TSW30SH84 EVM+ TSW1400 2. Using example source

“C:\Program Files (x86)\Texas Instruments\TSW308x\Configuration Files \ TSW30SH84_32bitLVDS_4Channel\REVB\LMK04808 Clock Distribution Mode”

-Example file

“DAC34SH84_1474p56MHz_2xINT_NCOenabled_30MHz_single_sync_source_mode” and “DAC34SH84_1474p56MHz_2xINT_NCOenabled_30MHz_dual_sync_source_mode” were used

1. What’s a problem?

2. what’s different between single mode and clock distribution mode?
