re: Price hikes, shortages hit chip market

I've been amazed at the TI "shortage". TI has claimed 20 week lead time on parts that have been on order since August 2009, and now say it will be July 2010 before they can deliver. Lead times of 1 year are ridiculous, it's almost as bad as being out of production but without and EOL notice. I've also been spammed by a half dozen parts brokers claiming to have plenty of TI stock. I wonder if brokers are buying up what little distributor stock is available. I used to consider TI a safe part to design in, but no more.

I started in this business in 1979 and have seen several of these "shortages" come and go. No doubt there were good reasons and I do not blame TI for how this began. But, their response was to create an even greater shortage and use it to bump prices. We use a lot of TI as they were one of my favorite go to vendors. We are now purging them as much as possible from future designs and re-spins in order to avoid this. We had this same issue with Maxim back in the late 90's & early 00's. They have yet to find their way back into my designs in any great numbers. Are you listening TI?

What else is happening in the supply chain? What other shortages do we have?

I have been in this industry since 1974 - I can remember the LS, TTL, HCT, HC, NAND, DRAM, Caps - shortages. This ons is very different and scary as it is NOT one type of material it is across the board - Vishay out 26+ weeks, TI 26+ On Semi 26+ NSC 26+ and just becasue you have parts on order it does not mean you will get them. Anyone want to discuss this can reach me at 949-333-5349 and I am happy to share what I know. Jim Scharfe

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.
