Power Coupling
A suggested layout for power and ground connections is given in Figure 1 below. Connections are made via separate voltage
and ground planes. 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 capacitors should be placed as close to the
20 pin connector as possible.

3. Mod-Def 0,1, 2. These are the module definition pins. They should be pulled up with an 4.7-10 K resistor on the host board
to a supply less than VCCT + 0.3 V or VCCR + 0.3 V.
4. RD-/+: These are the differential receiver outputs. They are ac coupled 100 Ohm differential lines which should be
terminated with 100 ohm differential. The ac coupling is done inside the module and is thus not required on the host board.
The voltage swing levels are compatible with LVPECL voltage swings.
5. VCCR and VCCT are the receiver and transmitter power supplies. They are defined as 3.3 V ± 5% at the SFP connector pin.
6. TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100 Ohm differential
termination inside the module. The ac coupling is done inside the module and is thus not required on the host board. The
inputs levels are compatible with LVPECL voltage swings.

Mating of SFP Transceiver to SFP Host Board Connector
The pads on the PCB of the SFP transceiver shall be designed for a sequenced mating as follows: First mate: Ground contacts.
Second mate: Power contacts. Third mate: Signal contacts The SFP MSA specification for a typical contact pad plating for
the PCB is 0.38 micrometers minimum hard gold over 1.27 micrometers minimum thick nickel. To ensure the long term
reliability performance after a minimum of 50 insertion removal cycles, the contact plating of the transceiver is 0.762 micron
(30 micro-inches) over 3.81 micron (150 micro-inches) of Ni on Cu contact pads.
RJ45 Connector
RJ45 connector shall support shielded and unshielded cables. Also, the connector is mechanically robust enough and
designed to prevent loss of link, when the cable is positioned or moves in different angles. The connector shall pass the
“wiggle” RJ45 connector operational stress test. During the test, after the cable is plugged in, the cable is moved in circle to
cover all 360 deg in the vertical plane, while the data traffic is on. There shall be no link or data loss.
