Hi,
I want to ask what are the logic levels of the CLKO_CLK1 pin, in output mode.
Can you tell what the High and Low levels are, and whether or not it needs to be buffered when connected…
Hey Juan,
I would check and see if there is any type of change in timing when you update the frequency on the FPGA. The device should just see samples coming in, regardless of the data that is embedded in the sample stream.
Unfortunately I do not have…
Part Number: DAC5688 Other Parts Discussed in Thread: LMK04828 Hi Team,
(1) Does CLK2/CLK2C accept LVDS? Or is LVPECL only available?
(2) For LVPECL, I want to confirm how to set the clock interface. Per datasheet, it looks :
- VCM = CLKVDD 1.8V * 2…
Part Number: DAC5688 Other Parts Discussed in Thread: SN74AXC4T774 There's no information in the datasheet for default values for the CMOS IO threshold values. I'm looking to interface this DAC with a 1.8V IO FPGA bank
Part Number: DAC5688 Hi all,
I am looking for the ESD characteristics of the DAC5688 but this data does not appear to be on the datasheet. Would it be possible to provide this data and then have the datasheet for this part be updated to include the ESD…
Part Number: DAC5688 Hi,
I would like to know what is the Full complex mixer maximum frequency. On page 31 it shows the next equation
We are using the next Clocks configuration:
- CLK1 = 250 MHz single ended LVCMOS33
- CLK2 = 500 MHz diff LVDS
What is…

Hi Team,
Good day! Kindly help to provide the complete thermal information for this part DAC5688IRGCR. C an it be top cooled and if yes what is the value of theta JC top resistance?
The customer…
Hello Juan,
I have taken some measurements using the DAC5688 EVM with the clocking setup you have described above.
Clk1 - Single Ended, 250MHz
Clk2 - Differential, 500MHz
I generated a 1MHz sine wave and sent it to the DAC using HSDC Pro and I am not…
Part Number: DAC5688 Hello,
My customer uses DAC5688 on their own board. They sometimes get good waveform as shown lower left, but they sometimes don't do as shown lower right. Would you please tell me what do you suppose the root cause would be?
