FMC122 low pin count FMC ADC
2-channel 8-bit ADC - 2.5 Gsps
Description
The FMC122 is a Dual-Channel Multi-Mode ADC FMC daughter card, fully
Features
compliant with VITA 57.1 Standards. The card provides two 8-bit ADC channels
• Dual - Single 8-Bit Channel Operation
that enable simultaneous sampling of 2, or 1 channel with a maximum sample rate
- 2-Channel 1.25 Gsps A/D conversion Mode
of 1.25 Gsps (2-channel mode), or 2.5 Gsps (1-channel mode).
- 1-Channel 2.50 Gsps A/D conversion Mode
The sample clock can be supplied externally through a coax connection or supplied
• VITA 57.1-2010 compliant
by an internal clock source (optionally locked to an external reference). The clock
• Conduction Cooled
tree enables cascading of multiple boards for synchronous sampling. Additionally a
• 1.25Gsps or 625Msps DDR LVDS outputs
trigger input for customized sampling control is available.
• Coax front panel inputs on SSMC connectors
The FMC122 daughter card is mechanically and electrically compliant to the FMC
• Single ended AC-coupled analog inputs
standard as established by ANSI/VITA 57.1. The FMC122 has a LPC (low-pin count)
• Flexible clock tree enables:
160-pin connector, front panel I/O, and can be used in a conduction cooled envi-

ronment.
- external clock
The design is based on the E2V Quad ADC EV8AQ160 chip-set having DDR LVDS
- cascading multiple boards (optional)
outputs. The analog signal inputs are available on the front panel on coax connec­
• LPC - Ligh Pin Count Connector
tions and have individual calibration circuits for fine-tuning of gain, offset, and phase.
The FMC122 allows flexible control on clock source, sampling frequency, and
(160-pins)
• Mil-I-46058c Conformal Coating Compliant
calibration through an I2C communication bus. Furthermore the card is equipped
(optional)
with power supply and temperature monitoring and offers several power-down
modes to switch off unused functions.

The FMC122 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 FMC122 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 two 8-bit DDR LVDS busses at 1.25Gbps.
