VadaTech announced the FMC255. The FMC255 is a high-density ADC/DAC module with two LTC2107 that each provide a single channel ADC, 16-bit at 210 MSPS, dual AD9653 for total of six additional ADC, 16-bit at 125 MSPS, and a single LTC2000-16 that provides a single channel DAC, 16-bit at 1.25 GSPS. Additionally, the clock source can be via the front panel.
Note that the module does not follow the VITA57 height constraint. It has an additional daughter card that mates to the FMC module to allow it to accommodate the six ADC channels. For example, on the AMC FPGA FMC Carriers, it requires a full-height AMC panel to accommodate all the I/Os. The Carrier must have a monolithic panel (the FMC255 does not come with an FMC panel) to cover the FMC255 I/O envelope.
