Infrared Transceiver Module (SIR, 115.2 kbit/s) for IrDA® Applications TFDU4301
●DESCRIPTION
■The TFDU4301 is a low profile (2.5 mm) infrared transceiver module. 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 solution 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.
■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 end ecs. TFDU4301has a tri-state output and is floating 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
■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 (< typ. supply current 70 μA)
■Power shutdown mode (< 1 μA shutdown current in full temperature range, up to 85 °C)
■Low profile (2.5 mm) (L x W x H in mm): 8.5 × 2.5 × 3.1
■Surface mount package
■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 or TOIM5232
■Tri-state-receiver output, floating in shut down with a weak pull-up
■Compliant with IrDA background light specification
