Fairchild Semiconductor's USB 2.0 transceivers target consumer applications and ultra-portables. The new devices tout ESD protection and compact packaging that are specifically designed for today's products.

The USB1T1102 and USB1T20 offer designers an "off-the-shelf" USB 2.0 solution for electrical compliance. The USB1T20 device in fact can be used as an alternate source (a drop-in replacement that is) for transceiver migration from USB1.1 to 2.0.

Both transceivers provide high ESD protection ratings of 15kV. Their ultra-small MLP packaging (3-by-3mm 16-lead or 2.5-by-2.5mm 14-lead), combined with built-in protection features, make these products suitable for applications such as cellphones, digital cameras and portable video devices.

The USB1T1102 full-speed (FS) transceiver incorporates onboard voltage regulation and voltage level translation. This device consumes <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.

The 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 product offers drop-in electrical migration from USB1.1 to 2.0 and is an excellent low-cost option for space constrained applications that do not require a voltage regulator. The USB1T20 is available in both 14-lead MLP and 14-lead TSSOP packaging.

In 1000-piece lots, the USB1T20A is priced at 65 cents, and the USB1T1102 at $1.04. Samples are already available, with production quantities having a four week lead time. Additional information can be found online.
