• Manufacturer: Infineon Technologies Corporation

DESCRIPTION (continued)
The Siemens multimode 1.0625 GBd Fibre Channel transceiver is
a single unit comprised of a transmitter, a receiver, and an
SC receptacle. This design frees the customer from many align-
ment and PC board layout concerns. The module is designed for
low cost LAN and WAN applications. It can be used as the net-
work end device interface in mainframes, workstations, servers,
and storage devices, and in a broad range of network devices
such as bridges, routers, intelligent hubs, and switches.
This transceiver operates at 1.0625 Gbits per second from a
single power supply (+5 V). The full differential data inputs and
outputs are PECL compatible.
Functional Description of 1x9 Pin Row Transceiver
This transceiver is designed to transmit serial data via
multimode cable.
Functional Diagram
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 transmitter converts PECL compatible electrical serial data
(TD and TDnot) into optical serial data. Data lines are AC coupled
with differential 100
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 output
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 prevent 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.
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 volt-
age has risen above the reset threshold. During this time the
laser is inactive.
