Fairchild Semiconductor's New Low-Power Dual Analog Switch Exceeds ``USB 2.0 High Speed'' Bandwidth Requirements.

SOUTH PORTLAND, Maine -- Wide bandwidth analog switch exceeds 3rd order harmonic for "cleaner" USB 2.0-compliant signals in ultra-portable and consumer applications

Fairchild Semiconductor (NYSE:FCS) announces the FSUSB22 low-power, high bandwidth dual analog switch. The FSUSB22 is the ideal choice for high-speed USB switching in ultra-portable design applications by virtue of its combined low power (less than 1uA), wide bandwidth (greater than 720 MHz) and small (DQFN) package. Moreover, the FSUSB22's wide bandwidth allows passage of 3rd harmonic frequencies critical for maintaining maximum signal integrity with minimal distortion, jitter and phase noise. Designed specifically to exceed the 240 MHz minimum bandwidth requirements of the new USB 2.0 "High Speed" standard, typical

FSUSB22 switching applications include next-generation cell phones, digital cameras, set-top boxes, computer games, printers, notebooks and other emerging USB 2.0 High Speed-compliant devices. Configurable either as a dual DPDT (Double Pole / Double Throw) switch or four-channel 2:1 multiplexer / de-multiplexer for USB 2.0 connector sharing or port isolation, the FSUSB22 offers design engineers flexible options for various ultra portable applications.

The 2.5 x 3.5 mm DQFN package offers a 75% space savings over standard TSSOP packages. The elimination of leads in the DQFN package lowers capacitance and inductance, which results in lower noise and crosstalk between the I/O terminals. Further, the exposed die attach on the bottom of the DQFN package improves the thermal performance of the device.

Other key features of the FSUSB22 USB 2.0 analog switch include:

--Exceptionally wide bandwidth (greater than 750 MHz; -3 dB) ensures greater signal fidelity by minimizing edge and phase distortion;

--Less than 1uA (maximum) quiescent current consumption contributes to extended battery life;

--Low On Resistance (RON) of 5 Ohms (typical) reduces noise level;

--Greater than 4 kV ESD performance for Human Body Model (HBM);

--USB High Speed (480 Mbps) and Full Speed (12 Mbps) signaling capability.

"As the leading supplier of USB 2.0 High Speed switches, the FSUSB22 sets the standard for smaller size, lower power and wider bandwidth solutions for the emerging generation of ultra-portable USB 2.0-compliant devices," said Gerald Johnston, Fairchild product manager for analog switches. "The FSUSB22 exemplifies Fairchild's commitment to meet the continuing demand for innovative technology solutions that provide the performance and value that OEMs need to take their ultra-portable designs to the next level."

The lead-free (Pb-free) FSUSB22 meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B and is compliant with European Union requirements.
