Other Parts Discussed in Thread: LMH0346, DS25BR101

Hi,

I think LMH0346 has CML/LVPECL compatible input.

When interfacing DS25BR101 LVDS output to LMH0346 input, can you connect directly ?

If you need AC coupling capacitor between the two devices, what is the recommended value ?

Please give us advice.

Best Regards,

The DS25BR101 LVDS output can be DC coupled to the LMH0346 input. (AC coupling capacitors are not necessary.)

I would recommend simply placing a single ~100Ω resistor close to the LMH0346 input pins to terminate the differential line.
