DESCRIPTION

The receiver component converts the optical serial data into

PECL compatible electrical data (RD and RDnot). The Signal

Detect (SD, active high) shows whether an optical signal is

present.

The Infineon Gigabit Ethernet multimode transceiver—part of

Infineon Small Form Factor transceiver family—is based on the

Physical Medium Depend (PMD) sublayer and baseband

medium, type 1000BASE-SX (short wavelength).

The transmitter converts PECL compatible electrical serial data

(TD and TDnot) into optical serial data. Data lines are differen-

tially 100 Ω terminated.

The appropriate fiber optic cable is 62.5 µm or 50 µm multi-

mode fiber with VF-45™ (Volition™) connector.

The transmitter contains a laser driver circuit that drives the

modulation and bias current of the laser diode. The currents are

controlled by a power control circuit to guarantee constant out-

put power of the laser over temperature and aging. The power

control uses the output of the monitor PIN diode (mechanically

built into the laser coupling unit) as a controlling signal, to pre-

vent the laser power from exceeding the operating limits.

Single fault condition is ensured by means of an integrated

automatic shutdown circuit that disables the laser when it

detects transmitter failures. A reset is only possible by turning

the power off, and then on again.

Not Supported

The Infineon Gigabit Ethernet multimode transceiver is a single

unit comprised of a transmitter, a receiver, and an VF-45™

receptacle. This design frees the customer from many align-

ment and PC board layout concerns.

The transceiver contains a supervisory circuit to control the

power supply. This circuit makes an internal reset signal when-

ever the supply voltage drops below the reset threshold. It

keeps the reset signal active for at least 140 milliseconds after

the voltage has risen above the reset threshold. During this

time the laser is inactive.

This transceiver supports the innovative Volition connectoriza-

tion concept, which competes with UTP/CAT 5 solutions. It is

compatible with RJ-45 style backpanels for fiber-to-the-desktop

applications while providing the advantages of fiber optic tech-

nology. The receptacle accepts the new SG/VF-45™ connector.

The Small Form Factor is specially developed for distances of

up to 550 m.

TECHNICAL DATA

The electro-optical characteristics described in the following

tables are valid only for use under the recommended operating

conditions.

The module is designed for low cost LAN, WAN, and Gigabit

Ethernet applications. It can be used as the network end

device interface in mainframes, workstations, servers, and

storage devices, and in a broad range of network devices such

as bridges, routers, hubs, and local and wide area switches.

1. Average optical power at which the BER is 1 x 10E–12. Measured

with a 2 –1 NRZ PRBS and ER=9 dB.

2. An increase in optical power above the specified level will cause the

SIGNAL DETECT output to switch from a Low state to a High state.

3. A decrease in optical power below the specified level will cause the

SIGNAL DETECT to change from a High state to a Low state.

4. PECL compatible. Load is 50 Ω into V –2V. Measured under DC

conditions. For dynamic measurements a tolerance of 50 mV should

be added.

5. Supply current excluding Rx output load.

LASER SAFETY

Wavelength

850 nm

This multimode Gigabit Ethernet transceiver is a Class 1 laser

product. It complies with IEC 825-1 and FDA 21 CFR 1040.10

and 1040.11. The transceiver must be operated under recom-

mended operating conditions. Because the transceiver design

is designed to be inherently eye safe, it does not require open

fiber control thus eliminating complex electronics or mechanics.

Total output power (as defined by IEC: 50 mm

aperture at 10 cm distance)

<400 µW

Total output power (as defined by FDA: 7 mm

aperture at 20 cm distance)

<70 µW

General Restrictions

Complies with 21 CFR

1040.10 and 1040.11

Class 1 Laser Product

Classification is valid only if the module is operated within the

specified temperature and voltage limits. The system using the

module must provide power supply protection that guarantees

that the system power source will cease to provide power if the

maximum recommended operation limit or more is detected on

the +3.3 V at the power source. The case temperature of the

module must be in the temperature range given in the recom-

mended operating limits. These limits guarantee the laser

safety.

Note

Failure to adhere to the above restrictions could result in a modifica-

tion that is considered an act of “manufacturing,” and will require,
