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?
