A separate unregulated power supply can be used. I/O ACTIVE 2 RXD Receiver output. Normally high, goes low for a defined pulse duration with the rising edge of the optical input signal. Output is a CMOS tri-state driver, which swings between ground and Vlogic. Receiver echoes transmitter output. O Low 3 TXD Transmitter data input. Setting this input above the threshold turns on the transmitter. This input switches the IRED with the maximum transmit pulse width of about 100 s. I High 4 SD Shutdown. Logic low at this input enables the receiver, enables the transmitter, and un-tri-states the receiver output. It must be driven high for shutting down the transceiver. I High 5 Vlogic Reference for the logic swing of the output and the input logic levels. I 6 VCC Power supply, 2.4 V to 3.6 V. This pin provides power for the receiver and transmitter drive section.

The optical delivered to the detector by a source operating at the maximum e intensity in angular range at minimum link length must not cause receiver overdrive distortion and possible related link errors.

It is strongly recommended to position C2 as close as possible to the transceiver power supply pins. When connecting the described circuit to the power supply, low impedance wiring should be used. In case of extended wiring the inductance of the power supply can cause dynamically a voltage drop at VCC2. Often some power supplies are not apply to follow the fast current is rise time. In that case another 10 F cap at VCC2 will be helpful. Keep in mind that basic RF-design rules for circuit design should be taken into account. Especially longer signal lines should not be used without termination. See e.g. "The Art of Electronics" Paul Horowitz, Wienfield Hill, 1989, Cambridge University Press, ISBN: 0521370957. RECOMMENDED APPLICATION CIRCUIT COMPONENTS COMPONENT RECOMMENDED VALUE C1, C2 0.1 F, ceramic Vishay part# VJ 1206 Y 104 J XXMT Fig. 1 - Recommended Application Circuit The capacitor C1 is buffering the supply voltage VCC2 and eliminates the inductance of the power supply line. This one should be a small ceramic version or other fast capacitor to guarantee the fast rise time of the IRED current. The resistor R1 is necessary for controlling the IRED drive current when the internally controlled current is too high for the application. Vishay 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) and the output RXD should be directly (DC) coupled to the I/O circuit.

For lead (Pb)-free solder paste like Sn(3.0 - 4.0)Ag(0.5 - 0.9)Cu, there are two standard reflow profiles: Ramp-Soak-Spike (RSS) and Ramp-To-Spike (RTS). The Ramp-Soak-Spike profile was developed primarily for reflow ovens heated by infrared radiation. With widespread use of forced convection reflow ovens the Ramp-To-Spike profile is used increasingly. Shown in figure 2 is Vishay's recommended profiles for use with the TFBS4652 transceivers. For more details please refer to the application note "SMD Assembly Instructions". Wave Soldering For TFDUxxxx and TFBSxxxx transceiver devices wave soldering is not recommended. Manual Soldering Manual soldering is the standard method for lab use. However, for a production process it cannot be recommended because the risk of damage is highly dependent on the experience of the operator. Nevertheless, we added a chapter to the above mentioned application note, describing manual soldering and desoldering. Storage The storage and drying processes for all Vishay transceivers (TFDUxxxx and TFBSxxx) are equivalent to MSL4. The data for the drying procedure is given on labels on the packing and also in the application note "Taping, Labeling, Storage and Packing".
