Transceiver

Application Note 1112

HSDL-1100 Performance

Capability

Designed to Meet the IrDA Physical

Layer Specification version 1.1

• Performance is guaranteed at

• Errorless 4 Mb/s performance

• Nose-to-Nose (0-5 cm) error-

• Sharp ASK/DASK errorless

• As with the HSDL-1000, the

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.

at link distances of 1.3-1.95

meters has been verified using

the HSDL-1100 and I/O chips

such as the National Semicon-

ductor PC87108, the VLSI

VL82C147, and the SMC

FDC37C957.

less performance has also been

verified for an Ir link using the

HSDL-1100 and I/O chips.

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.

one-piece package of the

HSDL-1100 allows the Ir

system designer to easily meet

all IrDA viewing angle

specifications.

always present at one of two

receiver outputs RxdA and

RxdB. Rxd-A provides 2.4-

115.2 kb/s data, and Rxd-B

provides 0.5-4 Mb/s data.
