This Mezzanine Card allows you to connect 2 ZMOD adapters. For example for connecting the Zmod ADC 1410 and Zmod DAC 1411 SYZYGY modules on the Digilent Genesys ZU.
Many FPGA boards have a FMC port. The Genesys ZU board has only one SYZYGY ZMOD connector, but also has a FMC port. Many applications, such as software defined radio (SDR), profit from both a high speed ADC and DAC. This FMC adapter allows you to connect 2 ZMOD modules.
I'am not an electrical engineer - and as such cannot guarantee that you won't fry your board(s). It was tested to work with the Genesys ZU and the code in the marcvhoof/genesys-zu-notes repository. Some parts of the SYZYGY specification are not implemented (yet). Such as the I2C functionality, module detection and power configuration. Feel free to modify and improve.
For testing purposes more were assembled and as such, I have a few left. So if you want an assembled board, without the connectors, feel free to reach out to me. I'd be happy to send you a board for shipping costs. If you want to assemble a board yourself, follow the guide.
- a board with a FMC port
- a software implementation (see marcvhoof/genesys-zu-notes repository )
I used [JLPCB]{jlpcb.com). Take JLC7628 for impedance control. I paid 44$ including shipping and assembly for 5 boards. You need to order a stencil if you don't want to create this yourself.
The connectors are not in the standard inventory. You can find them in different places. FMC Samtec - ASP-134604-01 - 1 per board ZMOD Samtec - QSE-020-01-L-D-A - 2 per board
