Description and Introduction

FM radio + RDS The TEA5764HN is a low-power FM stereo radio chip manufactured by NXP Semiconductors. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Frequency Range:** 76–108 MHz (covers Japan, Europe, and US bands)  
- **Supply Voltage:** 2.5V to 5.5V  
- **Current Consumption:** Low-power operation (typically 6 mA in stereo mode)  
- **Tuning Step:** Adjustable (50 kHz, 100 kHz, 200 kHz)  
- **Signal-to-Noise Ratio (SNR):** ≥ 60 dB (mono)  
- **Total Harmonic Distortion (THD):** ≤ 0.3% (mono)  
- **IF Frequency:** 225 kHz (low-IF architecture)  
- **Package:** HVQFN32 (5x5 mm)  

### **Descriptions:**  
- The TEA5764HN is an integrated FM radio receiver with a digital low-IF architecture, eliminating the need for external IF filters.  
- It supports both mono and stereo FM reception with automatic switching.  
- The chip includes an on-chip phase-locked loop (PLL) for precise tuning.  
- It features I²C-bus control for easy integration with microcontrollers.  

### **Features:**  
- **Low-IF Digital Tuning:** Reduces external component count.  
- **Automatic Gain Control (AGC):** Ensures stable reception under varying signal conditions.  
- **Soft Mute:** Minimizes noise during weak signal reception.  
- **Stereo/Mono Switching:** Automatic or manual control.  
- **Standby Mode:** Reduces power consumption when inactive.  
- **Integrated Audio Output:** Supports direct connection to headphones or amplifiers.  

This information is based on NXP's official documentation for the TEA5764HN.
