Part Number: DAC38RF82 Hi team,
I'd like to design 2.3GHz-2.5GHz, typical 0.5dBm output system with two lanes input to the DAC.
Should DAC38RF82 support the above application?
If so, could you please let me know the recommended input configuration…
Part Number: DAC38RF82 Hi,
We are able to access the DAC registers.
The DAC is Configured following 81180 Mode.
Line Rate is 6.25 Gbps, DAC Sampling Clock generated 5 GSPS.
F=1 & K=32, so Sysref Generated : 19.53125 MHz. DAC Device clock for FPGA : 156…
Part Number: DAC38RF82 HI,
Our JESD configuration requires serdes to be operated at 6.25 for 5 GSPS sampling on 81180 mode.(DAC38RF82, 8 bit mode)
can we operate the DAC with following
F=1 and K=32 so that SYSREF required is 19.53125 MHz.
Regards,
Rajesh…
Part Number: DAC38RF82 Other Parts Discussed in Thread: LMX2592 , TEST , LMX2592EVM , Hello,
I am using DAC38RF82 interfaced with Kintex ultrascale FPGA.
I am finding a spur generated from DAC when sampling rate is 6.4 GSPS.
This spur starting from 1.5GHz…
Part Number: DAC38RF82 Hi Team, we would like to confirm the minimum pk-pk differential clock signal Voltage that the device needs to see?
Thank you in advance.

Part Number: DAC38RF82 Hellow, when I used SPI to program DAC38RF82, the odd registers of the address read and write normally, but the even registers of the address read and write goes error. If you known , thanks for your help.
Part Number: DAC38RF82 Hi Jim,
All the power and clocks are working properly,when I use the DAC38RF82.But now the value read back from 0x7f [15:10] is B11001, not B10000 as the datasheet said
Regards,
Wuge
Part Number: DAC38RF82 Other Parts Discussed in Thread: DAC38RF89 It say in the datasheet:
the DAC38RF82 or DAC38RF89 is capable of synthesizing wideband signals up to 2 GHz bandwidth with 16-bit input resolution and 2.66 GHz bandwidth with 12-bit input…
Part Number: DAC38RF82 The typical SPI clock rate is 100 ns for all registers except for temperature, and 1 us second for the temperature sensor per page 19 of the data sheet.
Any problems with using the slower 1 us period for ALL of the registers? There…
