Techway ADC125 FPGA Mezzanine Card (FMC) offers four 16-bit A/D channels up to 125MSPS with full VITA 57.1 compliance. The ADC125 FMC is based on two LTC2185 dual Analog-to-Digital Converters (ADC) from Linear Technology. Through the I2C bus, users can fine-tune the gain, bias, and delay of the ADC. This ADC FMC FPGA Mezzanine Card allows users to sample signals with their own external sampling clock. Users also get the capability to use the on-board sampling clock. A trigger input is available to synchronize all channels with one-sample accuracy.
