1x9 Transceiver

DESCRIPTION
This data sheet describes the Infineon single mode ESCON
transceiver.
The Infineon single mode ESCON transceiver is a single unit
comprised of a transmitter, a receiver, and an SC duplex single
mode receptacle. 1300 nm long wavelength technology is com-
bined with the well-established 1x9 industry standard footprint.
This design frees the customer from many alignment and PC
board layout concerns.
The system is compatible with the IBM single mode ESCON
standard and the upcoming SBCON standard of ANSI.
Based on laser technology and single mode fiber, the link can
be extended up to 20 Km and beyond.
This transceiver operates at 200 Mbit/s from a single power
supply (+5 Volt). The full differential data inputs and outputs are
PECL compatible. It is designed to be encoded with 8B/10B sig-
nal layers.
Functional Description
This transceiver is designed to transmit serial data via single
mode 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 optical data is
present
(1)
.
The transmitter converts PECL compatible electrical serial data
(TD and TDnot) into optical serial data. It 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 a constant output power of the laser over tempera-
ture 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.
This module is a Class 1 laser product, due to an integrated
automatic shutdown circuit that disables the laser when it
detects transmitter failures.
The transceiver contains a supervisory circuit to monitor 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.
Note
1. We recommend to switch off the transmitter supply (V
CC
-Tx) if no
transmitter input data is applied.

Transmitter Electro-Optical Characteristics
Note
1. Transmitter meets ANSI T1E1.2, SONET OC-3, and ITU-T G.957
mask patterns.

1 NRZ PRBS as recom-
mended by ANSI T1E1.2, SONET OC-3, and ITU-T G.957.
2. An increase in optical power of data signal above the specified level
will cause the SIGNAL DETECT to switch from a Low state to a High
state.
3. A decrease in optical power of data signal below the specified level
will cause the SIGNAL DETECT to switch from a High state to a Low
state.
4. PECL compatible. Load is 50
into V

2 V. Measured under DC
conditions at 25C. For dynamic measurements a tolerance of
50 mV should be added. V

=5 V.
5. PECL compatible. A high level on this output shows that optical data
is applied to the optical input.
