (TDA5240)/ 2 (TDA5235) parallel parameter sets and up to 12 different
frequency channels(TDA5240 only)
Several embedded encodings and modulation schemes
Ultrafast Fallback Wake-up criterion reduces receiver’s active time, when no data available
