Two new USB 2.0 transceivers offer exceptional ESD performance and compact packaging, and are specifically designed for today's ultraportable and consumer applications.

The USB1T1102 and USB1T20 offer designers an "off-the-shelf" USB 2.0 solution for electrical compliance, while providing high ESD protection ratings of 15kV.

The USB1T20 device is the world's first alternate source (drop-in) replacement for transceiver migration from USB1.1 to 2.0.

Both transceivers can easily withstand adverse ESD events, eliminating the need for external ESD protection.

Their ultrasmall MLP packaging (3 x 3mm 16-lead or 2.5 x 2.5mm 14-lead), combined with built-in protection features, make these products ideal for applications such as cellphones, digital cameras and portable video devices.

"Fairchild's new USB transceivers offer industry-leading performance, simplifying designs and eliminating the need for additional components", said Chris Ferland, Fairchild's USB Marketing Manager.

"These products minimise time to market, save board space and reduce total implementation cost - all of which are vital considerations for today's ultraportable applications".

"Fairchild's newest transceivers make it easy for designers to transition to the newest 2.0 requirements by offering drop-in replacements for USB1.1 applications".

Fairchild's USB1T1102 full speed (FS) transceiver incorporates onboard voltage regulation and voltage level translation.

This device consumes less than 6.6mW of power from the local supply and is well suited to battery-powered applications.

The USB1T1102 offers the first drop-in replacement transceiver for standard 1102 MHBCC package footprints, as well as significant space savings with its ultra-compact MLP packaging.

Fairchild's USB1T20 is a low-speed (LS) and full-speed (FS) USB-compliant transceiver and is the first 2.0 transceiver offered without a voltage regulator.

This device offers drop-in electrical migration from USB 1.1 to 2.0 and is an excellent low cost option for space constrained applications that do not require a voltage regulator.

USB1T20 is available in both 14-lead MLP and 14-lead TSSOP packaging.
