Infrared controller, transceiver
Two new TI devices provide the first fully compliant high-speed IrDA solution available. The TIR2000 infrared controller and TSLM1100 transceiver support IrDA 1.0 and 1.1, the main standards for infrared data communications, up to 4 Mbps. The controller also supports amplitude shift keying (ASK) and TV infrared standards. Suitable applications include PC and notebook computers, printers, personal digital assistants (PDAs) and telephones.
The TIR2000 controller serves as an interface between the ISA bus and the transceiver. It encodes and decodes information for conformance to the appropriate IR standard. It also converts data into a format that can be transmitted by the infrared transceiver. A selectable 16/64-byte FIFO helps increase system interrupt and DMA efficiency. Power management function and 5-V or 3.3-V operation provide low power consumption in battery-operated systems.
 The TSLM1100 transceiver includes a pin photodiode, a two-path receiver with LED driver and an 870-nm LED. CMOS process enables a high level of integration for improved reliability. The transceiver interfaces directly with an IrDA controller and operates at data rates from 2400 bps to 4 Mbps.
