Vishay launches a new generation of micro-infrared receivers, with higher sensitivity, noise suppression capability and pulse width accuracy

"Vishay introduces a new generation of micro infrared (IR) receiver module for infrared remote control. Vishay semiconductors tsop11xxx, tsop12xxx, tsop13xxx, tsop14xxx and tsop18xxx series devices not only improve the sensitivity to infrared signals in dark and noisy environments, but also have better ability to suppress RF noise. The device has very high pulse width accuracy, which is suitable for application scenarios with strict coding requirements, and even the most stringent pulse width standards such as sircs and RCMM. The device released today can be used for infrared remote controls in televisions, set-top boxes, audio, air conditioners, video projectors, cameras, game consoles and other products. For the remote control function in these products, these devices enhance the resistance to various interferences, such as the infrared radiation of mercury lamp and the RF radiation of Wi Fi antenna on the circuit board. In addition, the module improves the accuracy of pulse width, can achieve lower bit error rate using almost any coding, and the device is not sensitive to power supply voltage fluctuation and ripple noise. In order to simplify the design, the receiver integrates the photodetector, preamplifier circuit and infrared filter in 3pin epoxy cast (tsop1xxxx), mold (tsop12xxx and tsop14xxx), minimold (tsop13xxx) or minicast (tsop18xxx). The carrier frequency of each series ranges from 30kHz to 56khz, and there are 6 automatic gain control (AGC) versions for short burst and long burst coding. The power supply voltage of all receivers is 2.5V ~ 5.5V, the power supply current is small, meets RoHS and Vishay green standards, and is halogen-free. The new infrared receiver module can now provide samples and has achieved mass production. The supply cycle is four to six weeks.
