Precautions on Use (1) (2) (3) (4) (5) Absolute maximum rating The absolute maximum ratings are the limit values which must not be exceeded during operation of device. None of these rating value must not be exceeded. If the absolute maximum rating value is exceeded, the characteristics of devices may never be restored properly. In extreme cases, the device may be permanently damages. Soldering Optical modules are comprised of internal semiconductor devices. However, in principle, optical modules are optical components. During soldering, ensure that flux does not contact with the emitting surface or the detecting surface. Also ensure that proper flux removal is conducted after soldering. Some optical modules come with a protective cap. The protective cap is used to avoid malfunction when the optical module is not in use. Note that it is not dust or waterproof. As mentioned before, optical modules are optical components. Thus, in principle, soldering where there may be flux residue and flux removal after soldering is not recommended. Toshiba recommend that soldering be performed without the optical module mounted on the board. Then, after the board has been cleaned, the optical module should be soldered on to the board manually. If the optical module cannot be soldered manually, use non-halogen (chlorine-free) flux and make sure, without cleaning, there is no residue such as chlorine. This is one of the ways to eliminate the effects of flux. In such a cases, be sure to check the devices' reliability. 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. For 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 TORX147(F,T) 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. 3 2006-12-28 TORX147(F,T) (6) (7) (8) (9) (10) (11) (12) (13) Panel attachment TORX147(F,T) has hole for panel attachment. Please be sure to attach it to panel with self-tapping screw. 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 TORX147(F,T) is not in use, attach the protective cap. Supply voltage Use the supply voltage within the recommended operating condition (VCC = 2.7 to 3.6V). Make sure that supply voltage does not exceed the maximum rating value of 4.5 V, even for an instant. 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 260C or less for no more than ten seconds. Precautions when disposing of devices and packing materials. When disposing devices and packing materials, follow the procedures stipulated by local regulations in order to protect the environment against contamination. 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.
