LMX2582 input / output phase relationship

Other Parts Discussed in Thread: LMX2582

Hi,

I'm interested in using multiple LMX2582 to provide a clock to multiple channels; the device will be used in the integer mode, so that Fout = 4 * Fin. I'm wondering whether the phase relationship between Fin and Fout will be the same from power up to power up, across each LMX2582?

If this is not the case, is there another clocking chip / feature which can accomplish this?

thanks,

Marjorie

HI Marjorie,

We received your question. Thank you for your interest in our products. I forwarded this post to the applications engineer most familiar with this device.

Thanks,

Majorie,
There is no phase sync feature on this chip, so this relationship will not be consistent from power up to power up. However, you can adjust the phase.

WE have something in development that has the feature you want that is scheduled to RTM by the end of the year.
