DATASHEETFMC176, FMC VITA 57.1 Compliant
Quad 250Msps A/D - Dual 5.6Gsps D/A @ 14-bit
The FMC176 is a quad channel ADC anddual channel DAC FMC. This daughtercard provides four 14-bit A/D channels at
250Msps and two 14-bit D/A channels at
5.6Gsps (2.8Gsps direct RF synthesis) clockedby either an internal clock source (optionallylocked to an external reference) or an
externally supplied sample clock. In addition, atrigger input for customized sampling control
is available to users. The FMC176 daughtercard is mechanically and electrically compliant
to the FMC standard (ANSI/VITA 57.1).
ANSI/VITA 47

The FMC176 has a high-pin count connector,
front panel I/O, and can be used in a
conduction cooled environment. The designis based on Analog devices’ AD9250 dual
channel 14-bit 250Msps Analog-to-Digitalconverter and Analog devices AD9129
single channel 14-bit 5.6Gsps Digital-toAnalog converter. The analog signals are AC
coupled connecting to MMCX or SSMC coax
connectors on the front panel.

DATASHEETFMC176, FMC VITA 57.1 Compliant Quad 250Msps A/D - Dual 5.6Gsps D/A @ 14-bit
The FMC176 allows flexible control
on clock source, analog input gain andover 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.
