TDA5240数据手册RF/IF射频/中频RFID的射频接收器规格书PDF

描述 Description

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

特性 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 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

优势:

应用 Application

• Remote keyless entry systems

• Remote start applications

• Tire pressure monitoring

• Remote control units

• Cordless alarm systems

• Remote metering
