Description and Introduction

Low Noise Integer N PLL Frequency Synthesizer With Integrated VCO 40-VQFN -40 to 85 The TRF3761-BIRHAT is a high-performance integer-N synthesizer with an integrated VCO, manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Frequency Range:** 2.25 GHz to 4.5 GHz  
- **Supply Voltage:** 3.3 V  
- **Phase Noise:** Low phase noise performance  
- **Integrated VCO:** Yes  
- **Reference Input Frequency:** Up to 250 MHz  
- **Output Power:** Adjustable  
- **Package:** 40-pin QFN (6 mm × 6 mm)  

### **Descriptions and Features:**  
- **Integer-N PLL with Integrated VCO:** Simplifies RF design by eliminating the need for an external VCO.  
- **Low Phase Noise:** Optimized for high-performance applications.  
- **Programmable Output Power:** Allows flexibility in driving different loads.  
- **Wide Frequency Range:** Supports applications from 2.25 GHz to 4.5 GHz.  
- **Single 3.3V Supply:** Reduces power supply complexity.  
- **High-Speed Phase Frequency Detector (PFD):** Enables fast locking.  
- **40-pin QFN Package:** Compact and suitable for space-constrained designs.  

This device is commonly used in wireless infrastructure, test equipment, and other high-frequency applications.

Application Scenarios & Design Considerations

Low Noise Integer N PLL Frequency Synthesizer With Integrated VCO 40-VQFN -40 to 85

Alternative Part Number

  • LMX2581SQE/NOPB --: Integrated PLL/VCO synthesizer from TI with comparable frequency range and low phase noise, suitable as a functional substitute in many RF synthesis designs.
  • ADF4351BCPZ --: Widely used fractional-N PLL synthesizer with integrated VCO covering a similar frequency band, a common cross-vendor alternative for TRF3761 applications.
  • HMC833LP6GE --: Fractional-N PLL with integrated VCO offering low phase noise and broad frequency coverage, usable as an alternative when TI parts are unavailable.
