| TFDU6100/TFDS6500/TFDT6500 Not for new designs Vishay Telefunken 5 V Fast Infrared Transceiver Module Family (FIR, 4 Mbit/s) Description The TFDU6100, TFDS6500, and TFDT6500 are a family of low-power infrared transceiver modules compliant to the IrDA 1.2 standard for fast infrared (FIR) data communication, supporting IrDA speeds up to 4.0 Mbit/s, HP-SIR, Sharp ASK and carrier based remote control modes up to 2 MHz. Integrated within the transceiver modules are a photo PIN diode, infrared emitter (IRED), and a low-power CMOS control IC to provide a total front-end solution in a single package. Vishay Telefunken's FIR transceivers are available in three package options, including our Baby Face package (TFDU6100), the smallest FIR transceiver available on the market. This wide selection provides flexibility for a variety of applications and space constraints. The transceivers are capable of directly interfacing with a wide variety of I/O chips which perform the modulation/ demodulation function, including National Semiconductor's PC87338, PC87108 and PC87109, SMC's FDC37C669, FDC37N769 and CAM35C44, and Hitachi's SH3. At a minimum, a current-limiting resistor in series with the infrared emitter and a VCC bypass capacitor are the only external components required to implement a complete solution.

The upper drive current limitation is dependent on the duty cycle and is given by the absolute maximum ratings on the data sheet. R2, C1 and C2 are optional and dependent on the quality of the supply voltage VCC and injected noise. An unstable power supply with dropping voltage during transmission may reduce sensitivity (and transmission range) of the transceiver. 500 5.25V 400 Intensity (mW/sr) 300 200 100 0 0 14379 Recommended Circuit Diagram The only required component for designing an IrDA 1.2 compatible design using Telefunken FIR transceivers is a current limiting resistor, R1, to the IRED. However, depending on the entire system design and board layout, additional components may be required (see figure 3).

Recommended Application Circuit "15 14 16 Telefunken FIR transceivers integrate a sensitive receiver and a built-in power driver. The combination of both needs a careful circuit board layout. The use of thin, long resistive and inductive wiring should be avoided. The inputs (Txd, SD/Mode) and the output Rxd should be directly (DC) coupled to the I/O circuit. R1 is used for controlling the current through the IR emitter. For increasing the output power of the IRED, the value of the resistor should be reduced. Similarly, to reduce the output power of the IRED, the value of the resistor should be increased. For typical values of R1 see figure 4. For IrDA compliant operation, a Current Control Resistor ( W ) Figure 4. Intesity Ie vs. Current Control Resistor R1 The placement of these parts is critical. It is strongly recommended to position C2 as near as possible to the transceiver power supply pins. A tantalum capacitor should be used for C1 while a ceramic capacitor is used for C2. Also, when connecting the described circuit to the power supply, low impedance wiring should be used. Table 1.

A3, 01-Apr-99 TFDU6100/TFDS6500/TFDT6500 Not for new designs Mode Switching The TFDU6100, TFDS6500 and TFDT6500 powers on with a default of low frequency mode. The low frequency mode covers speeds up to 115.2 kbit/s. Signals with higher data rates should be detected in the high frequency mode. Lower frequency data can also be received in the high frequency mode but with reduced sensitivity. To switch the transceivers from low frequency mode to the 4.0 Mbit/s mode and vice versa, the programming sequences described below are required. Vishay Telefunken Setting to the High Bandwidth Mode (0.576 Mbit/s to 4.0 Mbit/s) 1. Set SD/MODE input to logic "HIGH". 2. Set Txd input to logic "HIGH". Wait ts 200 ns. 3. Set SD/MODE to logic "LOW" (this negative edge latches state of Txd, which determines speed setting). 4. After waiting th 200 ns Txd can be set to logic "LOW". The hold time of Txd is limited by the maximum allowed pulse length. Txd is now enabled as normal Txd input for the high bandwidth mode. SD/Mode 50% Setting to the Lower Bandwidth Mode (2.4 kbit/s to 115.2 kbit/s) ts Txd 50% th High : FIR 50% Low : SIR 1. Set SD/MODE input to logic "HIGH". 2. Set Txd input to logic "LOW". Wait ts 200 ns. 3. Set SD/MODE to logic "LOW" (this negative edge latches state of Txd, which determines speed setting). 4. Txd must be held for th 200 ns. 14873 Figure 5.

Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances ( ODSs ). The Montreal Protocol ( 1987 ) and its London Amendments ( 1990 ) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency ( EPA ) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively. Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. Vishay Telefunken We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use Vishay Telefunken products for any unintended or unauthorized application, the buyer shall indemnify Vishay Telefunken against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
