HSDL-1100

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 specification. Errorless 4 Mb/s performance at link distances of 1.3-1.95 meters has been verified using the HSDL-1100 and I/O chips such as the National Semiconductor PC87108, the VLSI VL82C147, and the SMC FDC37C957. Nose-to-Nose (0-5 cm) errorless performance has also been verified for an Ir link using the HSDL-1100 and I/O chips. Sharp ASK/DASK errorless performance on the Rxd-B channel has been verified at 38.4 kb/s using the National Semiconductor PC87108. Link distance exceeded 2 meters for typical HSDL-1100 units. As with the HSDL-1000, the one-piece package of the HSDL-1100 allows the Ir system designer to easily meet all IrDA viewing angle specifications. Switching between IrDA data rates is effortless as data is always present at one of two receiver outputs RxdA and RxdB. Rxd-A provides 2.4115.2 kb/s data, and Rxd-B provides 0.5-4 Mb/s data. Capable of Receiving and Transmitting Sharp ASK/DASK and TV Remote VCC CX7 The Rxd-B receiver channel has been verified to correctly receive Sharp ASK/DASK 500 kHz carrier for data rates of 9.6 kb/s, 19.2 kb/s, and 38.4 kb/s.
