( 01 Nov 2005 )
Royal Philips Electronics family of Universal Serial Bus (USB) and USB On-the-Go (OTG) carkit transceivers offers manufacturers a simple and cost-effective way to connect mobile devices to a carkit via a USB interface. Providing a single, simple connection for the processing of digital data and multiplexed audio for mobile applications, the transceivers also support smart carkit applications such as push-to-talk and caller ID displays. Product designers now have a f lexible and cost-effective way to add carkit support for mobile phones without having to change the design of the handset. The transceivers are compliant with the Consumer Electronics Association Mini-USB Analog Carkit Interface specification (CEA-936-A) and with USB specification revision 2.0. Philips’ ISP1109 supports USB and carkit interfaces in mobile applications. The ISP1302 supports OTG connectivity and features a 50milliAmp charge pump. Both devices are currently in volume production.
