TSLM1100 IrDA COMPLIANT TRANSCEIVER SOES034A – SEPTEMBER 1997 – REVISED OCTOBER 1997 D D D D D Fully Compliant with IrDA 1.1 (4 MBPS) Compatible with ASK, HP-SIR and TV Remote No Programming Required to Switch Speeds Backward Compatible to Slower IrDA Speeds Excellent Noise Immunity Fully Supportable by all Interface Chips Designed to Compensate for Light Loss Caused by Cosmetic Windows SRA PACKAGE (TOP VIEW) CX1 1 10 2 3 4 5 6 7 8 LEDA 9 GNDA CX4 VCC RXD-B GND TXD RXD-A CX3 D D description The TSLM1100 is an infrared transceiver that provides the interface between logic and IR signals for through-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.
