Infrared Receiver Module IRM-37xxM3 Series Block Diagram Pin Configuration 1 2 3 1. OUT 2. VCC 3. GND Features ‧ High protection ability against EMI ‧ Circular lens for improved reception characteristics ‧ Available for various carrier frequencies ‧ Min burst length: 8 cycles ‧ Min gap length: 12 cycles ‧ Low operating voltage and low power consumption ‧ High immunity against ambient light ‧ High immunity against TFT and PDP backlight ‧ Long reception range ‧ High sensitivity ‧ Pb free and RoHS compliant Description The IRM-37xxM3 devices are DIP type infrared receivers which have been developed and designed by using the latest IC technology. The PIN diode and preamplifier are assembled onto a lead frame and molded into a black epoxy package which operates as an IR filter. The demodulated output signal can directly be decoded by a microprocessor.. Applications • AV equipment such as TV, VCR, DVD, CD, MD, etc. • CATV set top boxes • Multi-media Equipment • Other devices using IR remote control 1 Copyright © 2010, Everlight All Rights Reserved.

Issue No: DMO-0000206 Rev.3 See chapter ‚Test method’ ISINK ≦2mA www.everlight.com DATASHEET Infrared Receiver Module IRM-37xxM3 series Test method The specified electro-optical characteristics are valid under the following conditions. 1. Measurement environment A place without extreme light reflections. 2. External light The environment contains an ordinary, white fluorescent lamp without high frequency modulation. The color temperature is 2856K and the illumination at the IR receiver is less than 10 Lux (Ev 10Lux). 3. Standard transmitter The test transmitter is calibrated by using the circuit shown in figure 2. The radiation intensity of the transmitter is adjusted until Vo=400mVp-p. Both, the test transmitter and the photo diode, have a peak wavelength of 940nm. The photo diode for calibration is PD438B (λp=940nm, Vr=5V). ≦ 4.
