3.1 Requirements and handling instructions


The FMC204 daughter card must be installed on a carrier card compliant to the FMC
standard.

The FMC carrier card must support the high-pin count connector (HPC 400-pins).

The carrier card must support VADJ/VIO_B voltage of +2.5V (LVDS support) for
FMC204 revision 1. The carrier card can support VADJ/VIO_B voltage range of 1.65V
to 3.3V for FMC204 revision 2, but typically VADJ will be 1.8V or 2.5V for LVDS
operation.

Do not flex the card.

Prevent electrostatic discharges by observing ESD precautions when handling the
card.

3.2 LVDS requirements

Each D/A device has an independent DDR LVDS data bus. When a D/A device is operated
in single-channel mode, the full rate of 1Gsps is supported. The digital transfer rate can be
lowered by enabling the interpolation (x2 or x4) in the D/A devices. When the D/A devices
are operated in dual-channel mode, the maximum data rate without interpolation is 500
Msps. 1Gsps can be achieved using the times 2 interpolation in the D/A devices.
