Intersil High-Speed Voice and Data Switches Deliver Superior Audio Performance while Eliminating Clicks and Pops in Handheld Products
Intersil’s ISL54210 and ISL54211 Combine Low Distortion Audio, USB 2.0 High-Speed Data Capability along with the Industry’s Best “Click and Pop” Elimination Technology in Compact, Low Power Devices
MILPITAS, CA, Jan. 19, 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
the ISL54210 and ISL54211, highly-integrated devices that extend Intersil’s
leadership position in compact, high-performance mixed audio and data switches.
The ISL54210 and ISL54211 combine superior low distortion performance, high-speed
USB 2.0 data rates and use the industry’s most effective suppression
technology to eliminate clicks and pops in handheld devices.
The new switches integrate Intersil’s MP3/USB 2.0 high-speed data interconnect
and ultra low distortion audio switching technology along with advanced ‘click/pop’ elimination
circuitry in a tiny micro TQFN package. The device allows audio and data paths
in small handheld products such as MP3 players and smart phones to share a
common mini-jack or mini-USB connector, freeing up connector pins for other
functions or eliminating the need for additional connectors. Incorporating
USB 2.0 high speed interconnect capability shortens digital audio file download
and synchronization times, while a high off-isolation mute mode eliminates
annoying clicks and pops during power up and power down. These features
enable the ISL54210 and ISL54211 to deliver a low cost, compact solution for
congested connectors in handheld products such as MP3 players and cell phones,
as well as docking stations.
The ISL54210 is optimized for powering off an LDO regulator and includes circuitry
for the detection of the USB VBUS voltage, which is used to switch between
the audio and USB signal sources. The ISL54211 can operate off a Lithium Ion
battery supply, and has logic control pins that are 1.8V logic compatible,
allowing for direct control via a standard microcontroller.
Pricing and Availability
The ISL54210 and ISL54211 are available now in 1.8mm x 1.4mm x .50 μTQFN
packages, with prices starting at $1.11 each in 1,000-piece quantities. A
10 Ld 3 x 3 TDFN version is priced at $1.07 each, and the 10 Ld 3 x 3 TDFN
T+R version is priced at $1.11 each, both in 1,000-unit quantities.
