1. Introduction
1.1 Demoboard overview:
Fig 1. DemoBoard top view
NXP has designed a USB powered demo board to demonstrate the interoperability of
Lattice ECP3 FPGAs with NXP ADC over the JESD204A serial interface.
A single USB cable will allow to supply the board and to communicate with the FPGA &
the ADC thanks to dedicated software running on a PC. It is then possible to load the
data from the ADC through the FPGA and have an overview of the ADC features and
performance, in the frequency range of [0; 30]MHz.
By default an on-board oscillator is used to generate the sampling frequency, but it is
optionally possible to use an external clock to have more flexibility and a better jitter
performance. See Chapter 0 “5.Using an external clock reference”.

1.2 Typical demonstration set-up
Fig 2. Picture of a typical demo set-up
The list of equipment needed is as follows:
A PC
A USB cable
A low jitter sine wave generator
A band-pass filter in case the sine wave is not pure enough
2 SMA-SMA cables if a filter is used, 1 cable if no filter
The NXP demo board
In addition, dedicated software is necessary to drive the FPGA & the ADC from the PC.
This software has been developed thanks to LabView, which means that at least the
LabView Runtime needs to be installed on the Laptop PC or the LabView environment
itself (v8.5).
These software tools are delivered by NXP either on a CD-ROM or through an internet-
based remote server.
!! Warning!! Please read carefully the following instructions before you start
plugging the demo board to the PC. It is especially necessary that you have the
CD-ROM ready to install the USB driver when you first plug the demo board to the
PC.

If you did not achieve this LED status, please start again from chapter 3, after you
unplugged/plugged the USB cable.
If you successfully reached this LED status, from now on it will remain the same,
whatever the data acquisition/analysis you perform.
4.2 Data acquisition/analysis:
Assuming that the demo board receives an input signal, you are now ready to acquire
data and analyze them to experience the ADC performance.
We kindly remind you that the first focus of this demo board is to demonstrate the
interoperability between the Lattice FPGA & the NXP ADC1x13D high speed converter. It
has not been optimized to demonstrate the full range of capabilities of the ADC. It is in
particular limited to the 1rst Nyquist band, so for input frequencies between 0Hz and half
the sampling frequency (F
S
).
On this demo board, the sampling frequency is by default defined by an on-board
oscillator, which generates F
S
= 60Mhz. So you can input a sine wave between 0Hz and
30MHz. Although the ADC1x13D080 datasheet mentions 65Mhz as the minimum
frequency, we have decided to use a 60Mhz oscillator since the Abracon ASE oscillator
has a very good jitter compared to other oscillators but it is unfortunately not easily
available for an output frequency higher than 60Mhz. It is then possible to demonstrate
good SNR performance (in the range of 72dB) over the [0;30]MHz band.

5. Using an external clock reference
5.1 Configuring the board:
On the back side of the PCB, a shunt resistor needs to be moved before you can supply
an external clock source to the board.
See the next picture:
Fig 13. Demo Board configuration for an external clock
Once the resistor is placed on the right foot print, you can plug your clock generator to
the demonstration board.
5.2 New demo set-up:
In addition to the already used sine wave generator, you now also need to use a low-jitter
generator (below 1ps RMS) to supply the clock to the demo board. According to the
ADC1x13D080 datasheet, the clock range is: 65Mhz up to 80Mhz.
In order to assess the SFDR performance, it is necessary to apply an input signal and a
clock signal which are synchronized and which have an appropriate ratio so that you get
an integer number of periods of the input signal over the 8192 samples captured inside
the FPGA SRAM.
So, you also need to synchronize the 2 generators so that they use the same time base.
Please refer to the generators user manuals.
So, we now end up with the following demo set-up:
