Data Compression

One thing I did not make room for in the story was Exar's Pather chip (second generation coming this fall) and its acquisition whicvh adds unstructured data compression to it.

Seems to me like one of their m0ore promising and interesting products. Anybody have any insights on it and the area?

Thanks Rick for this interview. I think you've touched on some very pivotal issues, and for one agree completely with Louis' views.

It makes sense.  All of the various parts of the IoT need to communicate.  They'll be passing data around, and the data may be big.  Being able to compress it on the fly to reduce the bandwidth needed to send it is pretty much a necessity, and being able to encrypt it for security likewise. Having that capability means Exar can offer a more complete solutions portfolio.

I agree with DiNardo on fabs.  Given the enormous costs of building and updating them, anyone making chips has to ask "Do we need our own, or can we concentrate on design and contract with someone else to actually make our chips?"  The answer is almost certainly "Let someone else make them",  There are an enormous number of chips that don't require bleeding edge process technologies that someone like GlobalFoundries or TMSC can make with ease, and your only concern will be "Who has the capacity to fill my order in the desired time frame?"

I was amused by his comment "At Crosslink Partners, seven of us reviewed 1,200 business plans a year, held 300 meetings, did deep diligence on 60 companies, and then made six investments, which means a partner in a good year did one deal. It wasn't enough to keep me busy and excited."

Reviewing 1,200 business plans, holding 300 meetings, and deep diligence on 60 companies sounds like more than enough to keep the average person entirely too busy.

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.
