How much Jitter can a Clock Cleaner Clean... ?
I need to provide a low jitter <0.5ps rms clock for ADC conversion, and I have a "dirty" clock source with about 1ns jitter. Can this be cleaned, and which part would be recommended.
Yes, for sure! You need a VCXO based jitter cleaner, such as:
CDCM7005 (5 outputs, excellent power)
CDCE72010 (10 outputs, EEPROM)
LMK04800 family (dual loop architecture, allows you to buy a lower frequency VCXO if you need a particularly high ADC clock frequency)
Thanks for the info. These parts seem suitable, especially the LMK04800 with a xtal and varcap diode option to reduce cost.
But I couldn't see any info on Jitter Tolerance. For example the Si53xx family shows a Jitter Tolerance of 5000/BW ns p-p, where BW = 120Hz, giving Jitter Tol = 42 ns p-p.
Is the any info on the Jitter Tolerance for the Ti parts?
