Description and Introduction

ASK/FSK Single Conversion Receiver The TDA5221 is a low-power ASK/FSK receiver IC manufactured by Infineon Technologies. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Frequency Range:** 868 MHz to 870 MHz (ISM band)  
- **Modulation:** ASK (Amplitude Shift Keying) and FSK (Frequency Shift Keying)  
- **Supply Voltage:** 2.0V to 3.6V  
- **Current Consumption:**  
  - Standby: 0.3 µA (typical)  
  - Active (RX mode): 5.5 mA (typical)  
- **Sensitivity:** -109 dBm (for ASK, 1 kbps, BER < 0.1%)  
- **Data Rate:** Up to 20 kbps  
- **IF Bandwidth:** Adjustable (315 kHz or 455 kHz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-20  

### **Descriptions:**  
- Designed for low-power wireless applications in the 868 MHz ISM band.  
- Suitable for remote keyless entry (RKE), home automation, and sensor networks.  
- Integrates a low-IF receiver with digital demodulation for improved performance.  
- Supports both ASK and FSK modulation schemes.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **High Sensitivity:** Ensures reliable reception in weak signal conditions.  
- **Integrated Digital Demodulator:** Reduces external component count.  
- **Wake-on-Radio (WOR) Functionality:** Enables ultra-low-power standby mode.  
- **Configurable IF Bandwidth:** Allows flexibility for different data rates.  
- **Automatic Frequency Control (AFC):** Compensates for frequency drift.  
- **RSSI (Received Signal Strength Indicator):** Provides signal strength feedback.  

The TDA5221 is a cost-effective solution for short-range wireless communication with robust performance in noisy environments.
