ZC706 with AD9136-FMC-EBZ Code Group Sync going in and out

Hi rdb9879

it looks there is a device tree available for the 9136 here: 

https://github.com/analogdevicesinc/linux/blob/master/arch/arm/boot/dts/zynq-zc706-adv7511-ad9136-fmc-ebz.dts

How did you build the hdl. what parameters did you used, what operation mode did you select for the JESD ? 

Thank you, 

Laszlo

I did see the device tree, but it's currently "not supported" and I couldn't figure out how to get it to build (I was given some instructions to try here: https://ez.analog.com/linux-software-drivers/f/q-a/167077/zc706-and-ad9136-how-to-include-reference-design-dtsi-file, but I couldn't figure it out). Thus, I went with bare metal CPU. For HDL, I built the analog devices "dac_fmc_ebz" reference design for the zc706 target. I configured the "config.tcl" to use JESD mode 11 set for device AD9136, single link mode, which should give these parameters:

M = 2

L = 8

S = 2

F = 1

HD = 1

N = 16

Np = 16

Thanks. You were exactly right.

Hello, I also find a similar problem. The sync signal kept going in and out. I checked the clock, channel, etc., and found no errors. I let FPGA send K28.5 all the time, and found that sync is also going in and out in the same way. May I ask what may be the cause of this problem? Thank you

Please can you open a thread with the setup you have ? 

Thanks, 

Laszlo

This is the phenomenon when sending normal data and K28.5

Hello, this is a PCB designed by myself. The parameters are:

DAC CLK: 500MHz

DAC sysref: 3.90625MHz

FPGA sysref: 3.90625MHz

FPGA gtxclk: 250MHz

And I use HMC7044 to generate the clock

When FPGA keeps sending K28.5, it will also find sync going in and out, I tried to change lanerate(10G, 3G), but it also didn't work. Thank you!

Hello, this is a PCB designed by myself. The parameters are:

DAC CLK: 500MHz

DAC sysref: 3.90625MHz

FPGA sysref: 3.90625MHz

FPGA gtxclk: 250MHz

And I use HMC7044 to generate the clock
