NJL21H/21V/22H/23H/24H000A
INFRARED REMOTE CONTROL RECEIVER
GENERAL DESCRIPTION
The NJL21H/21V/22H/23H/24H000A series are small and high performance receiving devices for infrared
remote control system. They can operate under low and wide supply voltage (2.7V to 5.5V) with enhanced
immunity against the disturbance light.
FEATURES
1. Wide and low supply voltage 2.7V to 5.5V
2. Low supply current
0.43mA typ. Vcc=3.3V
3. Mold type and metal case type to meet the design of front panel.
4. Line-up for various center carrier frequencies.
APPLICATIONS
1. AV instruments such as Audio, TV, VCR, CD, MD, DVD, STB etc.
2. Home application such as Air-conditioner, Fan etc.
3. Game machine, toy etc.

Note *1:Test with each center carrier frequency under the test condition shown below.
*2:Place major axis of elliptic lens in horizontal direction and minor vertical.
*3:Four types of frequency :36.0, 36.7, 38.0, 40.0KHz
TEST METHOD
Test condition is as follows:
(1) Standard transmitter:
Transmitting waveform is shown in Fig.1
Transmitting power should be adjusted
so that output voltage Vout will be
400mVp-p.(Test circuit is shown in Fig.2)
Regarding IR LED used for transmitter,
λp=940nm, ∆λ=50nm.
Regarding photo diode,
Sensitivity
S=26nA/Lx
in case light source temperature2856°K,
Ee=100Lx, VR=5V
Carrier frequency is adjusted to
center frequency of each product
