TFDU5107
Vishay Semiconductors
Integrated Low Profile Transceiver Module
for Telecom Applications
9.6 kbit/s to 1.152 Mbit/s Data Transmission Rate
Description
The miniaturized TFDU5107 in the well-known Baby
Face package is an ideal transceiver for applications
in telecommunications like mobile phones, pagers,
and PDAs of all kinds. The devices are designed for
optimum performance and minimum package size.
The device covers the IrDA^® physical layer
specification with SIR specification and 1.152 Mbit/s
IrDA^® mode.
The new features
A current limiter is implemented to operate the device
whitout external resistor in an IrDA compliant mode
(> 1 m). For reduced current as for the “Low Power”
mode a current limiting resistor might be added.
The device covers the supply voltage from 3.6 V
down to 2.4 V and with its low power consumption
it is optimum suited for battery powered applications.
Double eye safety protection by pulse duration and
current limitation is integrated.
As additional feature the logic voltage swing V_logic
can be set externally.
