Part Number: LMX2571
Other Parts Discussed in Thread: ADC3669, , LMX2572, LMK03318

Hi,
I have a TI ADC(ADC3669 not yet released) which requires clock source of jitter <100fs, one of the App engineer of TI has suggested me to use LMX2571

Kindly help in configuring the LMX2571 device for output of clock frequency of 500MHz

I have two such ADCs, can i use a single LMX2571 for dual 500MHz output simultaneously ?

if LMX2571 is not suitable kindly suggest a PLL based clock source to server the purpose

Hi Shyam,

What is the ADC clock format requirement? Differential or single-ended?

LMX2571 has two single-ended outputs. If differential clock is required, you may consider LMX2572.

Also what is the ADC clock phase noise requirement?

but LMX2572 is out of stock

how about using LMK03318 ?

Hi Shyam,

Stock availability is very dynamic, you can work with our sales team to fix this issue.

LMK03318 has 8 outputs, since you only need two outputs, it is a bit over-design with LMK03318.
