The chip sector is pretty hot. Intel (NASDAQ: INTC) reported a respectable quarter this week, and the stock is near a 52-week high. Also close to their highs of the year are Texas Instruments (NYSE: TXN) and Advanced Micro Devices (NYSE: AMD).

Well, you can add Xilinx (NASDAQ: XLNX) to the list. The company, an expert on programmable logic, reported an earnings-beating quarter yesterday after the bell, according to Reuters. Xilinx made 23 cents per share in Q2, a penny ahead of analyst expectations. Revenue likewise was slightly ahead of the projections.

Xilinx (NASDAQ: XLNX), a tech entity involved in programmable logic and a colleague of companies like Actel (NASDAQ: ACTL) and Altera (NASDAQ: ALTR), issued a business update on Tuesday. Believe it or not, it contained some good news. How about that for a change? I'm sure shareholders were pleased.

According to this news item, Xilinx believes that its revenue picture should be better than previously thought. Sales should drop by somewhere between 13% and 18% for the March quarter on a sequential basis. Management had originally believed that they'd have to report a sequential revenue drop between 15% and 25%. So, yes, there will still be a decline, but hey, if it's less than expected, you gotta take that. It's too bad, though, that the gross margin range wasn't raised. It should still fall between 61% and 63%. If management had raised that as well, then I bet the stock would have closed even higher on the news. It rose almost 4% on better-than-average volume yesterday.

"The semiconductor industry has been under pressure now for sometime, but one of the fastest growing businesses within semiconductors has been in programmable logic devices (PLDs)," notes wireless sector specialist Nikhil Hutheesing.

In The Forbes Wireless Stock Watch, he explains, "One of the top companies in this business is San Jose, California-based Altera (NASDAQ: ALTR). Here's his bullish review.

"These PLDs are chips that allow software developers to use inexpensive software tools to quickly develop, simulate, and test their designs. Then, a design can be quickly programmed into the chip and immediately tested in a live circuit.

"Unlike other chips, PLDs are based on re-writable memory technology. That means that if a designer wants to change the design on the chip, the device can be easily reprogrammed.

"Once the design is final, customers can go into immediate production by simply programming as many PLDs as they need with the final software design file. The result is that a final design can be completed much faster and less expensively than that of a custom, fixed logic device.

"While Altera also manufacturers other kinds of chips, it's the PLD business that could really boost the company's business. Eventually, Altera plans to replace the ASIC business entirely with PLDs.
