Mouser Stocking New Vishay 3DTV Receivers

MANSFIELD, Texas — Mouser Electronics, Inc., known for its rapid introduction of the newest products, today announced it is stocking new product from Vishay Semiconductors.

The Vishay Semiconductors TSOP75D25 and TSOP35D25 are infrared receivers developed specifically for the LCD shutter glasses used with 3D-ready TV sets. The surface-mount TSOP75D25 and TSOP35D25 IR receivers are designed to be assembled into active 3D glasses, where they receive infrared signals from the TV set and ensure the glasses’ LCD shutters open and close in proper synchronization to create the 3D effect. Vishay Semiconductors TSOP75D25 and TSOP35D25 IR receivers are designed to operate on a carrier frequency of 25 kHz, which is lower than that used by standard remote control systems and eliminates possible interference from TV and set-top box remote controls. Because TV remote control emitters and receivers operate at a wavelength of 940 nm, the TSOP75D25 and TSOP35D25 are designed to receive the 3D synchronization signals from an 830 nm to 850 nm emitter, further eliminating the possibility of interference. The Vishay Semiconductors TSOP75D25 and TSOP35D25 integrate a photodiode, amplifier, automatic gain control, band pass filter, demodulator, and control IC into a single, tiny component that enables more streamlined designs for 3D glasses. Because the TSOP75D25 and TSOP35D25 operate at a carrier frequency of 25 kHz with a signal pattern featuring a minimum burst length of 6 cycles, a very high signal to noise ratio is achieved. Since these new IR receivers receive modulated synchronization signals versus baseband signals, a single emitter can be used in the TV to achieve transmit distance of over 26 meters.
