TRF3765 Integer/Fractional-N PLL With Integrated VCO
This document describes usage and features of the TRF3765 evaluation module (EVM) for wideband
frequency synthesis applications. The synthesizer uses an integer/fractional-N PLL with integrated VCOs
to generate local oscillator signals from 300 MHz to 4800 MHz. This document describes rapid-start setup
procedures, detailed descriptions of circuit blocks and available options, schematics and printed-circuit
board layout, and a common start-up problem troubleshooting guide.
