AD9102 acts as a waveform generator, exiting one SRAM, and this SRAM has some information about period, however, I can't find some information about amplitude. what's matter about it.
Another question is that for "4096x14-mode memory" ,what is the mean for 4096?
The SRAM contains samples of a waveform you wish to send to the 14 bit DAC core. The AD9102 waveform generator reads samples from the SRAM at the DAC sampling rate using an address counter. You can store up to 4096 14 bit samples in the SRAM.
