- **Operating Temperature Range:** -40°C to +85°C  
- **RF Input Impedance:** 75 Ω (single-ended)  
- **Gain Control Range:** >90 dB (automatic gain control)  
- **IF Output:** Zero-IF (I/Q baseband outputs)  
- **Integrated Features:**  
  - On-chip PLL with VCO  
  - Integrated RF and baseband filters  
  - I/Q demodulator  

### **Descriptions:**  
The MAX2117CTI+T is a direct-conversion tuner optimized for digital TV standards (DVB-T, DVB-H, ISDB-T, ATSC, etc.). It eliminates the need for external SAW filters and IF circuitry by directly converting RF signals to baseband I/Q outputs.  

### **Features:**  
- **Low Power Consumption:** Optimized for portable applications.  
- **High Integration:** Includes PLL, VCO, LNA, mixers, and baseband filters.  
- **Wideband Operation:** Supports global TV standards.  
- **Automatic Gain Control (AGC):** Ensures stable signal reception.  
- **Single 3.3V Supply:** Simplified power management.  
- **I²C Interface:** For digital control and configuration.  

This device is suitable for set-top boxes, mobile TV receivers, and other digital TV tuner applications.
