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…
Part Number: DAC38J84 Other Parts Discussed in Thread: LMK04828 ,
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…
Part Number: DAC38J84 Other Parts Discussed in Thread: LMK04828 Hi
I am using LMK04828 PLL from which clock is given to 2 DACs. Clock is provided to all 2 DACs simultaneously and the clocks are synchronised.
NCO reset is also done simultaneously.

Part Number: DAC38J84 Hi Teams,
I'm evaluating DAC38J84 according to SLAA696 DAC38J84 device initialization and sysref configuration . However, I came across several problems. Can you help me to solve these issues?
1, SYNCB will be pulled low, after…
Part Number: DAC38J84 Hi,
It is mentioned in datasheet of DAC38J84 IC that the output impedance of analog output as 300k ohms.
To calculate trace width should I match to 50 ohms or 100 ohms.
