Part Number: DAC38J82 Other Parts Discussed in Thread: LMK04828 , , Good day to all!
We are using the DAC38J82 along with LMK04828 and FPGA Polarfire. An FPGA is transmitting data to the DAC38J82 and the LMK04828 is providing clocks and SYSREF. Our lane…
Part Number: DAC38J82 Other Parts Discussed in Thread: DAC38J84EVM , LMK04828 Hi there,
We have a working system with Xilinx Ultrascale FPGA JESD204 TX to DAC38J82. The FPGA JESD is configured at 8 Lanes with lane speed at 10Gbps. Reference clock to both…
Part Number: DAC38J82 Hello TI Tea,
I am using DAC38J82 in my new module.
I saw the pictorial representation to place ac coupling capacitor of JESD204B line near to transmitter device in TEXAS INSTRUMENTS JESD204B Physical Layer training material.
But…
Part Number: DAC38J82 Hi
From the data sheet both the inputs to and the outputs from the FIR filters seams to be 16-bits. But I am unable to find, from the data sheet, any detailed description of the resolution and where and which bits are dropped, rounded…
Part Number: DAC38J82 Other Parts Discussed in Thread: DAC38J84 Hi,
I am using DAC38J82 DAC IC.
For JESD interface,it is mentioned in your training material "TEXAS INSTRUMENTS JESD204B series The Physical Layer PHY" that the ac coupling capacitors has…
Part Number: DAC38J82 Other Parts Discussed in Thread: DAC38RF82 Is the interpolation done in steps of interpolate by two, where one zero is inserted between all samples and one FIR filter is applied, or are all zeros inserted between the samples at once…
Part Number: DAC38J82 Hello All,
I'm working with DAC38J82 in a customised hardware. I'm having an issue in getting the DAC output. Here is my configuration.
DAC input clock is 2457.6MHz. DAC PLL is not used. No SYSREF input.
I'm trying to use…
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 waveform…
Part Number: DAC38J82 Other Parts Discussed in Thread: DAC38J84 , DAC38RF82
Hi all, I'm trying to bring up the DAC38J82 to operate with complex samples. I need few clarification regarding the internal path flow. I understand that the DAC38J82 has two…
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 v1.…
