Description and Introduction

ISDB-T/DVB-T Diversity Tuner The MAX2135AETN+ is a high-performance, low-power direct conversion tuner IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX2135AETN+  
- **Package:** 56-Pin TQFN (Thin Quad Flat No-Lead)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage:** 1.8V to 3.3V  
- **Power Consumption:** Low power operation (exact value depends on mode)  
- **Frequency Range:** Covers VHF, UHF, and L-band frequencies (specific range depends on application)  
- **Interface:** I²C-compatible control interface  

### **Descriptions:**  
The MAX2135AETN+ is a direct conversion tuner designed for digital TV and set-top box applications. It integrates a high-performance RF front-end with a direct conversion architecture, eliminating the need for external IF filters. It supports multiple global standards, including DVB-T, DVB-T2, ISDB-T, and ATSC.

### **Features:**  
- **Direct Conversion Architecture:** Eliminates the need for IF SAW filters.  
- **Integrated RF Tracking Filters:** Reduces external component count.  
- **Low Noise Figure:** Ensures high sensitivity.  
- **High Linearity:** Supports robust performance in crowded RF environments.  
- **Programmable Gain Control (PGC):** Adjustable for optimal signal reception.  
- **Integrated VCO and PLL:** Provides precise frequency synthesis.  
- **I²C Control Interface:** Simplifies digital control and configuration.  
- **Low Power Consumption:** Suitable for battery-powered and portable devices.  

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

Application Scenarios & Design Considerations

ISDB-T/DVB-T Diversity Tuner

Alternative Part Number

  • SI4825-A10-CS --: AM/FM receiver IC with integrated tuner covering similar broadcast bands, usable as a functional substitute in radio receiver designs.
  • TEF6686HN/V102 --: Single-chip AM/FM car radio tuner with comparable functionality and digital interface, suitable for similar receiver applications.
  • STA709 --: Automotive AM/FM tuner and audio processor offering similar broadcast reception capability for infotainment designs.
  • MAX2135ETN+ --: Same MAX2135 series with identical pinout and function, differing only in a minor grade variant, so it is a near drop-in replacement.
  • MAX2135CAI+ --: Same MAX2135 family in a different package option; electrically compatible when the board layout supports the alternate footprint.
  • MAX2135EAI+ --: Another MAX2135 series variant with equivalent core specifications, usable as a functional substitute after confirming package and temperature grade.
