Recently, Vishay Intertechnology, Inc. announced the launch of a new generation of miniature infrared (IR) receiver modules for infrared remote controls. Vishay Semiconductors TSOP11xxx, TSOP12xxx, TSOP13xxx, TSOP14xxx and TSOP18xxx series devices increase the sensitivity of infrared signals in dark and ridiculous environments, as well as better immunity to RF noise. The device's very high pulse width accuracy is ideal for coding-critical applications, even the most stringent pulse width standards such as SIRCS and RCMM.
The device released today is available for infrared remote controls in televisions, set-top boxes, audio, air conditioners, video projectors, cameras, game consoles and other products. For remote control in these products, these devices enhance immunity to a variety of disturbances, such as infrared radiation from mercury lamps and RF radiation from Wi-Fi antennas on the board. In addition, the module improves pulse width accuracy, achieves lower bit error rates with virtually any encoding, and the device is insensitive to supply voltage fluctuations and ripple noise.
To simplify the design, the receiver integrates the photodetector, preamplifier circuitry and IR filter in a 3-pin epoxy (TSOP11xxx), Mold (TSOP12xxx and TSOP14xxx), Minimold (TSOP13xxx) or Minicast (TSOP18xxx) package. in. Each series has a carrier frequency from 30kHz to 56kHz and has six automatic gain control (AGC) versions for short burst and long burst encoding. All receivers have a supply voltage of 2.5V to 5.5V, low supply current, RoHS and Vishay green standards, and halogen-free.
