Note1: For update of the equipments and strict control of raw materials, 10Gtek has the ability to supply the customized
products since Jan 1st, 2007, which meets the requirements of RoHS6 (Restrictions on use of certain Hazardous
Substances) of European Union.
In light of item 5 in RoHS exemption list of RoHS Directive 2002/95/EC, Item 5: Lead in glass of cathode ray tubes,
electronic components and fluorescent tubes.
In light of item 13 in RoHS exemption list of RoHS Directive 2005/747/EC, Item 13: Lead and cadmium in optical and
filter glass. The three exemptions are being concerned for 10Gtek’s transceivers, because 10Gtek’s transceivers use
glass, which may contain Pb, for components such as lenses, isolators, and other electronic components.

Notes:
3. TX Fault is not used and is always tied to ground through a 100 ohm resistor.
4. TX Disable as described in the MSA is not applicable to the 1000BASE-T module, but is used for convenience as an
input to reset the internal ASIC. This pin is pulled up within the module with a 4.7KW resistor.
Low (0 – 0.8 V): Transceiver on
Between (0.8 V and 2.0 V): Undefined
High (2.0 – 3.465 V): Transceiver in reset state
Open: Transceiver in reset state
5. Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7-10KW resistor on the host
board to a supply less than VCCT+0.3V orVCCR+0.3V.
Mod Def 0 is tied to ground through a 100 ohm resistor to indicate that the module is present.
Mod-Def 1 is clock line of two wire serial interface for optional serial ID
Mod-Def 2 is data line of two wire serial interface for optional serial ID
6. LVTTL compatible with a maximum voltage of 2.5V. Not supported on HTSFP-24-111X
7. RD-/+: These are the differential receiver outputs. They are ac coupled 100 ohm differential lines which should be
terminated with 100 ohm differential at the user SerDes. The ac coupling is done inside the module and is thus not
required on the host board. The voltage swing on these lines will be between 370 and 2000 mV differential (185 – 1000
mV single ended) when properly terminated. These levels are compatible with CML and LVPECL voltage swings.
8. VCCR and VCCT are the receiver and transmitter power supplies. They are defined as 3.3 V ± 5% at the SFP
connector pin. The maximum supply current is about 300mA and the associated in-rush current will typically be no
more than 30 mA above steady state after 500 nanoseconds.
9.
TD-/+: These are the differential transmitter inputs. They are ac coupled differential lines with 100W
differential termination inside the module. The ac coupling is done inside the module and is thus not required on the
host board. The inputs will accept differential swings of 500 – 2400 mV (250 –1200 Mv single ended), though it is
recommended that values between 500 and 1200 mV differential (250 – 600 mV single ended) be used for best EMI
performance. These levels are compatible with CML and LVPECL voltage swings.
