description

TheTSLM1100isaninfraredtransceiverthatprovidestheinterfacebetweenlogicandIRsignalsforthrough-air,

serial, half-duplex IR data links. The TSLM1100 is compliant with the Infrared Data Association (IrDA) 1.1

physical-layer specification. Additionally, the TSLM1100 is compatible with ASK, HP-SIR and TV Remote

standards.

The TSLM1100 is a hybrid device that includes a high-speed AIGaAs 870-nm LED, a silicon intrinsic PN junction

(PIN) diode, and a LinCMOS transceiver integrated circuit. This IC has the LED driver and a receiver that

provides two output signals: RXD-A for data rates from 2.4 kb/s to 115.2 kb/s and RXD-B for data rates of

576 kb/s to 4.0 Mb/s.

The device is encapsulated in a visible-light-rejecting plastic package that has integral lenses for the LED and

the PIN diode. The receiver lens increases the effective area of the PIN diode to increase sensitivity. The LED

lens is designed to provide a beam angle of ± 30°. The receiver outputs pulse low when an IR signal is detected.

The power supply for both PIN diode and LED should be filtered to minimize noise from external sources.

This transceiver is well suited for a wide variety of IR interface applications including: PC notebooks, PDAs,

pagers, printers, cameras, LANs, telephones and industrial handheld devices.
