High speed converters interoperable with FPGAs

NXP Semiconductors’ CGV series of JESD204A-compliant data converters are interoperable with Altera’s Stratix IV GX and Arria II GX FPGA families. The converters are suitable for cellular base stations and other wireless communication infrastructure equipment, as well as medical, instrumentation and military/aerospace applications. NXP offers ADC and DAC evaluation boards that include the Altera HSMC interface for easy connection to Altera FPGA evaluation boards allowing rapid demonstration of device interoperability. CGV (Convertisseur Grande Vitesse) designates NXP's compliant, superset implementation of the JEDEC JESD204A interface standard, with an enhanced data transfer rate of 4.0Gbit/s, better reach of 100cm, enhanced features such as multiple DAC synchronisation and assured FPGA interoperability. The enhanced CGV features include MDS (Multi Device Synchronization) for the DAC1408D series of D/A Converters, which is not specified, but informatively discussed in the JEDEC specification. NXP has implemented this optional feature to enable LTE MIMO base station and other advanced multi-channel applications. The implementation of MDS enables up to sixteen DACs data streams to be sample synchronised and phase coherent.
