Description

TRF3761 is a family of high performance, highly integrated frequency synthesizers, optimized for high performance applications. The TRF3761 includes a low-noise, voltage-controlled oscillator (VCO) and an integer-N PLL.

TRF3761 integrates divide-by 1, 2, or 4 options for a more flexible output frequency range. It is controlled through a 3-wire serial-programming-interface (SPI) interface. For power sensitive applications the TRF3761 can be powered down by the SPI interface or externally via chip_en pin 2.
