LMH13000: LVDS/TTL/CMOS logic input

Part Number: LMH13000

Could you give me more detail on LVDS/TTL/CMOS logic input, mainly how to setup EN and EP pins when using TTL 3.3V signal ?

    Hi Daniel, 

    You can bias the EN signal at mid signal level, 1.65V DC (although any voltage in between 0.1V to 3.2V at this pin will work but to make it symmetric and to avoid any false trigger because fo the over shoot in the TTL signal, keeping the EN pin bias voltage close to the mid signal level is better) and give the TTL input signal of 3.3V logic at the EP pin. By the way what's the TTL signal frequency you will be operating the device at?

    Regards
