For example, special events like sweepstakes and contests raise call volumes significantly for a given number of days or weeks. EZ-Automatic Operator enables call centers to use additional ports for less than it would cost to add more ports to on-site IVR systems.

Santa Clara, Calif. – Vishay Siliconix's Si4838DY n-channel power MOSFET for low-voltage synchronous rectifier dc/dc applications is said to offer a 40 percent overall performance improvement in on-resistance and gate charge over competing devices, due to its 12-volt breakdown rating-one of the industry's first for low-voltage converter applications. It features a maximum on-resistance of 3 milliohms and a typical gate charge of 40 nC. For applications requiring more headroom, the company has released its Si4876DY, a 20-V device with 5 milliohms on-resistance and a gate charge of 55 nC, which offers a 10 percent improvement over competing devices.

The company expects revenue for the fourth quarter ended June 30 to be $14 million to $15 million and is projecting earnings per share to be near breakeven. Expenses are expected to be near flat when compared to expenses in the March 2001 quarter.

Designed to be used as local oscillators for RF and first IF of a dual conversion transceiver, the LMX23xxU series of dual PLL frequency synthesizers features six products: theLMX2330U, LMX2331U, LMX2332U, LMX2336U, and LMX2377U. The products in the family sport supply currents ranging from 2.5 to 3.5 mA. The entire family, exceptfor the LMX2335U, is available in CSP24 and TSSOP20 packages. The LMX2335U is available in CSP16 and TSSOP16 packages.

Clearly, the features needed for implementing DFT, such as controllability, observability and diagnosability must be incorporated into a design. DFT shouldn’t be an afterthought or a redesign activity. Designers must purposely create testable circuits. DFT is, however, more problematic than it appears. Let’s examine the hurdles and see what we can do to improve design activities for testability.

2. Inside GlobalFoundries’ Fab 8 — If you’re not working in IC design your opportunities to tour a state-of-the-art chip manufacturing site are few and far between. Fortunately, EE Times editor Jessica Lipsky was able to give you a virtual tour in her report on a facility in upstate New York. Nearly 40,000 of you came along. If you missed it before, now’s your chance to join in.

As communication data rates increase, maximum propagation distances over copper cable decrease. This trend is driving the use of fiber-optic links to shorter distances. Already well established in the telecom and datacom markets, optical fiber is now poised to find applications in the consumer and industrial markets.
