Fiber Optic Devices TOSLINK

TOTU133 and TORU133 Fiber Optic Transmission Units for Automotive

LAN Applications

Package Dimensions and Pin Connections

The fiber optic transmission units, the TOTU133 and

TORU133 are designed for automotive LAN

applications for information systems. These devices

draw on Toshiba's expertise in developing high-speed

TOSLINK solutions to achieve the high reliability and in

miniaturization and mass-production technologies.

The TOTU133 transmitter incorporates a high-speed

InGaP red LED and driver circuit, and the TORU133

receiver incorporates a photodiode and waveform-

reshaping circuit on a single chip. The interface is 3.3 V

PECL for both the TOTU133 and TORU133, facilitating

an easier connection with peripheral circuits.

Handling Precautions

●

The graphs above are only shown as an example and are not intended to guarantee the characteristics.

Lifetime Characteristics

In fiber optic transmission units that ha ve been in use for some time, nearly all of the deterioration in characteristics is due to

a reduction in the fiber-output power (Pf). This is due to deterioration o ver time in the level of optical output of the LED used

as the light source.

The drop in the LED's optical output is thought to be caused by crystal flaws in the wafer or stress in the mold resin,

although the detailed causes are not clear.

The lif e of light-emitting devices is greatly affected by the operating conditions and operating environment as w ell as by the

lif espan char acteristics of the particular device. Toshiba recommends that the user first check a device's lifetime

characteristics before selecting it and setting its oper ating conditions.

Regular maintenance, such as a chec k on the amount of light emitted is recommended.

Noise Resistance

To operate the fiber optic transmission units normally, they must be enclosed in a conductive case. The case for the units

is made of conductive material and should be grounded to provide shielding effectiveness. Also, the case potential must

be the same as for the SIGNAL-GND.

In some environments, simply shielding the case will not protect against noise. When using the fiber optic transmission

units, conduct live tests to check noise resistance.

Application Ranges

The fiber optic transmission units described in this product guide are intended for use in entertainment information

systems (e.g., car audio systems, navigation systems with no information that could affect the safety). These products

shall not be used in equipment whose malfunction or failure could have direct effects on the safety of the driver and/or

passengers.

Application Precautions

TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor devices

in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the

responsibility of the buyer, when utilizing TOSHIBA products, to comply with the standards of safety in making a safe

design for the entire system, and to avoid situations in which a malfunction or failure of such TOSHIBA products could

cause loss of human life, bodily injury or damage to property. In developing your designs, please ensure that TOSHIBA

products are used within specified operating ranges as set forth in the most recent TOSHIBA products specifications.

Also, please keep in mind the precautions and conditions set forth in the "Handling Guide for Semiconductor Devices," or

"TOSHIBA Semiconductor Reliability Handbook" etc..
