TRF3761-JIRHAR TI Fractional-N PLL | 40-VQFN (6x6) | 3.0V, 3.3V, 5V

Product Overview

The TRF3761-JIRHAR is a high-performance fractional-N frequency synthesizer from Texas Instruments, designed for demanding RF applications. It integrates a low-noise phase-locked loop (PLL) with a voltage-controlled oscillator (VCO) and supports a wide frequency range from 0.3 GHz to 4.0 GHz. The device operates from a single 3.0V, 3.3V, or 5V supply and is housed in a compact 40-pin VQFN (6x6 mm) package. Its advanced architecture delivers exceptional phase noise performance and fast settling times, making it ideal for wireless infrastructure, test equipment, and communication systems.
