Appendix B
Application Guideline
In the following some guideline is given for handling
the TFDU6108 in an application ambient, especially
for testing. It is also a guideline for interfacing with a
controller. We recommend to use for first evaluation
the Vishay IRM1802 controller. For more information
see the special data sheet. Driver software is avail-
able on request. Contact irdc@vishay.com.
Serial Interface Capability of the Vishay
IrDA Transceivers Abstract
A serial interface allows an infrared controller to com-
municate with one or more infrared transceivers. The
basic specification of IrDA
specified interface is
described in "Serial Interface for Transceiver Control,
v 1.0a", IrDA.
This part of the document describes the capabilities of
the serial interface implemented in the Vishay IrDA
transceivers TFDU8108 and TFDU6108. The VFIR
(16 Mbit/s) and FIR (4 Mbit/s) programmable versions
are using the same interface specification (with spe-
cific identification and programming).
IrDA Serial Interface Basics
The

erial
i
nterface for
t
ransceiver
c
ontrol (SITC) is a
master/slave synchronous serial bus which uses the
Txd and Rxd as data lines and the SCLK as clock line
with a minimum period of 250 ns. The transceiver
works always as slave and jump into SITC mode on
the first rising edge of the clock line remaining there
until the command phase is finished. After power on it
is required an initial phase for
≥
30 clock cycles at Txd
is continuous low before the transmitter can be pro-
grammed. If Txd assume high during the initial phase
then must start the initial phase again.
The data transfer is organized by one byte preceded
by one start bit. The SITC allows the communication
between infrared controller and transceiver through
write and read transaction. The SITC consists of two
store blocks with different functions. The store block
called Extended Indexed Registers contain the vari-
ous supported functionality of the device and can be
read only. The other Main Control Registers allow
write and read transaction and store the executable
configuration of the device.
Any configuration is executed after the command
phase is completed.
Power - up defaults
After power on the transceiver has to stay by definition in the following default mode shown in the table. The default mode of the TFDU6108
is different from the originally defined IrDA Serial Interface default mode. The implemented deviation from the standard was a market re-
quest because only in this way a requested quick function test is possible with the TFDU6108 without the need to connect to a programming
device.
