The FMC165 provides two 14-bit analog-to-digital (A/D) channels supporting RF sampling at 2.6 GSPS and one 14-bit digital-to-analog (D/A) channel with sampling rates up to 5.2 GSPS (2.6 GSPS direct RF synthesis). The converters are clocked by either an internal clock source (optionally locked to an external reference) or an externally supplied sample clock. In addition, a trigger input for customized sampling control is available to users.
The FMC165 daughter card is mechanically and electrically compliant with the FMC standard (ANSI/VITA 57.1). It has front panel I/O and can be used on any FMC/ FMC+ compatible carrier in an air-cooled configuration. In a conduction-cooled environment, it can be used with Abaco FPGA carrier cards.
The design is based on Texas Instruments’ high-speed, high-performance ADC32RF44 A/D converter (ADC) and Analog Devices’ AD9129 D/A converter (DAC). The analog signals are AC coupled connecting to SSMB coax connectors on the front panel.
The FMC165 allows flexible control of clock source through serial communication buses. The card is equipped with power supply and temperature monitoring and offers several power-down modes to switch off unused functions in order to reduce system level power consumption.
The FMC165 is well suited for low power applications such as airborne where the highest level of performance is required while ensuring that mission range is not affected.
