Description and Introduction

Complete DBS Direct-Conversion Tuner ICs with Monolithic VCOs The MAX2118 is a highly integrated, direct-conversion tuner IC designed for digital TV applications. Here are the key specifications, descriptions, and features from the manufacturer (Maxim Integrated, now part of Analog Devices):

### **Manufacturer:**  
- Maxim Integrated (now Analog Devices)  

### **Description:**  
The MAX2118 is a direct-conversion tuner IC optimized for digital TV reception, supporting standards such as DVB-T, DVB-H, ISDB-T, and T-DMB. It integrates a low-noise amplifier (LNA), mixer, local oscillator (LO), and baseband filters, eliminating the need for an external SAW filter.  

### **Key Features:**  
1. **Frequency Range:**  
   - 48 MHz to 860 MHz (covers VHF and UHF bands).  

2. **Direct Conversion Architecture:**  
   - Eliminates the need for an IF SAW filter, reducing external components.  

3. **Integrated LNA (Low-Noise Amplifier):**  
   - High linearity and low noise figure for improved sensitivity.  

4. **On-Chip PLL and VCO:**  
   - Integrated synthesizer with low phase noise.  

5. **I/Q Demodulation:**  
   - Provides baseband I and Q outputs for digital demodulation.  

6. **Programmable Baseband Filters:**  
   - Adjustable bandwidth to support multiple standards.  

7. **Low Power Consumption:**  
   - Operates from a single 3.3V supply.  

8. **Small Package:**  
   - 48-pin TQFP (Thin Quad Flat Pack) for compact designs.  

9. **Digital Control Interface:**  
   - I²C-compatible interface for easy configuration.  

### **Applications:**  
- Digital TV tuners (DVB-T, DVB-H, ISDB-T, T-DMB).  
- Portable media devices.  
- Set-top boxes.
