Infrared Receivers

Infrared Receivers are widely used in conjunction with a remote control handset to provide remote functionality for a wide range of consumer goods – Tv’s, Set Top boxes, Air Conditioners, Lighting control, DVD Players are a few common applications, but the list is growing all the time.

The system relies on a transmitting IR LED in the remote control sending a coded pulse train to the main unit (TV,DVD etc). This is received by the IR Receiver module which contains a PIN Photodide which receives the initial signal. This is then conditioned by a built in pre-amplifier and then output via an Integrator and wave shaper circuit.

Selectronic can now offer a complete range of IR Receivers to cater for all remote control to front panel communication needs. The range includes both surface mount and through Hole type devices.

These parts cover all the popular operating frequencies of 32.7,37.9,40, and 56.7 kHz. And operate from -20 to 80 °C.

Product Testing

Of course for Selectronic to offer these parts we have to be sure they will operate in the worst case conditions for such parts. These include being subject to harsh Fluorescent lighting – which when used with electric ballast can produce significant electromagnetc interference.

Surprisingly TV’s themselves can be a source of interference, with Plasma types being the worst for this. We have verified the performance of these parts under the above conditions – so we are sure the parts are fit for your application!

IR Receiver Testing Set up

 

Image top right: about 500 Lux when luxmeter faces front.

Image middle right: about 1000 Lux when luxmeter faces top

Images bottom: The test station is illuminated with both tube and CFL lighting to produce a worst case interference environment. Osram and Hippo 36W CFL. Philips 36W tube and Electric Ballast.

Set-Top Box and TV Testing

The devices under test were fitted to a STB, which was connected to a selection of different TV’s. STB and TV are mounted onto a turntable so tangential beam angles could easily be set up.
