Description

The DUAL_ADC&DAC is a dual channel A/D and dual channel D/A FMC daughter card. The card provides two 14-bit A/D channels and two 12-bit D/A channels. The ADC and DAC can be clocked by an internal clock source(OCXO) or an externally supplied sample/reference clock. There is also an external trigger input for customized sampling control.

The DUAL_ADC&DAC daughter card is mechanically and electrically compliant with FMC standard (ANSI/VITA 57.1). The board has a high-pin count connector and the front panel I/O, and it can be used in a conduction-cooled environment. The design is based on TI’s ADS62P49 dual channel 14-bit 250Msps ADC and TI’s DAC3162 dual channel 12-bit 500Msps DAC. The analogue signals are AC coupled, connecting to MMCX coax connectors on the front panel.
