Description and Introduction

ASK/FSK 915MHz Single Conversion Receiver The TDA5212 is a low-power ASK/FSK superheterodyne receiver IC manufactured by Infineon (formerly Infineon Technologies). Below are the key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Frequency Range:** 868 MHz / 315 MHz / 433.92 MHz (selectable)  
- **Modulation:** ASK (Amplitude Shift Keying) / FSK (Frequency Shift Keying)  
- **Supply Voltage:** 2.1 V to 3.6 V  
- **Current Consumption:**  
  - Standby Mode: < 1 µA  
  - Operating Mode: ~ 5.5 mA (typical)  
- **Sensitivity:**  
  - ASK: -109 dBm (typical)  
  - FSK: -107 dBm (typical)  
- **IF Frequency:** 1 MHz  
- **Data Rate:** Up to 20 kbps  
- **Package:** P-TSSOP-16  

### **Descriptions:**
- The TDA5212 is designed for low-power wireless applications, such as remote keyless entry (RKE), home automation, and industrial telemetry.  
- It integrates a complete superheterodyne receiver with an on-chip PLL synthesizer, IF amplifier, and demodulator.  
- The IC supports both ASK and FSK modulation schemes, providing flexibility for different wireless communication standards.  
- It features a low-power standby mode, making it suitable for battery-operated devices.  

### **Features:**
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Integrated PLL Synthesizer:** Ensures stable frequency generation.  
- **High Sensitivity:** Enables reliable reception at low signal levels.  
- **Wide Supply Voltage Range:** Operates from 2.1 V to 3.6 V.  
- **Small Footprint:** 16-pin TSSOP package for space-constrained designs.  
- **Wake-up Functionality:** Supports power-saving modes with wake-up capability.  

This information is based solely on the manufacturer's datasheet and technical documentation.
