www.DataSheet4U.com TFDU5307 Vishay Semiconductors Fast Low Profile (2.5 mm) Infrared Transceiver Module (MIR, 1.152 Mbit/s) for IrDA® Applications Description The TFDU5307 is an infrared transceiver module compliant to the latest IrDA physical layer standard, supporting IrDA speeds up to 1.152 Mbit/s (MIR) and carrier based remote control modes up to 2 MHz. Integrated within the transceiver module are 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 Vishay MIR transceiver is built in a low profile package using the experiences of the lead frame babyface technology. The transceivers are capable of directly interfacing with a wide variety of I/O devices, which perform the modulation/ demodulation function. At a minimum, a VCC bypass capacitor and a serial resistor for current control are the only external components required implementing a complete solution. TFDU5307 has a tri-state output and is floating in shutdown mode with a weak pull-up. Features • Compliant to the latest IrDA physical layer specification (up to 1.152 Mbit/s) and TV Remote Control, bi-directional e3 operation included. • Sensitivity covers full IrDA range.

A separate unregulated power supply can be used at this pin. IRED Cathode, internally connected to the driver transistor This Schmitt-Trigger input is used to transmit serial data when SD is low. An onchip protection circuit disables the LED driver if the TXD pin is asserted for longer than 80 μs. When used in conjunction with the SD pin, this pin is also used to control receiver output pulse duration. The input threshold voltage adapts to and follows the logic voltage reference applied to the Vlogic pin (pin 7). Received Data Output, push-pull CMOS driver output capable of driving standard CMOS or TTL loads. No external pull-up or pull-down resistor is required. Floating with a weak pull-up of 500 kΩ (typ.) in shutdown mode. The voltage swing is defined by the applied Vlogic voltage Shutdown. Also used for setting the output pulse duration. Setting this pin active for more than 1.5 ms places the module into shutdown mode. Before that (t < 0.7 ms) on the falling edge of this signal, the state of the TXD pin is sampled and used to set the receiver output to long pulse duration (2 µs) or to short pulse duration (0.4 μs) mode. The input threshold voltage adapts to and follows the logic voltage reference applied to the Vlogic pin (pin 7). Supply Voltage Vlogic defi.
