TFBS4711 Vishay Semiconductors Serial Infrared Transceiver SIR, 115.2 kbit/s, 2.4 V to 5.5 V Operation FEATURES • Compliant with the latest IrDA physical layer low power specification (9.6 kbit/s to 115.2 kbit/s) • Small package (H x L x W in mm): 1.9 x 3 x 6 • Typical link distance on-axis up to 1 m • Battery and power management features: > Idle current - 70 µA typical > Shutdown current - 10 nA typical > Operates from 2.4 V to 5.5 V within specification over full temperature range from - 25 °C to + 85 °C 20208 DESCRIPTION The TFBS4711 is a low profile, infrared data transceiver module. It supports IrDA® data rates up to 115.2 kbit/s (SIR). The transceiver module consists of a PIN photodiode, an infrared emitter (IRED), and a low-power CMOS control IC to provide a total front-end solution in a single package. The device is designed for the low power IrDA standard with an extended range on-axis up to 1 m. The RXD output pulse width is independent of the optical input pulse width and stays always at a fixed pulse width thus making the device optimum for standard endecs. TFBS4711 has a tri-state output and is floating in shut-down mode with a weak pull-up. The shut down (SD) feature cuts current consumption to typically 10 nA.

(3) IrDA sensitivity definition: minimum irradiance E in angular range, power per unit area. The receiver must meet the BER specification while e 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 E in angular range, power per unit area. 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 ralated link errors. If placed at the active output interface reference plane of the transmitter, the receiver must meet its bit error ratio (BER). For more definitions see the document “Symbols and Terminology” on the Vishay website. (5) Using an external current limiting resistor is allowed and recommended to reduce IRED intensity and operating current when current reduction is intended to operate at the IrDA low power conditions. E.g. for VCC2 = 3.3 V a current limiting resistor of RS = 56 will allow a power minimized operation at IrDA low power conditions. (6) 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. Phillips RC5/RC6® or RECS 80.

The capacitor C2 combined with the resistor R2 is the low pass filter for smoothing the supply voltage. R2, C1 and C2 are optional and dependent on the quality of the supply voltages VCC1 and injected noise. An unstable power supply with dropping voltage during transmision may reduce the sensitivity (and transmission range) of the transceiver. The placement of these parts is critical. It is strongly recommended to position C2 as close as possible to the transceiver pins. When extended wiring is used as in bench tests the inductance of the power supply can cause dynamically a voltage drop at VCC2. Often some power supplies are not able to follow the fast current rise time. In that case another 4.7 µF (type, see table under C1) at VCC2 will be helpful. Under extreme EMI conditions as placing an RF-transmitter antenna on top of the transceiver, we recommend to protect all inputs by a low-pass filter, as a minimum a 12 pF capacitor, especially at the RXD port. The transceiver itself withstands EMI at GSM frequencies above 500 V/m. When interference is observed, the wiring to the inputs picks it up. It is verified by DPI measurements that as long as the interfering RF - voltage is below the logic threshold levels of the inputs and equivalent levels at the outputs no interferences are expected. One should keep in mind that basic RF - design rules for circuits 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, Winfield Hill, 1989, Cambridge University Press, ISBN: 0521370957. The capacitor C1 is buffering the supply voltage and eliminates the inductance of the power supply line. This one should be a Tantalum or other fast capacitor to guarantee the fast rise time of the IRED current. The resistor R1 is the current limiting resistor, which may be used to reduce the operating current to levels below the specified controlled values for saving battery power. Vishay’s 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 shutdown input must be grounded for normal operation, also when the shutdown function is not used. www.vishay.com 6 Document Number: 82633 For technical questions within your region, please contact one of the following: Rev. 3.0, 19-Nov-10 [email protected], [email protected], [email protected] TFBS4711 Serial Infrared Transceiver SIR, 115.2 kbit/s, 2.4 V to 5.5 V Operation Vishay Semiconductors Vbatt 3 V to 3.6 V VS = 3.3 V Vdd IRED Anode IRTX TXD IRRX RXD IR MODE SD VCC1 R2 C2 GND 19296-2 Fig. 4 - Typical Application Circuit I/O AND SOFTWARE In the description, already different I/Os are mentioned.
