The TRF3761-CIRHAT from Texas Instruments is a high-performance, highly integrated frequency synthesizer designed for demanding applications. It features an Integer-N PLL architecture combined with a low-noise, voltage-controlled oscillator (VCO).
Key electrical specifications include an operating frequency range from 1.66 GHz to 1.79 GHz, with a typical normalized PLL phase noise of -137 dBc/Hz at a 600kHz offset and a low noise floor of -158 dBc/Hz at a 10MHz offset. The device operates from a single supply voltage of 4.5V to 5.25V and has a typical current consumption of 130 mA. It supports input reference frequencies from 10 MHz to 104 MHz and integrates divide-by 1, 2, or 4 options for flexible output frequency generation.
This synthesizer is housed in a 40-VQFN (6x6 mm) package suitable for surface mounting. The operating temperature range is -40°C to 85°C. Control is managed via a 3-wire serial programming interface (SPI), and the device includes hardware and software power-down capabilities. The TRF3761 family is optimized for high-performance applications requiring precise frequency synthesis.
