The Optoelectronics group of Vishay has introduced what is thought to be the industry’s first remote control code learning IC to integrate signal detection and processing into one component.
Optimised for universal remote controllers, the VSOP98260 simplifies the code learning process by amplifying and shaping the signal received by the infrared emitter already present in these devices. The IC can also be used in tablet PCs and smartphones that are enabled with an infrared emitter.
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.
Before the VSOP98260, signal detection and processing functions for code learning in universal control devices required discrete solutions. By combining these functions into one component, the new device simplifies designs in these devices, saving space and reducing overall costs.
The output from the VSOP98260 accurately corresponds to the carrier frequency and data burst length of the input signal while being immune to noise from other light sources such as compact fluorescent lamps.
The device can receive any carrier frequency from 20 kHz to 60 kHz, and it operates on a supply voltage from 2,0 V to 3,6 V and a supply current of 0,6 mA to 0,9 mA.
The IC is packaged in a small 2 x 2 mm QFN package with a low height of 0,7 mm. The RoHS-compliant device operates over a temperature range of 25°C to +85°C and is compliant to WEEE 2002/96/EC, free of halogens, and compatible with lead-free soldering.
