LMH0346: Is it possible to use SCO output of 1st LMH0346 for EXT CLK input of 2nd LMH0346?

K.Yaita

Part Number: LMH0346

Hi Team,

My customer consider to use two LMH0346 with one crystal.
He assumed the following scenario.
- a crystal is connected to 1st LMH0346
- use SCO (output) of 1st LMH0346 for EXT CLK (input) of 2nd LMH0346
Is the scenario reasonable?

If it is possible, he want to know how to configure the schematic.

Best Regard,
Yaita

Hi Yaita-San,

SCO runs at data rate clock and this cannot be done.
