Hi folks,
I have recently designed a digital ASIC chip, tested the thing, and it works reliably at the 1.5GHz frequency it was designed for. All of testing was done at a lab, where I have access to all equipment you could ever ask for, including a clock generator that works in the GHz range.
My issue is that I have to demonstrate the chip operating outside of my comfy lab, meaning that I will have to provide a clock source. I want to build a PCB with discrete components that has its own clock generation. It cannot be a differential clock, I am bound to a CMOS signal. What solution would you use and how fast can I expect to operate? I have found some components that can do ~200MHz, but I was hoping to go higher. Ideas?
