TSW3065EVM – Standalone LO Source
This document describes the steps to properly operate and understand the TSW3065EVM Evaluation
Module. TSW3065EVM eliminates expensive signal generators and also acts as a demo enabler for TI
solutions such as, TSW3725, TSW6011, GC5330, GC5325, etc. TSW3065EVM can be used as
standalone source as the dip switch enables no GUI usage with four significant pre-programmed
frequencies, and the GUI can be enabled for detailed control. It can either be powered up with a 6-V DC
adaptor supply or 5-V DC USB supply from a laptop/computer. It operates from 300 MHz to 4.8 GHz and
provides output power more than 15 dBm up to 2.7 GHz.

1 Overview
TSW3065EVM is based on Texas Instruments integer-N / Fractional –N frequency synthesizer with
integrated wideband VCO TRF3765. Its frequency ranges from 300 MHz to 4.8 GHz. It provides
programmable output power with a combination of amplifier and programmable attenuator. TSW3065EVM
has an option of on-board or off-board reference selection. The on-board reference is from 10 MHz
crystal.
