Description
TSIL6400 is a high efficiency infrared emitting diode in GaAlAs on GaAs technology, molded in clear, bluegrey tinted plastic packages.
In comparison with the standard GaAs on GaAs technology these emitters achieve about 70 % radiant power improvement at a similar wavelength.
The forward voltages at low current and at high pulse current roughly correspond to the low values of the standard technology. Therefore these emitters are ideally suitable as high performance replacements of standard emitters.

Features
*Extra high radiant power and radiant intensity
*Low forward voltage
*Suitable for high pulse current operation
*Standard T–1 (ø 5 mm) package
*Angle of half intensity j = ± 17
*Peak wavelength p = 925 nm
*High reliability
*Good spectral matching to Si photodetectors

Applications
*Infrared remote control units with high power requirements
*Free air transmission systems
*Infrared source for optical counters and card readers
*IR source for smoke detectors

Description
The IC U2532B is a complete IR-Transmitter-Receiver IC according to the new IrDA 1.0 standard. ASK-modulation is also possible. Only an external PIN-photodiode and an infrared emitting diode with current limiting resistor must be connected to the corresponding pins. The amplifier with Schmitt-Trigger formed output signal and the IR-driver need no further external components. The IC allows data rates from 2.4 kbit/s to 115.2 kbit/s and up to 500 kHz for
ASK-modulation. Two different sensitivity modes, which can be programmed by applying a “High” or “Low” voltage at pin SC, ensure either an increase in transmission distance or a bit error rate of 1E-9. An internal AGC allows proper operation under EMI conditions.

Features
*Data rates up to 115.2 kbit/s
*Wide supply voltage range (3 to 5.5 V)
*AGC for EMI immunity
*AGC reset
*High and low sensitivity mode
*BER < 1E-9 in the low sensitivity mode
*Power-On reset

Applications
*IR data transmission
*Compatible to IrDA
*Bidirectional IR data transmission
*Ability to receive ASK modulation
