Vishay Semiconductors TSOP75D25 / TSOP35D25

IR Receivers for 3D TV

Features 25 kHz Carrier Frequency

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. The Vishay 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. These IR receivers receive modulated synchronization signals, meaning a single emitter can be used in the TV to achieve transmit distance of over 26 meters.
