• Manufacturer: Infineon Technologies

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-K1306-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
data rate is up to 1250 Mbit/s for each channel.The transmitter module’s min. data rate
of 500 Mbit/s is specified for the CID
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.
