... General Application Guide for the HSDL-1100 4 Mb/s Infrared Transceiver Application Note 1112 HSDL-1100 Performance Capability Designed to Meet the IrDA Physical Layer Specification version 1.1 • Performance is guaranteed at the 1.152 Mb/s and 4.0 Mb/s data rates. The HSDL-1100 is also backward compatible to 2.4-115.2 kb/s data rates as required by the IrDA specifica- tion. • ...

... TV Remote signals correctly. However, the sensitivity will allow only 2-3 meters of transmit to receive distance unless the transmit power of the remote signal is >100 mW/sr. • The HSDL-1100 transmitter is capable of correct Sharp ASK/ DASK and TV Remote data transmission at IrDA levels for transmitted intensity (mW/sr). HSDL-1100 Functional Description ...

... HSDL-1100 units, and either the National Semiconductor PC87108 I/O chip, the VLSI VL82C147 I/O chip, or the SMC FDC37C957 I/O chip. In reference to the HSDL-1100 diagram on page 1 of this note, the TXD, RXD-A, and RXD-B nodes can be connected directly to the chosen I/O chip. National Semiconductor ...

... SMC I/O chip IRTX pin could be left in a logic high state for an indeterminate period of time. Connection of the IRTX directly to R1/CX2 would damage the HSDL-1100’s LED if the IRTX line was left in the logic high state.
