333 3 TFDU4101 www.vishay.com Vishay Semiconductors Infrared Transceiver Module (SIR, 115.2 kbit/s) for IrDA Applications FEATURES Operates from 2.4 V to 5.5 V within specification over full temperature range from -30 C to +85 C Split power supply, transmitter and receiver 20110 can be operated from two power supplies with relaxed requirements saving costs, US - patent no. 6,157,476 Low power consumption (< 0.12 mA supply current in receive mode, no signal) LINKS TO ADDITIONAL RESOURCES Power shutdown mode (< 4 A shutdown current in full temperature range, up to 85 C, < 10 nA at 25 C) 3D Models Surface-mount package (L x W x H in mm): 9.7 4.7 4 High efficiency emitter DESCRIPTION Low profile (universal) package capable of surface moun t The TFDU4101 transceiver is an infrared transceiver module soldering to side and top view orientation compliant to the latest IrDA physical layer standard for fast Directly Interfaces with various super I/O and encoder / infrared data communication, supporting IrDA speeds up to decoder devices 115.2 kbit/s (SIR), and carrier based remote control modes. Tri-state-receiver output, floating in shut down with a Integrated within the transceiver module are a photo pin weak pull-up diode, an infrared emitter (IRED), and a low-power control IC Qualified for lead (Pb)-free and Sn/Pb processing (MSL4) to provide a total front-end solution in a single package. This device covers the full IrDA range of more than 1 m using the Material categorization: for definitions of compliance please see www.vishay.com/doc 99912 internal intensity control. With one external current control resistor the current can be adjusted for shorter ranges APPLICATIONS saving operating current operating in IrDA low power mode. This Vishay SIR transceiver is using the lead frame Printers, fax machines, photocopiers, screen projectors technology. Internet TV boxes, video conferencing systems The receiver output pulse duration is independent of the Medical data collection optical input pulse duration and recovers always a fixed Diagnostic systems pulse duration optimum for compatibility to standard Notebook computers, desktop PCs, palmtop computers Endecs and interfaces. TFDU4101 has a tristate output an d (Win CE, Palm PC), PDAs is floating in shutdown mode with a weak pull-up.

An external resistor is CC2 only necessary for controlling the IRED current when a current reduction V CC2 1 below 300 mA is intended to operate in IrDA low power mode. IRED anode This pin is allowed to be supplied from an uncontrolled power supply separated from the controlled V - supply. CC1 2 IRED cathode IRED cathode, internally connected to driver transistor This Schmitt-Trigger input is used to transmit serial data when SD is low. 3TXD An on-chip protection circuit disables the LED driver if the TXD pin is IHigh asserted for longer than 50 s (max. 300 s). Received data output, push-pull CMOS driver output capable of driving standard CMOS or TTL loads. During transmission the RXD output is 4RXD OLow active (echo-on). No external pull-up or pull-down resistor is required.
