Description
Description
PAROLI is a parallel optical link for high-speed data transmission. A complete PAROLI
system consists of a transmitter module, a 12-channel fiber optic cable, and a receiver
module. The transmitter supports LVDS, CML and LVPECL differential signals. The
receiver module is described for the LVDS electrical output only. A specification for
Infineon’s adjustable CML output can be provided separately.
Transmitter V23814-U1306-M136
The transmitter module converts parallel electrical input signals via a laser driver and a
Vertical Cavity Surface Emitting Laser (VCSEL) diode array into parallel optical output
signals. All input data signals are Multistandard Differential Signals (LVDS compatible;
they also support LVPECL and CML because of the wide common input range). The
electrical interface (LVDS, LVPECL or CML) is selected by the supply inputs V_IN. The
data rate is up to 1600 Mbit/s for each channel. The transmitter module’s min. data rate
of 500 Mbit/s is specified for the CID¹⁾ worst case pattern (disparity 72) or any pattern with
a lower disparity.
A logic low level at –RESET switches all laser outputs off. During power-up –RESET
must be used as a power-on reset which disables the laser driver and laser control until
the power supply has reached a 3.135 V level.
The Laser Controller Up (LCU) output is low if a laser fault is detected or –RESET is
forced to low.
All non data signals have LVCMOS levels.
Transmission delay of the PAROLI system is ˆ 1 ns for the transmitter, ˆ 1 ns for the
receiver and approximately 5 ns per meter for the fiber optic cable.
