IR Receiver Modules are immune to ambient light disturbances.

Press Release Summary:

Capable of operating over distances up to 114.8 ft on supply voltages as low as 2.7 V, TSOP3xxxx multi-function IR receiver modules combine PIN diode and preamplifier in one epoxy package measuring 6.95 x 6 x 5.6 mm. Integrated Automatic Gain Control circuitry suppresses light-source disturbances, internal metal shielding protects against electrical field disturbances, and internal band filter allows PCM frequency operation. Maximum data rate is 4,000 bit/s.

Vishay's Next-Generation IR Receiver Modules Provide 3-V Operation Over Distances of 35 m With High Immunity to Ambient Light Disturbances

MALVERN, PENNSYLVANIA - June 24, 2003 - Vishay Intertechnology, Inc. (NYSE: VSH) is adding to its family of multi-function IR receiver modules for the remote control market with 14 new devices that provide high immunity to ambient light disturbances while operating over a distance of 35 m (114.8 ft.) on supply voltages as low as 2.7 V.

The new TSOP3xxxx receiver modules from Vishay Semiconductors combine a PIN diode and preamplifier in a single package measuring just 6.95 mm by 6 mm with a height profile of 5.6 mm, allowing designers to develop highly integrated, space-saving IR remote control systems for end products including toys, televisions, DVD players, VCRs, and other battery-powered, remote-controlled products.

The module's epoxy package doubles as an IR filter, while integrated Automatic Gain Control (AGC) circuitry suppresses all kinds of light-source disturbances. Internal metal shielding protects against electrical field disturbances, and an internal band filter allows PCM frequency operation. The new receiver modules are specified for a supply voltage range of 2.7 V to 5.5 V and serve as the standard receiver in remote controls with a 3-V voltage supply.

Devices in the TSOP3xxxx series can operate with all common data formats, featuring a maximum data rate of 4000 bit/s. A demodulated output signal that can be directly decoded by a microprocessor facilitates use of the module in multimedia applications. TSOP3xxxx devices are TTL- and CMOS-compatible.

Samples and production quantities of the new TSOP3xxxx receiver modules are available now, with lead times of 6 to 8 weeks for larger orders. Pricing for U.S. delivery in 100,000-piece quantities starts at $40.00 per 100 pieces.

Vishay, a Fortune 1,000 Company listed on the NYSE, is one of the world's largest manufacturers of discrete semiconductors (diodes, rectifiers, transistors, optoelectronics, and selected ICs) and passive electronic components (resistors, capacitors, inductors, and transducers). The Company's components can be found in products manufactured in a very broad range of industries worldwide. Vishay is headquartered in Malvern, Pennsylvania, and has plants in sixteen countries employing over 25,000 people. Vishay can be found on the Internet at
