FMC122 – Dual-Channel Multi-Mode 8-bit ADC 1.25 GSPS / 2.5 GSPS | LPC ADC Board

Multi-Channel Multi-Mode 8-bit ADC 1.25 Gsps / 2.5 Gsps
FMC-LPC Analog-to-Digital Converter Board
FMC VITA 57.1 Compliant

The FMC122 is a Dual-Channel Multi-Mode A/D FMC, fully compliant with VITA 57.1 Standards. The card provides two 8-bit ADC channels that enable simultaneous sampling of 2 or 1 channel with a maximum sample rate of 1.25 GSPS (2-channel mode) or 2.5 GSPS (1-channel mode).

 

The sample clock can be supplied externally through a coax connection or supplied by an internal clock source (optionally locked to an external reference). Additionally a trigger input for customized sampling control is available.

 

The FMC122 daughter card is mechanically and electrically compliant to the FMC standard as established by ANSI/VITA 57.1.

 

The design is based on the E2V Quad A/D EV8AQ160 chip-set having DDR LVDS outputs. The analog signal inputs are available on the front panel on coax connections and have individual calibration circuits for fine-tuning of gain, offset, and phase.

 

The FMC122 allows flexible control on clock source, sampling frequency, and calibration through the I2C serial communication bus.
