Featuring simultaneous sine and ACMOS/TTL outputs at up to 68 MHz, the DDS7m direct digital synthesis module’s parallel interface allows frequency and phase updates in less than 400 ns. Used with the master clock output and external clock input, up to 10 modules can be phase-synchronized in a multiple-phase system. The unit’s RS-232 control mode features non-volatile storage of all settings. Its internal clock is accurate to 10 ppm.
