Analog to digital converters FMC @ 125 MSPS

ADC125 is a fully compliant FMC mezzanine (VITA 57.1) which offer 4 16 bits A/D channels up to 125 MSPS.

ADC125 FMC is based on 2 dual Analog-to-Digital converters from Linear Technology : the LTC2185.

This mezzanine allows you to sample your signals with your own external sampling clock. You also get the capability to use the on-board sampling clock. A trigger input is available to be able to synchronize all channels with a 1 sample accuracy.

You are able to fine-tune the ADCs through the I²C bus. ADC gain, bias and delay can be set-up according to your needs. Temperature and power monitoring can be check directly from the FPGA.
