Hi John,
This is unexpected. Given CDR is locked we should observe HEO/VEO - otherwise device will not be locked.
1). Please confirm customer is indeed using correct methodology for reading/writting into the registers. Please note below FAQ for details…

We would like to ask your help regarding the customer's inquiry below.
I'm planning on developing a HD-SDI 2:1 switch using 2 x LMH0324…
Hi Kawai-San,
I have used USB2ANY box with the LMH1218EVM. On USB2ANY software I turn on 3.3V supply. Then - this turns on 3.3V on USB2ANY connector. Under this condition - I was able to run LMH1218EVM GUI and I did not have to make any change on the…
Hi Alan,
You can use LMH1218EVM for this test. These two devices have the same performance.
I was thinking about this and why there is a difference between Phabrix and Tek WFM you noted earlier. In some implementation of the FPGA at SD rate, SD rate is…
Part Number: LMH1219 Other Parts Discussed in Thread: LMH1218EVM , USB2ANY , , Hello,
Is USB2ANY the only way to program/configure the LMH1219EVM and LMH1218EVM? Can the USB ports be used for the same thing?
Thanks,

Hi Eric,
Something doesn't look right. You are getting 1.15UI of alignment jitter. I suggest if you can please get one of our LMH1218EVM for correlation and check/correlate with your own result. I expect far less jitter.
Another thing you can try…
HI Dan,
LMH1218 performs input EQ automatically until you initiate initialization settings that forces manual EQ instead. Having said this, i expect performance to be the same after POR versus if you simply do a CDR reset. It seems your test result is…
Hi Nasser,
thanks! I have just tried to order LMH1219EVM, LMH1218EVM and LMH1297EVM, but only LMH1218EVM looks like to be orderable. The other two is directing to a link to get approvel for SW download.
Could you please check and advise how to provide…
Hi Philip,
This board is a reference design and is not available for purchase.
You can purchase LMH1219EVM + LMH1218EVM + 12G SFP and these would provide the same function.
