Note2: For update of the equipments and strict control of raw materials, SNR has the ability to supply the
customized products since Jan 1th, 2007, which meet 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, Item13: Lead and cadmium in optical
and filter glass. The three exemptions are being concerned for SNR’s transceivers, because SNR’s transceivers
use glass, which may contain Pb, for components such as lenses, windows, isolators, and other electronic
components.

Notes:
1) TX Fault is an open collector/drain output, which should be pulled up with a 4.7K – 10KΩ
resistor on the host board. Pull up voltage between 2.0V and VccT, R+0.3V. When high, output
indicates a laser fault of some kind. Low indicates normal operation. In the low state, the output
will be pulled to < 0.8V.
2) TX disable is an input that is used to shut down the transmitter optical output. It is pulled up
within the module with a 4.7 – 10 K Ω resistor. Its states are:
NAG LLC
Page 7 of 14
SNR-SFP2.5-WXX-10 2.5Gbps
10 dB Power Budget SFP 2.5G WDM Transceiver
Low (0 – 0.8V): Transmitter on
(>0.8, < 2.0V): Undefined
High (2.0 – 3.465V): Transmitter Disabled
Open: Transmitter Disabled
3) Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K –
10KΩresistor on the host board. The pull-up voltage shall be VccT or VccR (see Section IV for
further details). Mod-Def 0 is grounded by the module to indicate that the module is present ModDef 1 is the clock line of two wire serial interface for serial ID Mod-Def 2 is the data line of two wire
serial interface for serial ID
4) LOS (Loss of Signal) is an open collector/drain output, which should be pulled up with a 4.7K –
10KΩ resistor. Pull up voltage between 2.0V and VccT, R+0.3V. When high, this output indicates
the received optical power is below the worst-case receiver sensitivity (as defined by the standard
in use). Low indicates normal operation. In the low state, the output will be pulled to < 0.8V.
5) VeeR and VeeT may be internally connected within the SFP module.
6) RD-/+: These are the differential receiver outputs. They are AC coupled 100Ω differential lines
which should be terminated with 100Ω (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.
7) VccR and VccT are the receiver and transmitter power supplies. They are defined as 3.3V ±5%
at the SFP connector pin. Maximum supply current is 300mA. Recommended host board power
supply filtering is shown below. Inductors with DC resistance of less than 1 ohm should be used in
order to maintain the required voltage at the SFP input pin with 3.3V supply voltage. When the
recommended supply-filtering network is used, hot plugging of the SFP transceiver module will
result in an inrush current of no more than 30mA greater than the steady state value. VccR and
VccT may be internally connected within the SFP transceiver module.
8) TD-/+: These are the differential transmitter inputs. They are AC-coupled, differential lines with
100Ω 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 – 1200mV single-ended), though it is recommended that values between 500 and 1200 mV
differential (250 – 600mV single-ended) be used for best EMI performance.
EEPROM
The serial interface uses the 2-wire serial CMOS EEPROM protocol defined for the ATMEL
AT24C02/04 family of components. When the serial protocol is activated, the host generates the
serial clock signal (SCL). The positive edge clocks data into those segments of the EEPROM that
are not writing protected within the SFP transceiver. The negative edge clocks data from the SFP
transceiver. The serial data signal (SDA) is bi-directional for serial data transfer. The host uses
NAG LLC

SNR-SFP2.5-WXX-10 2.5Gbps
10 dB Power Budget SFP 2.5G WDM Transceiver
SDA in conjunction with SCL to mark the start and end of serial protocol activation. The memories
are organized as a series of 8-bit data words that can be addressed individually or sequentially.
The Module provides diagnostic information about the present operating conditions. The
transceiver generates this diagnostic data by digitization of internal analog signals. Calibration and
alarm/warning threshold data is written during device manufacture. Received power monitoring,
transmitted power monitoring, bias current monitoring, supply voltage monitoring and temperature
monitoring all are implemented. The diagnostic data are raw A/D values and must be converted to
real world units using calibration constants stored in EEPROM locations 56 – 95 at wire serial bus
address A2h. The digital diagnostic memory map specific data field define as following .For detail
EEPROM information, please refer to the related document of SFF 8472 Rev 9.3.
