Part Number: DAC38J84 Hello,
Looking at the 0x6C register, I see that there is the "alarm_sysref_sh". The GUI states that :
But in the datasheet, it is marked as reserved :
Is this a 'functioning' alarm? If so, what are CDRV_SER, OSTROBE,…
Part Number: DAC38J84 Other Parts Discussed in Thread: LMK04828 hello, jim
My custom board can work normal when setting as follows
Fdata = 300M
interpolation = 4
Fdac = 1200M
SerDes Linerate = 6000M
but when I double the interpolation to 8…

I am working with DAC38J84 in NCO mode in the following way:
1. set a new frequency through SPI (registers 0x14 - 0x16)
2. using a one sysref pulse to update the NCO ( 0x1E = 2222 , 0x1F = 2220)
DAC_CLOCK = 1920MHz
SYSREF WIDTH = 5…

Part Number: DAC38J84EVM Other Parts Discussed in Thread: DAC38J84 Dear,
I bought the dac38J84_evm board to bench my project.
But the SFDR is very bad -48dBc (hd2)
JESD204B - 6.144Gbps
Sample rate 614.4 MSPS (FPGA)
Interpolation : 2
Part Number: DAC38J84 I configured the VC707 and DAC38J84, and the indicator light showed that they were properly configured. I followed the Quick Start Page of DAC38J84EVM without tuning the other control buttons in DAC38J84EVM.
I connected the SMA output…
