RF noise suppression enhanced in IR receiver modules

3rd April 2018

New Yorker Electronics has begun distribution of Vishay Intertechnology’s next generation miniature IR receiver modules for IR remote control applications. The devices in the Vishay Semiconductors TSOP11xxx, TSOP12xxx, TSOP13xxx, TSOP14xxx and TSOP18xxx families deliver improved dark-ambient and disturbed-ambient sensitivity to infrared signals, as well as improved suppression of RF noise.

The IR receivers provide increased robustness against disturbances such as IR emissions from CFL lamps and RF emissions from on-board Wi-Fi antennas.

Applications for these infrared (IR) remote control units include televisions, set-top boxes (STBs), audio systems, air conditioners, video projectors, cameras and video game systems.

Suitable for codes demanding even the tightest pulse-width specifications, such as SIRCS and RCMM, they display improved pulse-width accuracy for lower bit error rates and are insensitive to supply voltage variations and ripple noise – leading to more simplified designs.

Available in cast, mould, minimould, and minicast packages, they feature a photodetector, preamplifier circuit and an IR filter in a single 3-pin epoxy package.
