The FMC645 is a Digital Signal Processor FMC daughter card based on the Texas Instruments TMS320C6455 device. The FMC645 daughter card is mechanically and electrically compliant to FMC standard (ANSI/VITA 57.1). The card has a high-pin count connector and can be used in a conduction cooled environment. The card is equipped with power supply and temperature monitoring and offers several power-down modes to switch off unused functions and peripheral interfaces. Several Gigabit differential pairs from the FMC connector are used to implement a PCIe and Serial Rapid IO interface between the FMC and the carrier. Many other digital I/O interfaces are also made available to the FMC carrier. Because of the use of level translators between the DSP and the FMC connector the FMC645 can fully operate on any VITA 57.1 compliant carrier. A 512MB DDR2 SDRAM on-board bank directly connects to the DSP thus providing the FMC645 with the memory resources required for demanding signal processing applications.
