determine PLL requirements for ADC
Jun 30th, 2013, 11:52pm
 
Hi all,

I'm starting a new position doing mixed-signal design. So far I've only worked in RF/Analog. I need to know how I can calculate PLL requirements for a baseband ADC based on modulation/sampling rate etc. Does anybody have any good links?

thanks,
Aaron

hello,
In-general cycle to  cycle jitter matters for an ADC, because error in the sampling time instant will leads to SNR drop.
The following pap has some points   ....
1. Specification Driven Design of Phase Locked Loops
2. http://www.maximintegrated.com/app-notes/index.mvp/id/800

Thanks,
Raj.
