Due to EMV constraints and our used display we can run the clock (TxClkin) only at 6MHz. The DS90C385AMT generally works with that frequency, but it is out of the specification (18 - 81.5 MHz). In some cases the display won't work as desired.
Are there alternative LVDS driver chips (sender and receiver) which can be run at lower frequencies? Any ideas why the DS90C385AMT doesn't work properly at 6MHz?
