Other Parts Discussed in Thread: LMX2571, CDCM1802
I am working on a new design that requires a clock that can swing from 1-2MHz all the way up to 40-50 MHz, and possibly higher down the road. In the past we've used the LMX2571 for generating signals, but the new low frequency requirement won't allow its use. The LMX2571 gets down to 10 MHz and I'm looking at using the CDCM1802 to get the rest of the way down to 1.25 MHz. Is this a reasonable approach, and if so is there a minimum frequency spec I need to be aware of that may not be clearly stated in the datasheet. For LVPECL outputs it lists 0-800MHz but I've found that sometimes the performance at the low end is not clearly called out.
Thanks.
