NTE31000

NTE31000 IR Receiver Module for Remote Control Systems Description: The NTE31000 is a miniaturized receiver for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame, the epoxy package acts as an IR filter. The demodulated output signal can be directly decoded by a microprocessor. The NTE31000 is compatible with all common IR remote control data formats, primarily older AGC2 designs. This component has not been qualified according to automotive specifications.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect the devices reliability. Electrical and Optical Characteristics: (TA = 25°C unless otherwise specified) Parameter Symbol Supply Current Supply Voltage Test Conditions ISD EV = 0, VS = 3.3V ISH EV = 40klx, sunlight Min d Max Unit 0.27 0.35 0.45 mA − 0.45 − mA 2.5 − 5.5 V EV = 0, IF = 250mA − 45 − m IOSL = 0.5mA, Ee = 0.7mW/m2 − − 100 mV VS Transmission Distance Typ Output Voltage Low VOSL Minimum Irradiance Ee min.

Pulse Width Tolerance: tpi − 5/fo < tpo < tpi + 6/fo Suitable Data Format: The NTE31000 is designed to suppress spurious output pulses due to noise or disturbance signals. Data and disturbance signals can be distinguished by the devices according to carrier frequency, burst length and envelope duty cycle. The data signal should be close to the band−pass center frequency (e.g. 38kHz) and fulfill the conditions in the table below. When a data signal is applied to the IR receiver in the presence of a disturbance signal, the sensitivity of the receiver is reduced to insure that no spurious pulses are present at the output. Some examples of disturbance signals which are suppressed are: D DC light (e.g. from tungsten bulb or sunlight) D Continuous signals at any frequency D Strongly or weakly modulated noise from fluorescent lamps with electronic ballasts Minimum burst length 10 cycles/burst After each burst of length a minimum gap time is required 10 to 70 cycles ³ 10 cycles For bursts greater than a minimum gap time in the data stream is needed of 70 cycles > 4 x burst length Maximum number of continuous short burst/second 1800 Recommended for NEC code Yes Recommended for RC5/RC6 code Yes Recommended for Sony code Yes Recommended for Thomson 56kHz code Yes Recommended for Mitsubishi code (38kHz, preburst 8ms, 16 bit) Yes Recommended for Sharp code Yes Suppression of interference from fluorescent lamps Most common disturbance signals are suppressed .197 (5.0) .189 (4.8) .157 (4.0) .110 (2.8) .110 (2.8) R .274 (6.95) .325 (8.25) .219 (5.55) 1.181 (30.0) Min OUT VS GND .100 (2.45) .100 (2.45) .047 (1.2)
