Vishay – New VSOP98260 Remote Control Code Learning IC

Vishay Intertechnology, Inc. (NYSE: VSH) announces the industry’s first remote control code learning IC to integrate signal detection and processing into one component.

Optimized for universal remote controllers, tablet PCs, and smart phones, the VSOP98260 simplifies the code learning process by amplifying and shaping the signal received by the infrared emitter already present in these devices.

Product Benefits:

  • Supports a more intuitive code learning process for the consumer
  • Integrates signal detection and processing, eliminating the hassle of using discrete components
  • Output accurately corresponds to the carrier frequency and data burst length of the input signal
  • Immune to noise from other light sources like compact fluorescent lamps
  • Packaged in a small 2 mm by 2 mm QFN package with a low height of 0.7 mm
  • RoHS compliant
  • Halogen free
  • Compatible with lead (Pb)-free soldering

The Key Specifications:

  • Carrier frequency: 20 kHz to 60 kHz
  • Supply Voltage: 2.0 V to 3.6 V
  • Supply current: 0.6 mA to 0.9 mA
  • Temperature range of – 25 °C to + 85 °C. Market

Applications:

  • Control code learning for universal remote controllers, tablet PCs, and smart phones

The Perspective:

In order to transmit valid commands, universal control devices must learn the modulation frequency and pulse patterns for each appliance being controlled. The most intuitive method for teaching them the correct code is to use the appliance’s remote control, placing it nose-to-nose with the universal controller. When a key is pressed, the infrared emitter transmits the pulses associated with this function and the universal controller receives the code and stores it in memory.

The VSOP98260 simplifies the code learning process by amplifying and shaping the signal received by the infrared emitter already present in these devices. By combining these functions into one component, the IC simplifies designs in universal control devices, saving space and reducing overall costs.
