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
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.

2.1
LO Outputs
TSW3065EVM uses all four LO outputs of TRF3765. Figure 3 shows all the outputs along with ‘Ext VCO
In’ connector.
Figure 3. LO outputs and Ext VCO in
First, ‘LO LF Bal Out’ - SMA output uses a low frequency (900 MHz) balun to one of the four differential
outputs of TRF3765.
Second, ‘LO Amp out’ - the main SMA output, is an amplified single ended line of TRF3765 second LO
output. This chain uses a wide band amplifier and programmable attenuator.
Third, ‘LO HF Bal Out’ - SMA output uses high frequency (1900 MHz) balun to third TRF3765 LO output.
Finally, ‘LO Diff P Out’ and ‘LO Diff M Out’ - SMA outputs are the fourth differential output of TRF3765.
‘Ext VCO In’ - SMA is the external VCO input to TRF3765. Details of these outputs and ‘Ext VCO In’ are
provided in TRF3765 data sheet (SLWS230).
2.2
Supply
A power supply cable and a USB cable have been supplied along with the TSW3065EVM. The
TSW3065EVM can either be powered up with 6-V DC supply or 5-V DC USB supply from laptop/computer
using ‘Supply Select’ switch. When USB powered, the USB version should be either USB 2.0, USB 3.0 or
higher i.e., with 5-V DC and ≥ 500 mA. TSW3065EVM uses Texas Instruments linear regulators
TPS7A8001 and TPS74201, which regulates the supply voltage to 5-V DC (for adaptor supply) / 4.7-V DC
(for USB supply) and 3.3-V DC, respectively. The TSW3065EVM consumes 430 mA of current from a 6-V
supply.
CAUTION
To minimize risk of damage to EVM and/or continued EVM compliance, use
only the power supply provided with this EVM as stated above.
2.3
Reference
TSW3065EVM can be locked either using an on board 10 MHz reference clock or an external 10 MHz, 12
dBm to 13 dBm reference using the ‘Reference Select’ switch. When ‘Ref Select’ switch is at the ‘internal’
position, it selects the internal reference, and when at the ‘external’ position, it selects the external
reference. External reference signal is applied at the ‘Ext Ref’ connector. The reference used to lock
TSW3065EVM is available at the ‘Ref Out’ SMA connector and can be used to lock other devices or
instruments.
2.4
Frequency Selection
The TSW3065EVM has four significant pre-programmed frequencies. These frequencies can be selected
using dip switch. Table 1, shows the positions of dip-switch with LED’s D3, D4, D5, and D6 and respective
programmed frequency. GUI could be used for advanced options or other desired frequency selections.
Whenever the dip switch position is changed to one of the first four settings in Table 1, the respective
frequency registers are loaded after resetting the board (i.e. by pressing ‘Reset’ push button). When the
dip switch position 1111 is selected, the TSW3065EVM is in GUI controlled mode. Figure 4, shows the dip
switch and ‘reset’ push button location.

GUI Details
A TSW3065EVM GUI screen shot is shown in Figure 5. For the board to be GUI controlled, the dip switch
position should be set to 1111. The frequency in the ‘Frequency (Hz)’ tab can be selected from 300 MHz
to 4.8 GHz, and clicking the ‘right’ button enables the selected frequency. The attenuation settings can be
varied from 0 to 31.75, and attenuation up to 30 dB can applied to the ‘LO Amp Out’ signal.
‘LO LF BAL OUT’ can be enable or disabled by turning ON and OFF the LO LF BAL OUT button.
Similarly, others outputs can be turned ON and OFF. Turning ON and OFF ‘LO DIFF OUT’ enables and
disables the ‘LO DIFF P Out’ and ‘LO DIFF M Out’ outputs, respectively. To modify the advance settings
of TRF3765, the ‘TRF3765 Advance Settings’ tab can be used. See the TRF3765 data sheet for TRF3765
detailed settings. As shown in Figure 5, the GUI also displays the TSW3065EVM block diagram.
NOTE:
1. When the TSW3065 GUI is launched, it displays only ‘LO AMP OUT’ turned ON,
but by default at the initial start-up, all the output buffers are turned ON.
2. While operating TSW3065 between 2.06 GHz to 2.18 GHz, always turn OFF
‘LO_LF_BAL_Out’ output buffer.

Setup Steps
Step 1.
To power up the board using a 5 V USB, connect one end of USB (USB2.0, USB3.0 or
higher versions) cable to ‘5V USB In’ and other end to a laptop/computer. Power from the
USB is indicated when the yellow LED ‘D2 USB Supply’ is turned ON. Select the ‘Supply
Select’ switch to the ‘USB’ location as shown in Figure 6. Figure 7(b) shows the
TSW3065EVM setup with USB supply.

Figure 7. TSW3065EVM Setup
Step 3.
Select ‘Ref Select’ switch to ‘Internal’ position as shown in Figure 6. This selects the internal
onboard 10 MHz crystal oscillator as reference. To select an external reference select the
‘Ref Select’ switch to ‘External’ position. This turns on the yellow LED ‘D8 Ext_Ref.’ Apply 10
MHz, 13 dBm of the external reference signal at the ‘Ext Ref In’ connector. ‘Ref Out’ which is
one of the buffered outputs of the reference used to lock TSW3065EVM can be used to lock
other instruments or boards. Figure 7(a) and Figure 7(b) shows TSW3065EVM setup with
internal reference selected.
NOTE: To obtain the best performance, operating the TSW3065 using an internal 10 MHz onboard
crystal is recommended because crystal oscillators usually have a better performance than
laboratory signal generators.
SPACER
Step 4. To use pre-programmed frequencies, select the ‘Freq Select’ dip switch in one of the first four
positions in Table 1 and press ‘Reset' push button. This locks the TSW3065EVM to the
respective frequency of dip switch position and the green LED ‘D1 PLL LOCK’ is turned ON.
Figure 7(b) shows the TSW3065EVM setup in the first dip switch position of Table 1 with D1
turned ON, which indicates TSW3065EVM is locked. To use the board in GUI controlled
mode, turn the dip switch to 1111 position as shown Figure 7(a).

3.2 Canada
3.2.1
For EVMs issued with an Industry Canada Certificate of Conformance to RSS-210
Concerning EVMs Including Radio Transmitters:
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this device must accept any interference, including interference that may
cause undesired operation of the device.
Concernant les EVMs avec appareils radio:
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation
est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit
