1. Overview
The FMC 228 card implements a wideband, quad-channel, 16 - bit, 1.2 GSPS (600Msps Direct RF Synthesis) DAC function, clocked by an internal clock source (optionally locked to an external reference), or an externally provided sampling clock. A trigger input is also provided for the user to customize the sampling control. The FMC 228 conforms to the FMC standard (ANSI/VITA 57.1) mechanically and electrically. The card has a multi-pin connector, front panel I/O, and can be used in a conduction-cooled environment. The analog signals are AC coupled to the SSMB coaxial connector on the front panel. The FMC 228 allows flexible control of the clock source via a serial communication bus.
