Infrared Transceiver
9.6 kbit/s to 115.2 kbit/s (SIR)
Description
The TFBS4650 is one of the smallest IrDA^® compliant
transceivers available. It supports data rates up to
115 kbit/s. The transceiver consists of a PIN photo-
diode, infrared emitter, and control IC in a single pack-
age.
Features
• Compliant with the IrDA physical layer
IrPHY 1.4 (low power specification,
9.6 kbit/s to 115.2 kbit/s)
• Link distance: 30 cm/20 cm full 15° cone
e4
with standard or low power IrDA, respec-
tively. Emission intensity can be set by an external
resistor to increase the range for extended low
power spec to > 50 cm
• Typical transmission distance to standard device:
50 cm
• Small package -
L 6.8 mm x W 2.8 mm x H 1.6 mm
• Low current consumption
75 µA idle at 3.6 V
20206
• Shutdown current 10 nA typical at 25 °C
• Operates from 2.4 V to 3.6 V within specification
over full temperature range from - 25 °C to + 85 °C
• Split power supply, emitter can be driven by a sep-
arate power supply not loading the regulated. U.S.
