Analog semiconductor company Inphi Corp. thinks it's ready to go public, partly on the promise of the 100-Gbit/s market.
Inphi filed its S-1 form with the Securities and Exchange Commission (SEC) today, listing a maximum offering price of $115 million.
It's part of a small spate of optical-related IPOs lately. NeoPhotonics Corp. (NYSE: NPTN) has its own S-1 on the books, and O-Net Communications (ShenZhen) Ltd. recently went public in Hong Kong. (See NeoPhotonics Readies Its IPO and Optical Firm Preps Hong Kong IPO.)
Inphi counts itself in the optical space, too. Founded in late 2000, the company originally targeted its indium phosphide (InP) chips at 40-Gbit/s networks.
But it had to retrench after the crash. Most of its revenues now come from memory-interface chips, with Samsung Electronics Co. Ltd. (Korea: SEC) and Micron Technology Inc. (Nasdaq: MU) representing 36 and 17 percent of revenues last year, respectively. Samsung even owns 6.9 percent of the company.
Revenues have been flat since 2007, but Inphi became profitable in 2009, with net income of $7.3 million on revenues of $59.9 million.

For its first quarter of 2010, which ended March 31, Inphi reported net income of $12 million on revenues of $19.1 million.
In the 40- and 100-Gbit/s markets, Inphi sells chips that get tucked away in optical interface modules or on linecards: transimpedence amplifiers, modulator drivers, clock-and-data recovery chips, and serializer/deserializers (better known as SerDes). (See Inphi Celebrates Life After 40-Gig.)
The company still spends quite a lot on research and development. R&D spending has stayed at just less than $18 million for each of the past three years, even as revenues have grown. That still represents about 30 percent of revenues.
Inphi's sales to Korea have been substantial, thanks to the Samsung relationship, but sales to China have grown rapidly, to $9.9 million last year compared with $2.3 million in 2008.
The top three investors in Inphi are venture firms: Walden (holding 20.8 percent of shares), Tallwood (20.5 percent), and Mayfield (18.6 percent).
Underwriters for the IPO are Morgan Stanley , Deutsche Bank AG , Jefferies & Company Inc. , Thomas Weisel Partners , and Needham & Co.
