See attached for vendor stackup used on this board. For your other question, the 19 mil traces are loosely coupled at 50 Ohms single-ended and the 9 mil traces are 100 Ohm differential coupled traces.
Part Number: DAC39J82 Other Parts Discussed in Thread: DAC5687 , I have used the DAC5687 and was able to phase align multiple chips via the PHSTR input.
How do I phase align the outputs of multiple DAC39J82, to ensure they always come up with same phase…
Part Number: DAC39J82 Other Parts Discussed in Thread: AFE7444 Hi,
There are three DACs used in our design. All three operate at different sampling and update rate.
Will there be any impact on performance if the power rails are shared? Example: Powering…
Part Number: DAC39J82 I sort of understand the answer to time syncing several DAC39J82 together, which I will incorporate. I'm using the NCO and need to ensure each NCO in multiple chips come up at the same phase relative to each other. The syncing ensures…
Part Number: DAC39J82 Other Parts Discussed in Thread: LMK04832
We have used LMK04832NKDT for generation of JESD204B clocks and sampling clocks for DACs and Xilinx MPSoC PL MGT. Schematic design has been attached, please provide your feedback.
Part Number: DAC39J82 Other Parts Discussed in Thread: DAC39J84 , , DAC37J82 , DAC37J84 Hi,
We are planning to use DAC39J82 in our application where the following are our requirements (in both cases DAC LO is not used)
For Output 1: FDAC is around 2800…
Part Number: DAC39J82 Other Parts Discussed in Thread: TSW14J10EVM , LMK04828 Hi,
We have ordered the Eval board DAC39J82EVM and have started the characterization.
We are trying to measure NSD in our LAB , but we are unable to meet the numbers due to equipment…
Part Number: DAC39J82 hello
we have two of dac39j82, both using LMF 421, 4 lanes mode.
Due to pcb layout reason, for the first dac, we want to use pin Rx0, Rx1, Rx2, Rx3 for the 4 jesd lanes. for the second dac, we want to use pin Rx4, rx5, rx6, rx7 for…
Part Number: DAC39J82 Hello
We want to use a LVDS chip (IDT 8P34S1102NLGI) to connect to the SYSREF pins of the DAC39J82. According to the IDT datasheet, it lists its DIFFERENTIAL OUTPUT VOLTAGE as 247mV - 454mV.
Can the DAC see this differential voltage…
