FMC125 high pin count FMC ADC
4-channel 8-bit ADC - 5 Gsps
The FMC125 is a Quad-Channel Multi-Mode ADC FMC daughter card, fully
compliant with VITA 57.1 Standards. The card provides four 8-bit ADC channels
Features
that enable simultaneous sampling of 4, 2, or 1 channel with a maximum sample

(1-channel mode).
- 2-Channel 2.50 Gsps A/D conversion Mode
The sample clock can be supplied externally through a coax connection or supplied

The FMC125 comes with an integrated Cross Point Switch allowing flexible mapping of analog inputs to the converters. Unused converters
can be placed in standby mode or a full standby mode can place all channels in power saving mode.
With the build in DMUX feature of the FMC125 it is possible to adapt the digital output interface to the carrier hardware. When the DMUX
feature is enabled each channel has a 16-bit Double Data Rate LVDS bus at 625Mbps (full speed sampling). Without de-multiplexing the
digital output interface compromises four 8-bit DDR LVDS busses at 1.25Gbps.
