from the DAC datasheet:
The AD5370 has a high speed serial interface that is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards and can handle clock speeds of up to 50 MHz.
The serial word (see Table 10) is 24 bits long; 16 of these bits are data bits, six bits are address bits, and two bits are mode bits that determine what is done with the data
24 bits per channel * 32 channels = 768 bits each update 50Mhz / 768 = 65k theoretically we should be able to get a sampling frequency of 65 kHz
DVCC = 2.5 V to 5.5 V VDD = 9 V to 16.5 V VSS = −16.5 V to −8 V VREF = 3 V AGND = DGND = SIGGND = 0 V

EXT REF on the DAC is SMB connector
maybe get BNC to SMB cable and BNC connector on our board? https://www.centricrf.com/cable-assemblies/sma-cable-assemblies/18ghz-flexible-rg405-086-sma-smp/c572-086-09b-cable-smp-f-to-sma-m-086-flexible-18ghz-vswr-1-25-9/?gclid=CjwKCAjwwsmLBhACEiwANq-tXI_RbwLa_R6KtDWBK9m9Df5ki88685Jkxt1tVMaLrHdn49xHgrhX7BoC2bcQAvD_BwE
