Intersil’s Compact New Single Pole/Triple Throw Switches are Industry’s Top Solution for Eliminating Handheld Device Connector Congestion in Smart Phones, PDAs, MP3/4 Players
ISL54214 and ISL54217 Combine Low Distortion, Dual USB Ports, for Maximum Efficiency --
MILPITAS, CA, April 1, 2009 – Intersil Corporation
(NASDAQ Global Select: ISIL), a world leader in the design and manufacture
of high-performance analog and mixed signal semiconductors, today introduced
two new switches that provide the industry’s optimal solution for eliminating
congestion in handheld device connectors.
The new ISL54214 dual SP3T (Single Pole/Triple Throw) switch or 3:1 Mux combines
low distortion audio and two accurate USB 2.0 high speed data (480Mbps) signal
switching paths in the same low voltage device. The switches enable
use of a common mini USB or audio headphone connector in media players and
other portable battery-operated products by allowing either two USB transceivers
or one USB transceiver -- plus a UART transceiver -- to share pins with an
audio codec.
The ISL54217 dual SP3T adds Intersil’s comprehensive click and pop elimination
circuitry to the switch, enhancing the performance of handheld products by
removing audio artifacts.
The audio switch cells in both the ISL54214 and ISL54217 can pass ±1V
ground referenced audio signals with ultra low distortion of <0.03 percent THD+N
when driving 5mW into 32 Ohm headphone loads. In addition they have a special
Muting mode of operation to provide very high isolation between the codec
and the headphone or amplifier load. The USB switch cells have very low ON
capacitance of just 8pF, resulting in high bandwidth to move USB high speed
signals with minimal edge and phase distortion.
Dual USB 2.0 data paths allow multiple chips to share a high speed USB port. Both
devices incorporate failsafe power-off protection to prevent USB lock-up or
battery drain via USB ports in case of power failure. COM pins in each version
can tolerate over voltages beyond the supply rails, meeting USB short circuit
requirements with no additional components.
Pricing and Availability
Both new devices are now available in tiny packages that save space – each
is 65 percent smaller than any competitive device. The ISL54214 is now available
in 12-Lead 3mm x 3mm TQFN packages, and also 12-Lead 2.2mm x 1.4 mm ultra
thin QFN packages. Prices start at $0.71 each in 1,000-piece units. The
ISL54217, which incorporates Intersil’s click and pop elimination circuitry,
is available in the same package options, with prices starting at $1.21 each
in 1,000-unit quantities.
