Infrared Transceiver, 9.6 kbit/s to 115.2 kbit/s (SIR)

DESIGN SUPPORT TOOLS AVAILABLE

DESCRIPTION

The TFBR4650 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 for extended low

power spec 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

• Shutdown current 10 nA typical at 25 °C

• Operates from 2.4 V to 5.5 V within specification over full

temperature range from -30 °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

• Qualified for lead (Pb)-free and Sn/Pb processing (MSL4)

• These components have not been qualified according to

automotive specifications

• Material categorization: for definitions of compliance
