Intersil Unveils ISL54222A Integrated Circuit Intersil Corporation has introduced an integrated circuit that offers features for portable products where internal USB high-speed ports may need to share a single USB connector. The ISL54222A is also bidirectional and allows the sharing of a host USB port between multiple outputs such as in desktop or laptop computers, portable mini printers or docking stations. It is a single-supply USB 2.0 high-speed multiplexer that can operate from a single 1.8V to 3.3V supply. In addition, the device features human body model (HBM) electrostatic discharge (ESD) performance of more than 12kV on input/output (I/O) terminals. This combination of low supply voltage and high ESD protection makes the device flexible and robust for applications such as Smartphones, MP3 players, personal navigation devices and digital cameras. The product features internal charge pumps that lower switch resistance and open the USB eye for better performance at 480Mbps. ...

Intersil Unveils Flexible ISL54230 Octal Switch Intersil has introduced the ISL54230 Octal switch, which is suitable for high-end Smartphone applications. The ISL54230's small size and flexible design enable designers to optimise the routing of the many different types of signals in dual-mode, dual-standby operation phones. It is a quad double-pole/double-throw (DPDT) analogue switch that can operate from a single +2.0V to +5.5V supply. It contains eight single-pole/double-throw (SPDT) switches configured into four DPDT blocks. Each DPDT block is independently controlled by a logic input signal. This flexible configurability provides switching and routing of USB, UART, PCM for Bluetooth Phy, SIM power/data and audio signals between internal chips and external connector pins. In particular, the ISL54230 allows dual-baseband chips to access either of two SIM cards while allowing the unused SIM card to be powered down into a zero-power-consumption condition.
