Description and Introduction

Complete DBS Direct-Conversion Tuner ICs with Monolithic VCOs The MAX2118UTL is a highly integrated, direct-conversion tuner IC designed for digital TV applications.  

### **Manufacturer:** Maxim Integrated (now part of Analog Devices)  

### **Specifications:**  
- **Frequency Range:** 48 MHz to 860 MHz  
- **Input Signal Level:** -85 dBm to +5 dBm  
- **Noise Figure:** 4.5 dB (typical)  
- **Gain Control Range:** 90 dB (typical)  
- **Supply Voltage:** 3.3 V  
- **Current Consumption:** 120 mA (typical)  
- **Package:** 56-pin TQFN (Thin Quad Flat No-Lead)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX2118UTL is a zero-IF (ZIF) tuner that converts RF signals directly to baseband I/Q outputs, eliminating the need for external SAW filters. It integrates an RF amplifier, mixer, VCO (Voltage-Controlled Oscillator), PLL (Phase-Locked Loop), and baseband amplifiers, making it suitable for digital TV, cable, and terrestrial applications.  

### **Features:**  
- **Direct Conversion Tuner:** Eliminates IF stage, reducing external components.  
- **Integrated PLL and VCO:** Supports fractional-N synthesis for precise frequency tuning.  
- **High Linearity:** Supports high-performance digital TV reception.  
- **Low Noise Figure:** Ensures good sensitivity.  
- **I/Q Baseband Outputs:** Provides differential outputs for direct ADC interfacing.  
- **Digital Gain Control:** Allows precise signal level adjustment.  
- **Single 3.3V Supply:** Simplifies power supply design.
