External Clock Mode DAC38RF82EVM

This section shows how to set up an DAC38RF82EVM using an external clock. This example will
configure the JESD204B DAC in an 841 mode.

Set up the hardware as follows:

1. Connect a 6 GHz, 14-dBm output from a signal generator to DACCLK (J1) of the DAC38RF82EVM.

2. Verify that jumper labeled JP10 is SHUNT 1-2 to enable external clock mode.

3. Connect a power cable to the DAC38RF82EVM and open the DAC38RFXX GUI. The GUI is found

under "Software" on

www.ti.com

featuring the

DAC38RF82EVM

4. On the

Quick Start

tab, toggle

DAC RESETB Pin

and press the

Load Default

button.

5. Configure the GUI as shown in

Figure 26

(a)

DAC Clock Frequency (MHz)

– "6000"

(b)

# of DACs

– "Dual DAC"

(c)

# of IQ pairs per DAC

– "1 IQ pair"

(d)

# of serdes lanes per DAC

– "4 Lanes"

(e)

Desired Interpolation

– "16x"

6. Press the

CONFIGURE DAC

button, then the

PLL AUTO TUNE

button, then the

Reset DAC JESD

Core & SYSREF TRIGGER

button.

7. Navigate to the

LMK04828

tab. Change the

DCLK Divider

CLKout 0 and 1

to "8" as shown in

Figure 27

. This will provide the right reference clock to send to the KCU105.
