Part Number: DAC38J84 Hi,
I am using DAC38J84 component in my design.
I have checked two different cards with a thermal camera and compared the case temp. to the internal temp. sensor.
The case temperature of the DAC was the same (in both cards) but there…
Part Number: LMK04828 Hello,
I am currently working with the LMK in conjunction with the FMC144 card from Abaco. While the DACs theoretically can reach up to 2.5 GHz, they are currently stuck at their default frequency of 368.64 MHz. I'm utilizing a C…
Hi Juan,
If you have K set as 2, it may not allow adequate RBD for the link to come up correctly. Is it possible for you to set K as 16 and modify sysref accordingly?
Thanks, Chase
Part Number: DAC38J84 After reading other posts/questions about the DAC38J84 and reading through the datasheet, I still have a question about the correct values to set the registers in the DAC38J84 for JESD204B operation using:
8 JESD204B lanes total…
Part Number: DAC38J84 In 7.3.27 of SLASE17B an equation is given to calculate IOUTFS. It is dependent on VEXTIO which is the same as VREF if the internal reference is used. Is there any way to determine a tolerance for IOUTFS given that only a typical…
Hi Amy,
If the user is using the DAC38J84 along with a RF modulator (i.e. TRF3705), then the NCO can be programmed as a "negative frequency" with I/Q phase in -180 degree fashion. The user can then see the output of the RF modulator with the signal on…
Hi Amy,
After re-reading this again, the SFDR value of 74.23 dB was measured on our EVM. The device was not characterized under the exact conditions you are using. However, looking at page 13 in the datasheet you can extrapolate that a SFDR of 74.23 dB would…
Part Number: DAC38J84 Hi Team,
As the tittle, I wonder what's the maximum rate of DAC38J84's SPI interface?
Period of SCLK is 100ns typically in datasheet, can it up to 50ns(20MHz)?

Part Number: DAC38J84 I'd like to verify that the JESD204B parameters have been received correctly during the ILAS sequence. The datasheet is unclear on which registers are RO and which are RW, so I'm not sure if they represent the received data, or the…

Hi everyone,
I am trying to use DAC38J84 at it's highest sampling rate. There are 8 JESD lanes on my board which works at 10Gbit/s. I use LMK04828 as a clock source.
I can use the DAC…
