Description and Introduction

Wideband I/Q Modulator with Sigma-Delta Fractional-N Synthesizer The MAX2150ETI+ is a highly integrated, silicon tuner IC designed for digital TV applications. Manufactured by Maxim Integrated (now part of Analog Devices), it supports multiple digital TV standards, including DVB-T, DVB-H, ISDB-T, and T-DMB.  

### **Specifications:**  
- **Frequency Range:** 48 MHz to 860 MHz  
- **Supply Voltage:** 1.71 V to 1.89 V (core), 2.7 V to 3.6 V (I/O)  
- **Current Consumption:** 85 mA (typical)  
- **Package:** 28-pin TQFN (7mm x 7mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Signal Level:** -85 dBm to +5 dBm  
- **Noise Figure:** 5 dB (typical)  
- **Gain Control Range:** 90 dB (typical)  

### **Descriptions:**  
The MAX2150ETI+ integrates a low-noise amplifier (LNA), mixer, voltage-controlled oscillator (VCO), phase-locked loop (PLL), and baseband filters, reducing the need for external components. It supports direct conversion (zero-IF) architecture, simplifying receiver design for digital TV tuners.  

### **Features:**  
- **Highly Integrated Tuner:** Combines RF and baseband functions in a single chip.  
- **Low Power Consumption:** Optimized for portable and battery-powered devices.  
- **Wide Frequency Range:** Covers VHF and UHF bands.  
- **Digital I²C Control Interface:** Allows easy configuration.  
- **Automatic Gain Control (AGC):** Ensures stable signal reception.  
- **Low Phase Noise:** Improves demodulation performance.  
- **Small Footprint:** Suitable for space-constrained designs.  

This IC is commonly used in digital TV receivers, set-top boxes, and mobile TV applications.
