V23814/15-U1306-M130 Parallel Optical Link: PAROLI
TM
Tx/Rx AC, 1.6 Gbit/s

DESCRIPTION
PAROLI is a parallel optical link for high-speed data transmis-
sion. A complete PAROLI system consists of a transmitter
module, a 12-channel fiber optic cable, and a receiver module.
Transmitter V23814-U1306-M130
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 Low Voltage Differential Signals (LVDS). The
data rate is 250-1600 Mbit/s for each channel. Electrical input
data should be DC balanced within 144 bits. The maximum
time interval of consecutive 0's and 1's (run length) should not
exceed 72 bits. This will ensure that the output jitter values
given for the transmitter and receiver in this data sheet will be
met. Otherwise, jitter values will be exceeded.
A logic low level at -RESET switches all laser outputs off. During
power-up -RESET must be used as a power-on reset which dis-
ables the laser driver and laser control until the power supply
has reached a 3 V level.
An additional Laser Active output is low if a laser fault is
detected or -RESET is forced to low.
All nondata signals have LVCMOS levels.
Transmission delay of the PAROLI system is at a maximum 1 ns
for the transmitter, 1 ns for the receiver and approximately 5 ns
per meter for the fiber optic cable.

LASER SAFETY
The transmitter of the AC coupled Parallel Optical Link (PAROLI)
is an FDA Class 1 laser product. It complies with FDA regula-
tions 21 CFR 1040.10 and 1040.11. The transmitter is also an IEC
Class 3A laser product as defined by IEC 825-1.To avoid possi-
ble exposure to hazardous levels of invisible laser radiation, do
not exceed maximum ratings.
The PAROLI module must be operated under the specified
operating conditions (supply voltage between 3.0 V and 3.6 V,
case temperature between 0C and 80C) under any circum-
stances to ensure laser safety.
Caution
Do not stare into beam or view directly with optical
instruments. The use of optical instruments with this product
may lead to eye hazard.
Note
Any modification of the module will be considered an act of "manu-
facturing," and will require, under law, recertification of the product
under FDA (21 CFR 1040.10 (i)).
Laser Emission
Laser safety design considerations
To ensure laser safety for all input data patterns each channel is
controlled internally and will be switched off if the laser safety
limits are exceeded.
An internal control unit switches the respective data channel
output off if the input duty cycle permanently exceeds 57%.
The alerter will not disable the channel below an input duty
cycle of 57% under all circumstances.
The minimum alerter response time is 1 s with a constant high
input, i.e. in the input pattern the time interval of excessive high
input (e.g. '1's in excess of a 57% duty cycle, consecutive or
non-consecutive) must not exceed 1 s, otherwise the resptive
channel will be switched off. The alerter switches the respec-
tive channel from off to on without the need of resetting the
module.
All of the channel alerters operate independently, i.e. an alert
within a channel does not affect the other channels. To
decrease the power consumption of the module unused chan-
nel inputs can be tied to high input level. In this way a portion of
the supply current in this channel is triggered to shut down by
the corresponding alerter.

DESCRIPTION
Receiver V23815-U1306-M130
The PAROLI receiver module converts parallel optical input
signals into parallel electrical output signals. The optical signals
received are converted into voltage signals by PIN diodes,
transimpedance amplifiers, and gain amplifiers. All output data
signals are Low Voltage Differential Signals (LVDS). The data
rate is 250-1600 Mbit/s for each channel. Optical input data
should be DC balanced within 144 bits. The maximum time
interval of consecutive 0's and 1's (run length) should not
exceed 72 bits. This will ensure that the output jitter values
given for the transmitter and receiver in this data sheet will be
met. Otherwise, jitter values might be exceeded.
Additional Signal Detect outputs (SD1 active high / SD12 active
low) show whether an optical AC input signal is present at data
input 1 and/or 12. The signal detect circuit can be disabled with
a logic low at ENSD. The disabled signal detect circuit will
permanently generate an active level at Signal Detect outputs,
even if there is insufficient signal input. This could be used for
test purposes.
A logic low at LVDS Output Enable sets all data outputs to logic
low. SD outputs will not be effected.
All nondata signals have LVCMOS levels. Transmission delay of
the PAROLI system is at a maximum 1 s for the transmitter,
1 s for the receiver and approximately 5 ns per meter for the
fiber optic cable.
