IRM-2638VS8F5-P
Descriptions
‧The IRM-2638VS8F5-P are miniaturized receivers for infrared
remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. IRM-2638VS8F5-P is the standard IR remote control receiver series, supporting all major transmission codes.
Applications
1. Optical switch 2. Light detecting portion of remote control ․AV instruments such as Audio, TV, VCR, CD, MD, etc. ․Home appliances such as Air-conditioner, Fan , etc. ․The other equipments with wireless remote control. ․CATV set top boxes ․Multi-media Equipment

IRM-2638VS8F5-P
The Notice of Application:
Transmission o remote control signal consist of four parts: Encode Part, IR Transmitter Source, IRM device, Decode Part
1. When IRM-2638VS8F5-P code select frequency, it need to well understand the center system of encode part.
2. Strong or weak light of IR Transmitter can affect distance of transmission. 3. Minimum Burst Length Tburst (number of pulses per burst) : 10 cycles 4. It needs to ensure the translation range of decode part if it is applied to the pulse-width range.
If the above items hardly assure of its application, it’ll cause NG(no good) message from the edge of signal.
Test Method:
The specified electro-optical characteristics is satisfied under the following Conditions at the controllable distance. cMeasurement place
A place that is nothing of extreme light reflected in the room. dExternal light
Project the light of ordinary white fluorescent lamps which are not high Frequency lamps and must be less then 10 Lux at the module surface. (Ee≦10Lux) eStandard transmitter A transmitter whose output is so adjusted as to Vo=400mVp-p and the output Wave form shown in Fig.-1.According to the measurement method shown in Fig.-2 the standard transmitter is specified. However , the infrared photodiode to be used for the transmitter should be λp=940nm,∆λ=50nm. Also, photodiode is used of PD438B(Vr=5V). fMeasuring system According to the measuring system shown in Fig.-3
