Description and Introduction

N-Channel 150-V (D-S) MOSFET The SI4848DY is a digital CMOS AM/FM/SW radio receiver IC manufactured by Silicon Labs. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Silicon Labs (Now part of Skyworks Solutions, Inc.)  

### **Specifications:**  
- **Frequency Range:**  
  - AM: 520–1710 kHz  
  - FM: 64–108 MHz  
  - SW: 5.6–22 MHz (Shortwave)  
- **Supply Voltage:** 2.7–5.5 V  
- **Current Consumption:**  
  - AM: ~30 mA  
  - FM: ~35 mA  
- **Tuning Steps:**  
  - AM: 1/9/10 kHz  
  - FM: 50/100 kHz  
  - SW: 5 kHz  
- **IF Bandwidth:** Adjustable (3/4/6 kHz for AM, 110/84/60 kHz for FM)  
- **Signal-to-Noise Ratio (SNR):**  
  - AM: >50 dB  
  - FM: >60 dB  
- **Audio Output:** Digital (I2S) and analog (via built-in DAC)  
- **Interface:** I2C (for control)  

### **Descriptions:**  
- The SI4848DY is a fully integrated, low-power AM/FM/SW radio receiver IC.  
- It uses a digital tuning architecture for precise frequency control.  
- No external IF filters or tuning components are required.  
- Supports global broadcast band standards.  

### **Features:**  
- **Digital Tuning:** No manual alignment needed.  
- **Seek and Scan Functions:** Automatic station detection.  
- **RDS/RBDS Support:** (For FM mode, if enabled).  
- **Integrated Audio Processing:** Bass, treble, and volume control.  
- **Low External Component Count:** Reduces BOM cost.  
- **Small Package:** 24-pin SSOP (Shrink Small Outline Package).  

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