FMCP-DAC12p0

FMCP-DAC12p0 is a 4 channels DAC module based on the industry standard FMC+ standard. It utilizes 2 AD9172 on the board for Digital to Analog Conversion and interfaces works through JESD204B IP core.

This is an advanced High-speed Digital to Analog Convertor in the market with 16-bit resolution capable of a sample rate at 12.6 GSPS and has dual channels in a single package. Each DAC IC can be configured via SPI interface separately.

The module includes an HMC7044 – High performance 3.2GHz JESD204B jitter attenuator for obtaining best results. On board the module there is a 100 MHz onboard VCXO; and 10 MHz  TCXO as reference clock, or external user reference clock;

To maximizing the utilization of FPGA carrier card transceivers FMCP-DAC12p0 has a carrier type FMC+ connector on the solder side. So an FMCP-ADC3p0 can be piggy backed by this module. This means that all 16 Rx and TX transceivers from the carrier card can be used. This is a major optimization of transceivers’ use offered by this module. on 1 FMC+ site a 4 channels DAC and a 4 channel ADC can coexist and provide major savings in space and resource use.
