LMK04821EVM: take use of SYSREF to generate a 50kHz signal

Part Number: LMK04821EVM
Other Parts Discussed in Thread: LMK04821, LMK04832

Hi there,

I'm using LMK04821EVM to generate 50kHz 100kHz 300kHz and 500kHz signal. The frequency is low so I take use of SYSREF with SDCLKout1 and SDCLKout2. The problem I found is it didn't output any voltage swing when I set these two channels as SYSREF. After I set is as Divider Only(Device Clock), the output clock is fine.  Did I miss anything in the SYNC/SYSREF page to enable the SYSREF output continuously?  Here, I also attach the .tcs file for this design.

Thanks.
