5 / 13 page TFDU6103 Fast Infrared Transceiver Module (FIR, 4 Mbit/s) for 2.4 V to 5.5 V Operation Vishay Semiconductors Document Number: 81211 For technical questions within your region, please contact one of the following: irdasupportAM@vishay.com, irdasupportAP@vishay.com, irdasupportEU@vishay.com www.vishay.com Rev. 1.4, 29-Jul-09 5 Notes (1) Tamb = 25 °C, VCC = 2.4 V to 5.5 V unless otherwise noted. All timing data measured with 4 Mbit/s are measured using the IrDA FIR transmission header. The data given here are valid 5 µs after starting the preamble. Typical values are for design aid only, not guaranteed nor subject to production testing. (2) This parameter reflects the backlight test of the IrDA physical layer specification to guarantee immunity against light from fluorescent lamps. (3) IrDA sensitivity definition: minimum irradiance Ee in angular range, power per unit area. The receiver must meet the BER specification while the source is operating at the minimum intensity in angular range into the minimum half-angular range at the maximum link length. (4) Maximum irradiance Ee in angular range, power per unit area. The optical delivered to the detector by a source operating at the maximum intensity in angular range at minimum link length must not cause receiver overdrive distortion and possible related link errors. If placed at the active output interface reference plane of the transmitter, the receiver must meet its bit error ratio (BER) specification. For more definitions see the document “Symbols and Terminology” on the Vishay website (5) Retriggering once during applied optical pulse may occur. (6) Maximum value is given by eye safety class 1, IEC 60825-1, simplified method. (7) Due to this wavelength restriction compared to the IrDA spec of 850 nm to 900 nm the transmitter is able to operate as source for the standard remote control applications with codes as e.g. Philips RC5/RC6® or RECS 80. When operated under IrDA full range conditions (125 mW/sr) the RC range to be covered is in the range from 8 m to 12 m, provided that state of the art remote control receivers are used.
