Noise resistance
It is believed that the use of optical transfer devices improve noise resistance. In theory, optical fiber
is not affected by noise at all. However, receiving modules which handle signals whose level is
extremely small, are susceptible to noise.
TOSLINK improve noise resistance to use a conductive case. However, the current signal output by
the optical receiving modules' photodiode is extremely small. Thus, in some environments, shielding
the case may not achieve sufficient noise resistance.
First systems which incorporate TOSLINK, Toshiba recommend testing using the actual device to
check its noise resistance.
Use a simple noise filter on TOSLINK fiber optic transceiving module's power line. If the ripple in the
power supply used is significant, reinforce the filter.
The optical module is to be used in an area which is susceptible to radiated noise, increase the
shielding by covering the optical module and the power line filter with a metallic cover.
Vibration and shock
This module is plastic sealed and has its wire fixed by resin. This structure is relatively resistant to
vibration and shock. In actual equipment, there are sometime cases in which vibration, shock, or
stress is applied to soldered parts or connected parts, resulting in lines cut. A care must be taken in
the design of equipment which will be subject to high levels of vibration.
Support pins
The TORX
1
79P has support pins in order to fix itself to the PCB temporary. Please make the hole for
these pins in the PCB under the condition described in board layout hole pattern.
Attaching the fiber optic receiving module
Solder the fixed pins (pins 4 and 5) of the fiber optic receiving module TORX
1
79P to the printed
circuit board in order to fix it to the board.
Solvent
When using solvent for flux removal, do not use a high acid or high alkali solvent. Be careful not to
pour solvent in to the optical connector ports. If solvent is inadvertently poured in to them, clean it off
using cotton tips.
Protective cap
When the TORX
1
79P is not in use, attach the protective cap.
Supply voltage
Use the supply voltage within the recommended operating condition (V
CC
= 5 ± 0.25 V). Make sure
that supply voltage does not exceed the maximum rating value of 7 V, even for an instant.

0) Output
If the receiver output is at low and is connected to the power supply, or if the output is high and is
connected to GND, the internal IC may be destroyed.

) Soldering condition
Solder at 260°C or less for no more than ten seconds.

3) Precautions during use
Toshiba is continually working to improve the quality and the reliability of their products.
Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical
sensitivity and their vulnerability to physical stress. It is the responsibility of the buyer, when
utilizing Toshiba products, to observe standards of safety, and to avoid situations in which the
malfunction or failure of a Toshiba product could cause loss of human life, bodily injury or damage to
property.
When developing equipment, please ensure that Toshiba products are used within the specified
operating ranges set forth in the most recent product specifications. Also, please keep in mind the
precautions and conditions set forth in the Toshiba Semiconductor Reliability Handbook.
