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
2.5 Gb/s Digital RF Up Converter for AD9739A
