947 can operate in Dual-pixel clock mode only if both ports operate off the exact same pixel clock frequency and phase. Given that is the case, you can connect any one of the oLDI clocks to 947 ..,since both clock rates need to be same

Hi Vijaya

Thanks for your reply

So you mean just need to connect LVSCKE_P/N of PTN3460 with DS90UB947 and LVSCKO_P/N of PTN3460 could be floating in dual Pixel mode ,is it correct ?
