Description and Introduction

Complete SDARS Receiver The **MAX2140ETH+T** is a high-performance, low-power, direct conversion tuner IC designed for digital TV applications. Below are the key specifications, descriptions, and features based on the manufacturer's (Maxim Integrated) data:

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

### **Description:**  
The MAX2140ETH+T is a silicon tuner IC optimized for digital TV reception, supporting standards such as DVB-T, DVB-T2, ISDB-T, and ATSC. It integrates a direct conversion architecture, eliminating the need for external SAW filters and reducing component count.  

### **Key Features:**  
- **Frequency Range:** 48 MHz to 860 MHz  
- **Direct Conversion Architecture:** Enables low power consumption and high integration  
- **Low Power Consumption:** Typically 450 mW in active mode  
- **Integrated RF AGC (Automatic Gain Control):** Ensures robust signal reception  
- **Low Noise Figure:** Typically 4.5 dB  
- **High Linearity:** IIP3 of +5 dBm  
- **Single 3.3V Supply Operation**  
- **Integrated VCO (Voltage-Controlled Oscillator) and PLL (Phase-Locked Loop):** Reduces external component requirements  
- **I²C Interface:** For digital control and configuration  
- **Small Package:** 48-pin TQFN (7mm x 7mm)  

### **Applications:**  
- Digital TV set-top boxes  
- USB TV tuners  
- Portable media players  
- PC TV tuner cards
