Offering 4x the ESD Protection of Competitive Solutions, Intersil's ISL54230 Provides Simple, Space-Efficient Way to Interconnect Baseband Chip, Application Processor, Internal SIM Cards and Other Support Chips in Full-Featured SmartPhones
MILPITAS, CA -- (Marketwire) -- 07/24/09 -- Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of analog and
mixed-signal semiconductors, today announced the
ISL54230, a new octal switch that is ideally suited for high-end cell
phone applications. The ISL54230's small size and flexibility allows
designers to optimize the routing of the many different types of signals
found in
high-feature-set cell phone products.
The ISL54230 has 8 individual Single Pole Double Throw (SPDT) switches
whose performance has been carefully designed to enable them to pass a wide
range of precision voice and data signals, including high-speed USB, UART,
PCM, audio and power. With the addition of simple logic control, the
switches can be configured to multiplex between pairs of signals like USB
2.0 high-speed ports, or between groups of signals like SIM card clock,
data and power lines. To minimize board space, the signal pins on the
ISL54230 have been arranged in a 'flow-through' manner to avoid signal
crossovers on the PCB. Unused switches can be powered down as required
under logic control.
For dual-mode cell phones, the ISL54230 allows dual baseband chips to
access either of two SIM cards while allowing the unused SIM card to be
powered down in order to minimize battery drain.
