Dear digital gurus:
We've developed a little frequency divider module (f/8 -f/128), and we'd
like to know how fast it will go. We suspect 10+ GHz on the input, since the
Hittite part inside is spec'ed at 13 GHz, but we don't have the equipment
necessary to drive it beyond 4 GHz.
If someone with better equipment could test this for us, we'll let you keep
the prototype module :)
You'd need:
1) 8-12+ GHz frequency source (the module requires ~-5 dbm/180 mVp-p to
drive the input)
2) A scope fast enough to see the outputs
3) A counter to verify the output
You get to keep:
i) The frequency divider pod
ii) AC adapter
iii) Several DC blocks
iv) Our eternal gratitude
We would like in return:
A) Scope captures at various input rates up to 12 GHz and fmax, where the
output fails
B) Verification of each available output ratio (f/8, f/16, f/32, f/64, and
f/128)
C) Some quantitative metrics on jitter, etc.
C) Qualitative commentary on the unit (usability, ergonomics, etc).
I would think this would less than an hour to set up and run, and
you'd get a very nice frequency divider in exchange.
Physically, it will look similar to this slower model:

but with one input and 4 complementary outputs. The input is single-ended
CML on an SMA, and the output is differential ECL, also on SMAs.
Act now! Supplies are limited to one :). Please let me know what equipment
you have at your disposal. Feel free to email me off-list if this is not
list-appropriate material. Then again, if it _is_ list-appropriate material,
I'd love to get feedback on what people want/need/value in a frequency
divider.
