Other Parts Discussed in Thread: DAC38RF89 art Number: DAC38RF89
I want to use EyeScan for test.
I connected the JTAG according to the EyeScan documentation, configuring the DAC38RF89 and FPGA, and after the DAC output port has a waveform output. I conducted…
Part Number: DAC38RF89 We config the DAC38RF89 as follow.
At the begin,the two DACs work OK. During test, the DAC0 works wrong. It has no output,but the DAC1's output is OK.
We check the registers value of DAC38RF89, there are no changes.
When we set…
Part Number: DAC38RF89 Hi, Team
Siglent is using the DAC38RF89 in AWG application.
From datasheet 8.3.20 Gain Block section, it describes the GAINAB/CD Register(8.5.39), but didn't give a list/table what's the exact value of gain value/range in the register…
Part Number: DAC38RF89 In our application, the flowing is DAC38RF89's configuration. When we output 1GHz signal, there is no spurs. But other frequencies, it can see spurs.
We found that it was caused by the inverse sinc filter. If disable the inverse…
Part Number: DAC38RF89 I want to do prbs31 test on JESD204B interface. FPGA is transmitter, DAC38RF89 is receiver.
But the Xilinx JESD204 IPcore cannot sent prbs31 test pattern, how can I do the test?
If use Xilinx IBERT debug tool to send prbs pattern…
Part Number: DAC38RF89DAC38RF89 have two DACs,we want to change the DAC1's Fullscale Output Current. But there is only one register(page4,0x0D) to set the current. When change the value, the DAC2 is changed too.
How can change the two DAC‘s Fullscale…
Part Number: DAC38RF89 Hi, Team
My customer wants to do a PRBS31 test, by using the checker in DAC38RF89 to check if the physical layer is good.
They can make the DAC38RF89 work well if FPGA output tone.
But they don't know how to allocate the PRBS31…
Part Number: DAC38RF89 Hi,
I would like to confirm the minimum required differential input voltage for the DAC38RF89 SYSREF and DACCLK inputs. The datasheet says typical 800mV and max 2000mV. I understand max is top value above which input differential…
Part Number: DAC38RF89 I config DAC38RF89 as fallowing.
I-channel is path AB of DAC A,Q-channel is path AB of DAC B. The phase of NCO of DAC A is set to 0 degrees, and the phase of NCO of DAC B is set to 90 degrees.
When we measure the two NCO's signal…
Part Number: DAC38RF89 Hello,
My customer have 2 questions about DAC38RF89.
[Q1]
Please tell me the delay time from "TXENABLE = Low to High" to enable the output.
[Q2]
Please tell me the delay time from "TXENABLE = High to Low" to force the…
