Description

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