Intersil’s USB 2.0 multiplexer reduces connectors and improves cradle functionality

Intersil Corporation’s ISL54200 USB 2.0 high/full speed multiplexer has a wider supply voltage range, higher bandwidth, and better insertion loss characteristics. It provides the most flexible high performance solution for interfacing USB and non-USB portable devices.

The flexibility of the ISL54200 comes from its ability to switch between data sources having different data speeds and signal levels, and to output them through a common connector. When used inside a portable device such as cellphone it alternately allows chips with high-speed (480Mbps) USB circuitry and chips with lower speed UART or Full Speed (12Mbps) USB to communicate through a single connector. This allows access to slower parts of the cellphone product over a common interface. In automotive applications where portable products are often placed in a cradle, a common cradle connector can serve multiple portable products with differing data signaling interface requirements while retaining a common USB cable connection to the automobile electronics.
