DATASHEET
Infrared Receiver Module
IRM-H6XXJ7/TR2(CLW) Series
Application considerations
IRM IR receiver modules are high gain analog components to reach a long reception range. However, due to the high
gain, they are also sensitive to noise from the power supply like V
cc
ripple. Noise on the power supply can reduce the
reception range of the IRM or cause output glitches and corrupted data. To protect the IRM receiver from power
supply noise, a RC filter must be connected as close as possible to the V
cc
and GND pins of the IRM. The circuit
below in figure 9 shows the configuration of the RC filter and the required values. Ceramic or tantalum capacitor
should be used, as standard electrolytic capacitors are only suitable for low frequencies and might not be able to filter
noise in the frequency range of the IRM. The IRM receiver is most sensitive to noise which is at the carrier frequency
or close to the carrier frequency. When using a switching mode power supply, the switching frequency must not be
the same as the carrier frequency of the IRM. A gap of at least 20kHz between the switching frequency of the power
supply and the IRM carrier frequency is recommended.
If the trace from the IRM output pin to the decoder IC on the PCB is long, the parasitic capacitance might be high
causing slow rise times of the IRM output signal. In such case, an additional pull up resistor of 10kOhm or higher can
be added at the IRM output to reduce the influence of parasitic trace capacitance.

Code compatibility
The IRM-H6xxJ7 receiver modules are mainly designed for remote control applications which require very high noise
immunity. Hence the IR code compatibility is matched for the most common IR protocols. To guarantee a proper data
signal reception, a few points need to be taken into consideration.
The signal transmission must be carried out in data packages with limited length followed by a data pause time of a
certain length. Continuous data transmission is not applicable as such kind of signal will be judged as noise and
suppressed after a short time. Table1 below shows the compatibility to most commonly used IR protocols. If an IR protocol
is not listed in this table, the compatibility needs to be checked according to the burst times, gap times, data package
length and data pause time. The required limits for these items are shown in table 2 “acceptable IR signal timings”.

Operation under noisy environment
The IRM-H6XXJ7 receiver modules have noise suppression functions implemented, such as band pass filter, AGC
amplifier and threshold control. But noise will cause decreased reception distance or in case of strong noise output glitches
can occur and might corrupt the data signal. This needs to be considered by the decoder.
The presence of noise also can affect the output pulse jitter. In such case, the output pulse jitter shown in the
electro-optical specification above, might not be valid anymore and bigger pulse jitter can occur. This behavior needs to be
considered when tuning the timing limits of the decoder. It is recommended to use the output pulse variation shown in the
electro-optical specifications above as a base to set the timing limits of the decoder. However, due to different protocols
and environmental conditions, other timing limits might result in better performance and decoding security. This needs to
be verified for the specific application by testing under different noise conditions.
