2.5 Gb/s Digital RF Up Converter for AD9739A

Overview

The MVD Upconverter core is a drop-in module that converts multiple baseband I-Q signals to analog RF signal with AD9739 or AD9739A 14-bit RF DAC sampled at up to 2.5 GHz.

It includes the following functions:
An Interpolation x16 + RF Modulation per each independent RF channel
An Output Processing module which combines up to 32 independent RF interpolator channels
A clock management module
An OSERDES module which connects the LVDS IO to the RF DAC
A CPU BUS to configure the parameters of the Upconverter

Key Features

Drop-in module for Spartan-6, Virtex-6, Artix-7, Kintex-7, Virtex-7, Zynq FPGAs
Provides direct RF synthesis for baseband I-Q signals (DC to 1.25 GHz)
Support for 2nd and 3rd Nyquist zone for carriers frequencies up to 3GHz+
Includes clock management module
Very low FPGA resources required
32 or 64 MHz minimum bandwidth per RF channel
In-band ripple < 0.2 dB and SNR > 75dB
Carrier frequency dynamically adjustable with sub-Hertz precision
Dual 14-bit LVDS output busses directly tied to AD9739/A input data pins (compatible with 11-bit for AD9737A)
Can be modified for using others RF DAC (please contact MVD)
Fully synthetizable RTL VHDL design (not delivered) for easy customization
