Vishay Intertechnology Launches Infrared Receivers Compliant to 3DTV CEA-2038 Command-Driven IR-Synchronized Active Eyewear Standard
Per the standard, the receivers are designed to operate on a carrier frequency of 26.2 kHz, which is lower than that used by standard remote control systems and thus helps avoid possible interference from TV and set-top box remote controls. The TSOP75D26 and TSOP35D26 are also designed to receive the 3D synchronization signals from an 830 nm emitter, further avoiding the possibility of interference. They are compliant with the standard’s long encoding command sequence which features better immunity in noisy environments. Like all of Vishay’s IR receivers, the TSOP75D26 and TSOP35D26 feature industry-leading suppression of optical noise from compact fluorescent lights, LCD backlights, and plasma panels.
The TSOP75D26 and TSOP35D26 integrate a photodiode, amplifier, automatic gain control, band pass filter, demodulator, and control IC into a single tiny package which helps minimize the weight of 3D glasses, while their ultra-low current consumption maximizes the battery life. The TSOP75D26 and TSOP35D26 are surface-mount devices that can be mounted in a side or top view. They both have a viewing angle of ± 50° which allows for significant head movement without signal loss. The TSOP75D26 measures 2.3 mm x 3.0 mm x 6.8 mm and has dual lenses while the TSOP35D26 measures 4.0 mm x 5.3 mm x 7.5 mm and has a single lens.
Samples of the new TSOP75D26 and TSOP35D26 are available now. Production orders have a lead time of six to eight weeks.
