Setup Procedure
2.5
Connect the Signal Generators to the EVM (*RF Outputs Disabled Until Directed)
Connect a signal generator to the VIN input of the ADC12DL3200EVM through a bandpass filter and
attenuator at the SMA connector. This must be a low-noise signal generator. TI recommends a Trilithic-
tunable bandpass filter to filter the signal from the generator. Configure the signal generator for 1910 MHz,
0 dBm.
2.5.1 If External Clocking is Used (Optional)
Connect a signal generator to the DEVCLK input of the EVM through a bandpass filter. This signal
generator must be a low-noise signal generator. TI recommends a Trilithic-tunable bandpass filter to filter
the signal coming from the generator. Configure the signal generator for the desired clock frequency in the
range of 0.8 to 3.2 GHz. For best performance when using an RF signal generator, the power input to the
CLK SMA connector must be 9 dBm (2.2 Vpp into 50
Ω
). The signal generator must increase above 9 dB
by an amount equal to any additional attenuation in the clock signal path, such as the insertion loss of the
bandpass filter. For example, if the filter insertion loss is 2 dB, the signal generator must be set to 9 dBm +
2 dB = 11 dBm.
2.6
Turn On the TSW14DL3200EVM Power and Connect to the PC
1. Turn on the 12-V power supply connected to the TSW14DL3200EVM.
2. Turn on the power switch on the TSW14DL3200EVM.
3. Connect a mini USB 3.0 cable from the PC to the TSW14DL3200EVM.
4. If this is the first time connecting the TSW14DL3200EVM to the PC, follow the on-screen instructions
to automatically install the device drivers. See the
for specific
instructions.
2.7
Turn On the ADC12DL3200EVM 5-V Power Supply and Connect to the PC
1. Turn on the 5-V power supply to power up the EVM.
2. Connect the EVM to the PC with the mini USB cable.
2.8
Turn On the Signal Generator RF Outputs
Turn on the RF signal output of the signal generator connected to VIN. If external clocking is used, turn on
the RF signal outputs connected to DEVCLK and LMKCLK.
