USB 2.0 multiplexer reduces connectors and improves cradle functionality in portable devices
Intersil has introduced the ISL54200 USB 2.0 high/full speed multiplexer. With a wider supply voltage range, higher bandwidth and better insertion loss characteristics than the competition, the device 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
In automotive applications where portable products are often placed in a cradle, a common cradle connector can serve multiple portable products with differing data signalling interface requirements while retaining a common USB cable connection to the automobile electronics. And, when used in a laptop docking station it allows a single USB host connection to provide two data ports serving external devices having high speed or full speed USB signalling capability.
Beyond flexibility, the ISL54200 also provides unmatched performance. The 800MHz of bandwidth and superior RON flatness delivers a wider eye opening for improved signal transmission. The industry-leading 80nanoAmps of quiescent supply current significantly lowers the battery drain, while the 2.7V to 5.5V supply voltage range allows a wider range of rail-to-rail signalling protocols while eliminating the need for an additional LDO power source.
Applications that will benefit from Intersil’s advanced technology include MP3 and personal media players, cellphones, PDAs, laptop and digital camera docking stations and cradle devices for cellphone, MP3 player and portable automotive or marine GPS devices.
The ISL54200 is now available in tape-and-reel quantities of 100-1,000 in a 10-lead μTQFN package. The product comes in bulk in a 10-lead TDFN package.
