4-Channel DAQ Module – High-Pin-Count
The FMC176 is a quad channel ADC and dual channel DAC FMC. This daughter card provides four 14-bit A/D channels at 250Msps and two 14-bit D/A channels at 5.6Gsps (2.8Gsps direct RF synthesis) 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 FMC176 daughter card is mechanically and electrically compliant to the FMC standard (ANSI/VITA 57.1).
The FMC176 has a high-pin count connector, front panel I/O, and can be used in a conduction cooled environment. The design is based on Analog Devices’ AD9250 dual channel 14-bit 250Msps Analog-to-Digital converter and Analog Devices’ AD9129 single channel 14-bit 5.6Gsps Digital-to-Analog converter. The analog signals are AC coupled connecting to MMCX or SSMC coax connectors on the front panel.
The FMC176 allows flexible control on clock source, analog input gain and over range detection through serial communication busses. Furthermore 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. It is well suited for low power applications such as airborne where the highest level of performance is required while ensuring that mission range does not get affected.
