Description and Introduction

Complete DBS Direct-Conversion Tuner ICs with Monolithic VCOs The MAX2116UTL is a highly integrated, direct-conversion tuner IC designed for digital TV applications. Below are the factual details from Ic-phoenix technical data files:

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

### **Specifications:**  
- **Type:** Direct-Conversion Tuner IC  
- **Package:** 40-Pin TQFN (Thin Quad Flat No-Lead)  
- **Operating Voltage:** 3.3V  
- **Frequency Range:**  
  - RF Input: 48MHz to 860MHz  
  - IF Output: DC to 8MHz  
- **Gain Control:**  
  - Automatic Gain Control (AGC)  
  - Programmable RF and Baseband Gain  
- **Noise Figure:** Typically 5dB  
- **Input IP3 (Third-Order Intercept Point):** Typically +5dBm  
- **Power Consumption:** Typically 650mW  
- **Integrated Features:**  
  - On-chip VCO (Voltage-Controlled Oscillator)  
  - Fractional-N Synthesizer  
  - I/Q Demodulator  
  - Low-Noise Amplifier (LNA)  
  - Mixers and Baseband Filters  

### **Descriptions:**  
- The MAX2116UTL is a zero-IF (ZIF) tuner designed for digital TV standards such as DVB-T, DVB-H, ISDB-T, and ATSC.  
- It integrates RF front-end, downconversion, and baseband processing into a single chip, reducing external component count.  
- Supports both single-ended and differential RF inputs.  
- Features an SPI-compatible interface for digital control.  

### **Features:**  
1. **Direct Conversion Architecture:** Eliminates the need for external SAW filters and IF stages.  
2. **Integrated Synthesizer:** Reduces phase noise and improves tuning accuracy.  
3. **High Linearity:** Supports strong adjacent-channel rejection.  
4. **Low Power Consumption:** Optimized for portable and set-top box applications.  
5. **Flexible AGC:** Adjustable RF and baseband gain for optimal signal handling.  
6. **Single 3.3V Supply:** Simplifies power management.  

This information is strictly based on the available technical data for the MAX2116UTL.

Application Scenarios & Design Considerations

Alternative Part Number

  • LT5516EUF --: Direct functional equivalent: wideband active mixer/downconverter covering a similar RF range with comparable gain and linearity, suitable as a drop-in alternative in receiver front-ends.
  • AD8343ACPZ --: High-performance active mixer with similar frequency coverage and conversion gain, widely used as a second-source option for MAX2116-class downconverter designs.
  • HMC688LP4E --: Integrated mixer/IF amplifier in a compact package offering comparable performance for the same application class, useful when the MAX2116 is unavailable.
  • ADL5350ACPZ --: Wideband active mixer with comparable conversion gain and linearity, commonly used as an alternative to Maxim downconverter mixers in the same applications.
