Find the datasheet for SB99026MN and I'll send you $25!

Alright EEVBloggers, who can find me the datasheet for SB99026MN? It is from ON Semiconductors. If you can find it, I will send you $25 via PayPal.

I didn't have any luck, but if it helps ON Semi says the part was also named under PB99026MN and SB99026MNR2

I never imagined the high roller big YouTuber life would entail paying people to Google search for you.

Google search I can do. But perhaps someone out there may know this component specifically.

And magically for an obsolete part, you can still get 100,000pc with 2018+ lot code: http://sb99026mn.spot.ic37.com/

Did you send yourself $25?

Donated it to One Simple Wish.

did you actually replace the SB99026MN (a.k.a agilent 1822-1124) with the ONSEMI part?

[analogRF]

never mind
the pinout does not match the prescaler chip. input and output pins are visibly at very different locations

so NB7N017M can not replace the Agilent 1822-1124 prescaler. it's not the same chip.
it is probably a variation of that chip by onsemi made for agilent.

[analogRF]

by the way i think it was never mentioned in this thread that this chip is the main divider in the synthesizer section of the agilent MXG signal source. N5181,82, 71,72 etc...

[coromonadalix]

this one ?

[analogRF]

this one ?

yes. the picture seems to be from one of the variations of N5180-60xxxx board

I have a very weird and sort of intermittent unlock issue happing only at the low end of the VCO (at 750MHz-800MHz or so, no precise range )
still I cannot say its due to the prescaler chip. I also suspect the VCO itself which is one transistor and array of many varactors around it...
I have derived the whole pll circuit...search is ongoing...
