2.5 Gbps Single Mode SFF LC Transceiver
C-1X-2500(C)-FDFB-SLC4
Recommended Circuit Schematic
Inputs to the C-1X-2500(C)-FDFB-SLC4 series transmitters are AC coupled and internally terminated through 50 ohms to AC ground.
These transceivers can operate with LVPECL or CML logic levels. The input signal must have at least a 200 mV peak to (single ended) signal
swing. Output from the receiver section of the module is also AC coupled and is expected to drive into 50 ohm load. Different termination
strategies may be required depending on the particular Serializer / Deserializer chip set used.
The C-1X-2500(C)-FDFB-SLC4 series product family are designed with AC coupled data inputs and outputs to provide the following
advantages:
■ Close positioning of SERDES with respect to transceiver; allows for shorter line lengths and at gigabit speeds reduces EMI.
■ Minimum number of external components.
■ Internal termination reduces the potential for unterminated stubs which would otherwise increase jitter and reduce transmission margin.
Figure 1 & Figure 2 illustrates the recommended transmit and receive data line trminations for SERDES with CML and LVPECL Inputs / Outputs
respectively.

Signal Detect
The C-1X-2500(C)-FDFB-SLC4 transceivers are equipped with LVTTL / LVPECL signal detect outputs. The standard LVTTL output eliminates

planes. The mounting posts are at case ground and should not be connected to circuit ground. The mounting posts are at case ground and
should not be connected to circuit ground. The ferrite bead should provide a real impedance of 50 to 100 ohms at 100 to 1000 MHz. Bypass

2.5 Gbps Single Mode SFF LC Transceiver
C-1X-2500(C)-FDFB-SLC4
Printed Circuit Board Layout Consideration
A fiber-optic receiver employs a very high gain, wide bandwidth transimpedance amplifier. This amplifier detects and amplifies signals that
are only tens of nA in amplitude when the receiver is operating near its limit. Any unwanted signal currents that couple into the receiver circuitry
causes a decrease in the receiver’s sensitivity and can also degrades the of the receiver’s signal detect (SD) circuit. To minimize the coupling of
unwanted noise into the receiver, careful attention must be given to the printed circuit board.
At a minimum, a double-sided printed circuit board (PCB) with a large component side ground plane beneath the transceiver must be used.
In applications that include many other high speed devices, a multi-layer PCB is highly recommended. This permits the placement of power and
ground on separate layers, which all them to be isolated from the signal lines. Multilayer construction also permits the routing of signal traces
away from high level, high speed signal lines. To minimize the possibility of coupling noise into the receiver section, high level, high speed signals
such as transmitter inputs and clock lines should be routed as far away as possible from the receiver pins.
Noise that couples into the receiver through the power supply pins can also degrade performance. It is recommended that a pi filter in
both the transmitter and receiver power supplies.
EMI and ESC Consideration
LuminentOIC transceivers offer a metalized plastic case and a special chassis grounding clip. As shown in the drawing, this clip connects the
module case to chassis ground then installed flush through the panel cutout. The grounding clip in this way brushes the edge of the cutout in
order to make a proper contact. The use of a grounding clip also provides increased electrostatic protection and helps reduce radiated emissions
from the module or the host circuit board through the chassis faceplate. The attaching posts are at case potential and may be connected to
chassis ground. They should not be connected to circuit ground.
Plastic optical subassemblies are used to further reduce the possibility of radiated emissions by eliminating the metal from the transmitter
and receiver diode housings, which extend into connector space. By providing a non-metal receptacle for the optical cable ferrule, the gigabit
speed RF electrical signal is isolated form the connector area thus preventing radiated energy leakage from these surfaces to the outside of the
panel.
Laser Safety
This single mode transceiver is a Class1 laser product. It complies with IEC 825 and FDA 21 CFR 1040.10 and 1040.11.The transceiver must
be operated within the specified temperature and voltage limits. The optical ports of the module shall determinate with an optical connector or
with a dust plug.
