Hey Terry,
The DAC38J82 is a JESD204B compliant DAC. It can have deterministic latency by use of subclass 1 operation. You would need to calibrate for this deterministic latency to synchronize it to the system.
The DAC3484 uses an SYNC input to synchronize…
Hi Chase,
Thank you for investigation.
1. I have change RBD to 32, but it is still same result.
2. " What is the reference clock into the TI JESD IP? " . I only have TX in TI JESD IP, the tx_sys_ref not used and tie 0 in example design.
3. Also…
Part Number: DAC38J82 Other Parts Discussed in Thread: LMK04828 , Tool/software: Hi Ti Experts,
We have been working on DAC38J82 device and struggling with the JESD interface for quite a few months. We designed our own board with Xilinx K7 FPGA and DAC38J82…
Part Number: DAC38J82 Other Parts Discussed in Thread: LMX2594 , Tool/software: Dear product line
my customer want to use DAC38J82 and LMX2594(PLL) in their design. they use an 80MHz external clock as input for DAC38J82 and LMX2594. then configure DAC38J82…
Part Number: DAC38J82 Hello,
I am reading the reference design(zc706_8b10b) about TI_204c_IP.
I have a question about sysref.
In TI_204c_IP_ref.sv, I see the Sysref signals tied to '0', like below.
So why do like this in reference design?
Thanks …
Hi Juraj,
See feedback below.
If the signal going to the DAC is midscale, then we would not expect a glitch as TXENABLE overrides the signal going to the DAC and makes it midscale. If there was a signal, then the abrupt shutting down of the signal will…
Hi Annie,
The DAC_RESET.DAC_RESET[0x0] register is used to issue a hardware reset pulse to the RESETB pin which is recommended before using serial interface for programming. Is this the missing registers which you are asking about?
Is the DAC38J82 still…
Hi,
We will try to add attenuator in the front end. we are suspecting whether this front end will provide a flat amplitude band over our operating bandwidth.
