Quick-Start Procedure for Digital DDC (Decimation Plus NCO) Mode in ADC32RF4x
and ADC32RF8x

The clock rate in this example is 2.94912 Gsps and is only supported by the ADC32RF45 and
ADC32RF80. For the ADC32RF44, the same steps can be followed, albeit at a lower clock rate (

≤

2.6

Gsps).

5.1

TSW14J56

Follow these steps to use the TSW14J56 with the ADC32RFxx EVM:

1. Connect the ADC32RFxx EVM to the TSW14J56 using the FMC connectors.

2. Connect a 5-V power supply to connector J11 (+5 V IN).

3. Connect a USB cable to the USB connector (J9).

4. Flip the power switch (SW6) to the “ON” position.

5.2

ADC32RFxx EVM

Use the following steps to prepare the ADC32RFxx EVM for use:

1. Verify jumper JP3 is set for position EXT to select external clocking.

2. Connect a 5-V, 3-A power supply to connector J15. Do not use a supply that is rated less than 3 A.

3. Connect a USB cable to the USB connector (J11 on the bottom side of board).

4. Connect an analog RF signal from a signal source to the AINP SMA (J2).

5. Connect a signal generator set for 2.94912 GHz to the external clock input J5.

6. Connect another signal generator set for 2.94912 GHz to the LMK04828 reference clock input J7.

(Make sure the two signal generators for the ADC clock and LMK04828 clock are synchronized to the
same timebase, or use a single signal generator and a splitter to generate two copies of the clock to go
to the EVM.)

Fs = 2.94912 GHz, 8x Decimation Example, External Clocking

This example captures 8× decimated data from channel A of the ADC32RFxx EVM sampling at 2.94912
GHz with a 1960-MHz IF input source.

The ADC requires the device clock and SYSREF signals to be

present before the ADC can be properly configured so the LMK (and optional LMX, if used) setup
must be done before configuring the ADC

.

1. Open the ADC32RFxx EVM GUI.

2. Verify that the green

USB Status

indicator is lit. If it is not lit, click the

Reconnect?

button and check

the

USB Status

indicator again. If it is still not lit then verify the EVM is connected to the computer

through USB. Whenever the USB link is disturbed, the GUI must obtain a new handle to address the
proper USB port, and the

Reconnect?

button does that.
