Part Number: DAC37J84 Hi, Support
Currently we have a FPGA circuit board interfacing with DAC37j84 boards via FMC connector. However the power for FPGA board and power for DAC circuit board side are separated.
My question is that : " Is it safe the…

Have couple question regarding the DAC37j84 datasheet, can you please help with it??
1. The DACCLKP/N and SYSREFP/N internal termination. from the datasheet, it shows…
Part Number: DAC37J84 Other Parts Discussed in Thread: DAC38J84 Hi team,
My customer has a question regarding the DAC37J84 that they are using in one of their critical designs.
It seems that DAC chip puts out about 200mV of DC even when disabled. They measured…
Part Number: DAC37J84 Hi,
From dac37j84.pdf page 8, 6.5 DC Electrical Characteristics table I can see that the DAC gain error is 2% FSR and the gain mismatch error is 2% FSR.
Question1:
What is gain mismatch error? Is this gain mismatch between two separate…
Part Number: DAC37J84 Hello,
My customer has a few questions about the SERDES Equalizer of the DAC37J84.
1. What is the minimum time for the equalizer to adapt?
3&5. What does UI mean? How much is 48UI converted to seconds?
Please let us know if…
Part Number: DAC37J84 Hi Team, Posting for our customer working on a DAC37J84 custom board, currently experiencing an issue where its SerDes PLLs doest want to lock. I understood it by reading 0x6C register - it's value is 0x000F (yes, I've tried to reset…

When DAC37J84 is used to change the sampling rate,JESD204B protocol can be established at sampling rates 1200MSPS 1000MSPS 600MSPS 500MSPS, but cannot be established at sampling rates below 500MSPS(400MSPS 300MSPS…
Part Number: DAC37J84 Hi sir,
I would like to use a quad high speed DAC to drive two IQ modulators.
I need to send 130Ms/s to each DAC input. I need DAC oversample x2 the inputs, so each DAC frequency sampling would be 260Ms/s.
Both IQ pair must be perfectly…
