High speed dac with ram
WebDec 1, 2024 · In this article, we’ll develop firmware that will serve as the basis for high-precision, high-speed signal generation. I recently designed an arbitrary waveform generator (AWG) PCB that is built around a C8051F360 microcontroller and a TxDAC from Analog Devices. These two ICs communicate via a parallel interface that allows me to generate ... WebTo accurately play digital audio at high speed a dac that can support a very high sample rate is required. ... If so you would probably want to add external ram on the programmable logic side as the zynq arm cores top out at 1GB. Going to need a fairly skookum head driver amplifier to get decent treble at 80* speed! 2.
