I would like to consult all experts on which prescaler should I use, below are my requirements:
1. Input Freq Range: 0/1.25GHz to 4GHz (PCIe speeds) to reduced to min 800MHz. I need flexibility so div-by-2/4/8 ...
2. Type of Input: Clock and/or PRBS
Appreciate all your feedback.
Can this device accept PRBS data as input rather than clock-like pattern?
Any other device recommended?
I got the HMC862A eval board. Did few measurements and saw that the eye height measured at HMC862A is higher than expected. Any comments/feedbacks why I see such results?
Clock Pattern @ 4GHz with No De-emphasis.
