For SMC Super and Ultra I/O

Controller chips, IR link can be

realized with the following con-

nections:

• Connect IRTX of the SMC

Super or Ultra I/O Controller to

TXD (pin 9) of the HSDL-3602.

• Connect IRRX of the SMC

Super or Ultra I/O Controller to

RXD (pin 8) of the HSDL-3602.

• Connect IRMODE of the Super

or Ultra I/O Controller to

FIR_SEL (pin 3) of the

HSDL-3602.

Please refer to the table below for

the IR pin assignments for the SMC

Super or Ultra I/O Controllers that

support IrDA 1.1 up to 4Mb/s:

HSDL-3602 Interoperability with

SMC 669/769 Report

(i) Test Conditions

Vcc = 3.0 – 3.6 V

RLED = 2.2

Ω

Optical transmitter

pulse width = 125 ns

Mode set to full power

(ii) Test Result

The interoperability test results

show that HSDL-3602 IR

transceiver can operate

≥ 1.5

meter link distance from 3 V to

3.6 V with SMC 669/769 at any

IrDA 1.1 data rate without error.
