There are a couple of errors in the article.  References to 33W resistors should of course be 33Ω - the symbol font in my Word doc got ignored.   And the schematic shows these as 39Ω  - which is what I think I eventually used - they give a slightly lower charge rate of 62 - 23 mA. 

Thanks for the comment, Docdivicar!

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
