1 / 15 page  VISHAY TFDU4300 Document Number 82614 Rev. 1.4, 26-Jan-04 Vishay Semiconductors www.vishay.com 1 18065 Infrared Transceiver Module (SIR, 115.2 kbit/s) for IrDA® applications Description The TFDU4300 is a low profile (2.5 mm) infrared transceiver module with independent logic reference voltage (Vlogic) for low voltage IO interfacing. It is compliant to the latest IrDA physical layer standard for fast infrared data communication, supporting IrDA speeds up to 115.2 kbit/s (SIR) and carrier based remote control. The transceiver module consists of a PIN photodiode, an infrared emitter (IRED), and a low-power control IC to provide a total front-end solu- tion in a single package. This device covers an extended IrDA low power range of close to 1 m. With an external current control resistor the current can be adjusted for shorter ranges. This Vishay SIR transceiver is built in a new smaller package using the experiences of the lead frame BabyFace technology. The Rxd output pulse width is independent of the opti- cal input pulse width and stays always at a fixed pulse width thus making the device optimum for standard Endecs. TFDU4300 has a tri-state output and is float- ing in shut-down mode with a weak pull-up. Features • Compliant to the latest IrDA physical layer specification (9.6 kbit/s to 115.2 kbit/s) and TV Remote Control, bi-directional operation included. • Operates from 2.4 V to 5.5 V within specification over full temperature range from - 30 °C to + 85 °C • Logic voltage 1.5 V to 5.5 V is independent of IRED driver and analog supply voltage • Split power supply, transmitter and receiver can be operated from two power supplies with relaxed requirements saving costs, US Patent No. 6,157,476 • Extended IrDA Low Power Range to about 70 cm • Typical Remote Control Range 12 m • Low Power Consumption (< 0.12 mA Supply Current) • Power Shutdown Mode (< 5 µA Shutdown Current in Full Temperature Range, up to 85 °C) • Surface Mount Package, low profile (2.5 mm) - (L 8.5 mm × H 2.5 mm × W 2.9 mm) • High Efficiency Emitter • Low Profile (Universal) Package Capable of Surface Mount Soldering to Side and Top View Orientation • Directly Interfaces with Various Super I/O and Controller Devices as e.g. TOIM4232 • Tri-state-Receiver Output, floating in shut down with a weak pull-up • Compliant with IrDA Background Light Specification • EMI Immunity in GSM Bands > 300 V/m verified Applications • Ideal for Battery Operated Applications • Telecommunication Products (Cellular Phones, Pagers) • Digital Still and Video Cameras • Printers, Fax Machines, Photocopiers, Screen • Projectors • Medical and Industrial Data Collection • Diagnostic Systems • Notebook Computers, Desktop PCs, Palmtop Computers (Win CE, Palm PC), PDAs • Internet TV Boxes, Video Conferencing Systems • External Infrared Adapters (Dongles) • Data Loggers • GPS • Kiosks, POS, Point and Pay Devices including IrFM - Applications |
