TRF3765IRHBR TI PLL/VCO | 32-VQFN (5x5) | 3.0-4.4GHz, Low Phase Noise

Product Overview

The TRF3765IRHBR from Texas Instruments is a high-performance, fully integrated fractional-N phase-locked loop (PLL) and voltage-controlled oscillator (VCO) designed for demanding wireless infrastructure and test equipment applications. Operating from 3.0 to 4.4 GHz, this device delivers exceptional phase noise performance of -110 dBc/Hz at 10 kHz offset (3.6 GHz carrier) and -153 dBc/Hz at 1 MHz offset. The integrated VCO eliminates external resonator components, reducing board space and design complexity. The device supports both integer-N and fractional-N modes with a 24-bit modulus for fine frequency resolution. It operates from a single 3.3V supply and features a 3-wire serial interface for programming. The 32-pin VQFN (5x5 mm) package enables compact designs for 5G base stations, microwave backhaul, and software-defined radios.
