IF/Baseband data signal generation

Product Summary

The XRM-DAC-D3/275 is an I/O Module which provides two 14-bit Digital-to-Analog convertors sampling at up to 125Msps.

It is aimed at IF/Baseband signal generation, provision is made for use of either an external or internally generated clock source. External trigger and auxiliary I/O ports are also provided.

Note: To ensure XRMs and XRM2s cannot be inadvertently installed on non-compatible FPGA platform boards the XRM2 connectors are mounted rotated 180° from those on XRM IO Modules. Most photographs of our mature XRM IO Modules are of the XRM version.
