Bravo Microchip for extending the ECL lines.

I use quite a few of them like  SY100EL33L (div 4 ).  I needed a 400 MHz 
 >> 100 MHz divider for driving the CPU clock from the ADC clock.  ECL. 
yeah overkill.

(74)AC doesnt quite make it. Wow- newish 74AUC will go to 300 MHz at 
1.8V. ......

Anyway the SY100EL33L  is cheap. and 3.3V. ..even if the package is 
giant. (SOIC8) .

But I like the Wenzel  skip divider- now that is cool- Thanks BRUCE for 
posting that.  (http://www.wenzel.com/wp-content/uploads/dividers.pdf)
