California Micro Devices Expands USB Port Companion Product Family

9/24/2002 - California Micro Devices announced it has expanded its extensive portfolio of USB port companion products with the PACUSBVB-Dx and PACUSB-Dx. The new Application Specific Integrated Passive (ASIPTM) devices integrate 11 discrete components into a single device, providing protection against electromagnetic interference (EMI) and electrostatic discharge (ESD). They also integrate the termination and pullup resistors required by the USB specification. The PACUSBVB-Dx offers the additional functionality of ESD protection for the USB Vbus. The products are ideal for downstream USB ports, such as those found in high volume set top boxes and game consoles.

"USB has moved beyond the PC and is becoming widely adopted across a variety of consumer devices," stated Joe Salvador, director of marketing for computing products at California Micro Devices. "Consumer applications such as set top boxes and game consoles are prone to EMI and ESD hazards. By integrating EMI filtering, termination, and ESD protection into a single device, we are able to help system manufacturers improve their quality and reliability while simultaneously reducing their overall manufacturing costs."

EMI filtering is required to ensure that high frequency emissions from a set top box or game console do not interfere with the operation of other consumer electronic products such as a television. It is also required to minimize interference that can be caused by external EMI radiation from devices such as cordless and cellular phones. The PACUSBVB-Dx and PACUSB-Dx provides EMI filtering across a broad range of frequencies providing greater than 20dB of attenuation beyond 1.5 GHz. It also provides industry leading 12 kV ESD contact protection, per the IEC61000-4-2 standard, protecting the system from damaging electrostatic discharge that often occurs when consumers are plugging in cables and touching exposed ports.

Key Features and Benefits
Designed specifically for USB downstream port applications, the new devices offer several key benefits:

Extensive Family of Solutions
USB has been widely adopted in a variety of markets for connecting peripherals such as printers and scanners to hosts such as PCs, notebooks, set top boxes and game consoles. The USB ports on peripheral devices are referred to as "upstream" ports. The peripheral devices are connected to "downstream" USB ports in hosts or expansion hubs.

Pricing and Availability
Samples and production quantities are available now. Pricing is $0.36 for the PACUSBVB-Dx in SOT23-6 package, $0.34 for the PACUSB-DX in SOT23-5 package, and $0.38 for the PACUSB-Dx in SC70-5 package, in quantities of 10,000.
