Eindhove, The Netherlands -- Royal Philips Electronics has introduced a Universal Serial Bus (USB) On-The-Go (OTG) transceiver chip providing direct between iappliances such as mobile phones, cameras, video recorders and PDAs.

The Philips ISP1301 transceiver can transmit and receive serial data at both full-speed (12 Mbps) and low-speed (1.5 Mbps) data rates, allowing a device to adjust data transmission speeds depending on the application, thus saving precious battery power.

As the newest addition to the Philips family of USB OTG chips, the ISP1301 transceiver allows digital devices to connect directly to one another, without the use of a PC, to perform basic functions such as printing a photo or transferring a message from a digital phone to a PDA.

The Philips transceiver allows USB application specific ICs (ASICs), programmable logic devices (PLDs) and any system chipset with USB host/device function built-in (but without the USB transceiver) to interface with the USB physical layer. Philips' complete range of USB OTG semiconductors are fully compliant with the USB Implementers Forum's (IF) OTG Supplement to the USB 2.0 Specification.

In addition to the new transceiver chip, Philips also offers a single-chip USB OTG controller (the ISP1362) and a complete USB OTG system developers kit.

The ISP1362 is an OTG compliant USB 2.0 host and peripheral controller, allowing the chip to act as USB host, USB peripheral, or both functions simultaneously. The system developers kit, based on Philips OTG semiconductors, simplifies the addition of USB OTG to handheld and mobile devices using the Intel® PXA250 applications processor with Intel® 4 XScaleTM technology.

Available in the very thin HVQFN24 package, samples of Philips ISP1301 transceiver are immediately available. Volume production will begin in Q2 2003. The Philips USB OTG developers kit is currently available from Philips.
