Part Number: DAC38J82 Hi team,
Here is a question from one of our customers:
When using DAC38J82EVM , I use DDS on FPGA to generate a sine wave and output it. The waveform measured by oscilloscope is as follows:
Theoretically, it should be a smooth…
Part Number: DAC38J82 Dear sirs,
Could anybody tell me how can I control the output gain of the DAC ( DAC GAIN ) . I have used the Mixer_gain: 6dB and the Qmc_gainA and Qmc_gainB with another 6dB , but I cant find the DAC GAIN as shown on the Functional…
Evgenly,
The IBIS model can be found under the "Design and Development" Tab inside the DAC38J82 product folder on the TI website. I am currently trying to find out if an AMI file was ever created.
Regards,
Jim
Part Number: DAC38J82 Other Parts Discussed in Thread: LMK04828 Hi team，
When one of our customers used DAC38J82 for development, Serdes PLL could not be locked after configuring parameters, and FIFO reported an error;
The customers use DAC3XJ8X GUI…
Part Number: DAC38J82 Hello,I have some questions about configurations and line rate. I use DAC38J82 and output rate is 1GSPS per converter(DACA and DACB). In this way, LMF is 821,S is 2,HD is 1,interpolation is 1,the serdes line rate
is 5Gbps,DACCLK…
Part Number: DAC38J82 DEARS.
I am reviewing DAC38J82 design.
My setup is as follows.
MSPS Range : 100MSPS to 600MSPS INPUT IF : 368.64Mhz INPUT TYPE : REAL Band Width : 100Mhz Sampling Clock : 245.76Mhz Decimation : 4 DAC NCO : 368.64Mhz LMFS :…
Part Number: DAC38J82 Are there any examples of configuration registers?
I use ALTERA FPGA
LMFS :4211 DAC_CLK:400m
I use the register value generated by GUI and configure DAC through SPI, but I can not output the desired waveform all the time. …
Part Number: DAC38J82 Other Parts Discussed in Thread: , LMK04828 The dac38J82 output contains other unwanted waveforms.
For example, when you want to output 70M, but also output unwanted 30M, 50M, 90M, 110M, 130M and so on, I found that they are added…
