4pc: Motorola MC100EL33  ÷4 Frequency Divider: Dual flipflop up to 4GHz Toggle ECL 5V Prescaler SOIC-8

On offer are several lots, each of 4 new (old stock) pieces of the MC100EL33 4GHz frequency divider by On-Semi (formerly Motorola).

If you want to measure or control frequencies beyond 50..100MHz, you'll need to use more specialist circuitry than the regular 74' series counters and flipflops. These ECL dividers are an example, a dual flipflop capable of toggling at microwave frequencies.
  • max toggle, 4.2GHz typical, 3.8GHz guaranteed.
  • 1pS jitter
  • rise/fall times ~220pS
  • propagation delay 700pS
  • internal bias Vbb voltage generator
  • differential/single-ended/AC coupled input configurations
  • temperature compensation
  • 8 pin SOIC - easily hand soldered
These dividers would complement many other prescalers (with inputs to around 1GHz) quadrupling their range. For instance, the MC12080 ÷10, 1GHz divider, or the 1GHz NEC uPB565C. A MMIC would be a good choice as a front end amplifier for this divider, for measuring weaker signals. Alternatively they're easy to cascade for ÷16, ÷64 etc.

In October 2006 Silicon Chip magazine published a ÷1000 prescaler project by Jim Rowe which uses a similar configuration (with non-temp-comp 10K series brother, the MC10EL33 and an ERA-2SM); see photos for schematic details.

About the Seller : RFPlus

I'm Jon, a lifelong hobbyist, professional engineer and now occasional seller on Ebay, having sent over 10,000 items around the world over the past 17 years. I am not a business/company despite Ebay's classification to the contrary, though I do have a lot of parts and gear which should go to a good home.

All parts for sale are my private property, in stock in Cornwall, Southwest UK, and ready to post to the world via Royal Mail, or if larger/heavier via your arrangement/collection. I post via UK First Class post: my P&P charge is at cost but I'm happy to combine multiple items in a package for that one charge. You may need to use the Ebay Cart (and request a total if Ebay miscalculates).

If there's a problem with anything, I can send a replacement order, refund your money or do whatever it takes to make you happy. I hope my feedback gives you the confidence that I'm good to deal with. Any questions, please ask!
