Product Brief TDA 7210 ASK/FSK Receiver for the 434 and 868 MHz Frequency Band Main Features The TDA 7210 IC is a single chip ASK/FSK Superheterodyne Receiver (SHR) for the 434 and 868 MHz frequency band with very low power consumption. It offers a high level of integration and only a few external components are needed to build a fully functional superheterodyne receiver. Frequency range: 400 to 440MHz, 810 to 870MHz The device contains a low noise amplifier (LNA), a double balanced mixer, a fully integrated VCO, a PLL synthesizer, a crystal oscillator for the reference frequency, a limiter with RSSI generator, a PLL-based FSK demodulator, a data filter, a data comparator (slicer) and a peak detector. ASK and FSK demodulation ASK sensitivity typically -110dBm over specified temperature range (-40 to +85°C) FSK sensitivity typically -103dBm over specified temperature range (-40 to +85°C) Additionally a power - down feature is available, which saves current and extends the battery life. Low supply current Very low supply current in power down mode (50nA typ.) Applications Remote controls Home automation Security and alarm systems Industrial control Low bit-rate communication Supply voltage range 5V ±10% Temperature range -40 to +85°C Fully integrated PLL Synthesizer and VCO (no need for external VCO coils) IF limiter with RSSI generation, centered on 10.7MHz Data filter with external capacitors and integrated resistors (resulting Ordering information Type TDA 7210 in high flexibility by processing Package different data rate) Ordering Code PG-TSSOP-28 SP000524274 Built-in AGC with user-presetable threshold for LNA Low/High gain switch-over Evaluation kit Type Modulation Frequency Ordering Code TDA7110-TDA7210_868_10 ASK/FSK 868 MHz SP000546902 www.infineon.com/receiver Product Brief TDA 7210 ASK/FSK Receiver for the 434 and 868 MHz Frequency Band Target Application Transmitter Receiver High Featured SmartLEWISTM TX TDA 5150 SmartLEWISTM RX TDA 523x MultiChannel Automotive/High Temperature High temperature range Variants for 315, 434, 868 and 915MHz Full automotive qualified Industrial -40 to +85°C 434 and 868MHz ASK and FSK SmartLEWISTM MCU PMA 51xx Benefit from Infineon’s high quality transmitter TDA 520x TDK 510x TDA 521x TDK 511x TDA 522x SmartLEWISTM MCU PMA 71xx TDA 7210–Part of a Comprehensive and Complementary Product Portfolio and receiver product portfolio to find the right and cost effective solution for your application needs.
