Vishay Semiconductors
Infrared Transceiver, 9.6 kbit/s to 115.2 kbit/s (SIR)
20206
DESCRIPTION
The TFBS4652 is one of the smallest IrDA^® compliant
transceivers available. It supports data rates up to 115 kbit/s.
The transceiver consists of a PIN photodiode, infrared
emitter, and control IC in a single package.
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 with
standard or low power IrDA, respectively.
Emission intensity can be set by an external
resistor to increase the range to > 50 cm
• Typical transmission distance to standard device: 50 cm
• Small package (L x W x H in mm): 6.8 x 2.8 x 1.6
• Low current consumption 75 µA idle at 3.6 V
• 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 separate
power supply not loading the regulated.
U.S. pat. no. 6,157,476
• Adjustable to logic I/O voltage swing from 1.5 V to 5.5 V
• Qualified for lead (Pb)-free and Sn/Pb processing (MSL4)
• Compliant to RoHS directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
• Mobile phone
• PDAs
